+%%% The size of the original cacm.bib file
+%%% covering 1958--1996 became too large (about
+%%% 4000 entries) for BibTeX and TeX to handle,
+%%% so at version 1.44, it was split into
+%%% cacm1950.bib, cacm1960.bib, cacm1970.bib,
+%%% cacm1980.bib, and cacm1990.bib, each covering
+%%% the decade starting with the year embedded in
+%%% the filename. Version numbers for these
+%%% files begin at 2.00.
+%%%
+%%% Volumes from the 1990s average more than 200
+%%% articles yearly, so a complete bibliography
+%%% for this journal could contain more than 6000
+%%% entries from 1958 to 2000.
+%%%
+%%% These bibliographies also include ACM
+%%% Algorithms 1--492. For Algorithms 493--686,
+%%% including Algorithm 568, published in ACM
+%%% Transactions on Programming Languages and
+%%% Systems (TOPLAS), see the companion
+%%% bibliographies, toms.bib and toplas.bib.
+%%%
+%%% All published Remarks and Corrigenda are
+%%% cross-referenced in both directions, so
+%%% that citing a paper will automatically
+%%% generate citations for those Remarks and
+%%% Corrigenda. Cross-referenced entries are
+%%% duplicated in cacm19*.bib and toms.bib, so
+%%% that each is completely self-contained.
+%%%
+%%% Source code for ACM Algorithms from 380
+%%% onwards, with some omissions, is available
+%%% via the Netlib service at
+%%% http://netlib.ornl.gov/, and
+%%% ftp://netlib.bell-labs.com/netlib/toms.
+%%%
+%%% There is a World Wide Web search facility
+%%% for articles published in this journal from
+%%% 1959 to 1979 at
+%%% http://ciir.cs.umass.edu/cgi-bin/web_query_form/public/cacm2.1.
+%%%
+%%% The initial draft of entries for 1981 --
+%%% 1990 was extracted from the ACM Computing
+%%% Archive CD ROM for the 1980s, with manual
+%%% corrections and additions. Additions were
+%%% then made from all of the bibliographies in
+%%% the TeX User Group collection, from
+%%% bibliographies in the author's personal
+%%% files, from the Compendex database
+%%% (1970--1979), from the IEEE INSPEC database
+%%% (1970--1979), from tables of contents
+%%% information at http://www.acm.org/pubs/cacm/,
+%%% from Zentralblatt fur Mathematik Mathematics
+%%% Abstracts at
+%%% http://www.emis.de/cgi-bin/MATH/, from
+%%% bibliographies at Internet host
+%%% netlib.bell-labs.com, and from the computer
+%%% science bibliography collection on
+%%% ftp.ira.uka.de in /pub/bibliography to which
+%%% many people of have contributed. The
+%%% snapshot of this collection was taken on
+%%% 5-May-1994, and it consists of 441 BibTeX
+%%% files, 2,672,675 lines, 205,289 entries, and
+%%% 6,375 <at>String{} abbreviations, occupying
+%%% 94.8MB of disk space.
+%%%
+%%% Numerous errors in the sources noted above
+%%% have been corrected. Spelling has been
+%%% verified with the UNIX spell and GNU ispell
+%%% programs using the exception dictionary
+%%% stored in the companion file with extension
+%%% .sok.
+%%%
+%%% BibTeX citation tags are uniformly chosen
+%%% as name:year:abbrev, where name is the
+%%% family name of the first author or editor,
+%%% year is a 4-digit number, and abbrev is a

+%%% words. Citation tags were automatically

A minimal perimeter polygon subjected to specified constraints is then chosen as the approximating contour. The determination of the minimal polygon can be reduced to a nonlinear programming problem, solved by an algorithm which takes into account the weak bonds between variables. Some examples are presented, and the corresponding computing times are listed.",

The M \& N procedure assigns to a MAX (MIN) node some function of the M (N) highest (lowest) valued successors. An M \& N procedure was written in LISP to play the game of kalah, and it was demonstrated that the M \& Nprocedure is significantly superior to the mini-max procedure.

Two algorithms for programming decision tables whose merits are simplicity of implementation and detection of ambiguities at execution time are presented. The first algorithm is for limited entry decision tables and clarifies the importance of proper coding of the information in the decision table. The second algorithm programs a mixed entry decision table directly without going through the intermediate step of conversion to a limited entry form, thereby resulting in storage economy.

The tapes are logically similar to a disk. Priority was given to the design of efficient tape algorithms to minimize the limitations of the small memory. Techniques developed for handling scroll editing, filing, and the layered system structure are outlined.",

The paradigm problem considered is that of testing a series of messages one-by-one for membership in a given set of messages. Two new hash-coding methods are examined and compared with a particular conventional hash-coding method. The computational factors considered are the size of the hash area (space), the time required to identify a message as a nonmember of the given set (reject time), and an allowable error frequency. The new methods are intended to reduce the amount of space required to contain the hash-coded information from that associated with conventional methods. The reduction in space is accomplished by exploiting the possibility that a small fraction of errors of commission may be tolerable in some applications, in particular, applications in which a large amount of data is involved and a core resident hash area is consequently not feasible using conventional methods. An example is discussed which illustrates possible areas of application for the new method.",

The algorithm is also compared with several previous parsers for context-sensitive grammars and general rewriting systems, and the difference between the two types of analyses is discussed.

Generations of cryptanalysts have expended untold man-years, thus far without success, attempting tode code them; vast armies of fortune hunters and treasure seekers have devoted Herculean labors to digging up the rolling hills of Virginia trying to locate the promised bonanza. \par The history of pertinent activities would fill volumes, yet serious students of cryptography have always had nagging doubts about the cyphers' authenticity. It has been alleged that the ``known solution'' to Cypher Number Two: 115, 73, 24, 818, 37, 52, 49, \ldots{} (``I have deposited in the County of Bedford about four miles from Buford's in an excavation or vault \ldots{}'') with the aid of an unsanitized version of the Declaration of Independence was merely a superb, imaginative, and grandiose hoax perpetrated ages ago for whatever reasons. Modern computer technology could obviously perform signature analyses the process of encoding itself so as to yield new clues and deeper insights into their construction. For the benefit of the uninitiated, the encoding method used in the second cypher employs a specified document whose words are simply numbered consecutively, and first letters of these words are sought out at random to match the letters of these words are sought out at random to match the letters of the clear text or message. \par The sequence of numbers corresponding to these matches is then written down as the final code. While primitive, the process has the advantage of relative security until the source document becomes known; at that moment the cypher can be decoded even by second graders. The work now completed with the help of our UNIVAC 1108 includes numerous analytical studies of the Beale cyphers and various types of simulations. \par For example, we have turned the entire process of simulated encoding by various schemes over to the machine and analyzed the signatures of these synthetic codes; we have also encoded various messages by hand, using different texts and a variety of methods to obtain their signatures. These simulations provide convincing evidence that the signatures are both process and data dependent; they indicate also very strongly that Mr. Beale's cyphers are for real and that it is merely a matter of time before someone finds the correct source document and locates the right vault in the common-wealth of Virginia.",

MULTIPLE's proving program (PP) uses two evaluation functions to guide its search for a proof of whether or not a particular goal is achievable. Thirteen general features of predicate calculus clauses were created for use in the automatic learning of better evaluation functions for PP. A multiple regression program was used to produce optimal coefficients for linear polynomial functions in terms of the features.\par Also, automatic data-handling routines were written for passing data between the learning program and the proving program, and for analyzing and summarizing results. Data was generally collected for learning (regression analysis) from the experience of PP. A number of experiments were performed to test the effectiveness and generality of the learning program. Results showed that the learning produced dramatic improvements in the solutions to problems which were in the same domain as those used for collection learning data. Learning was also shown to generalize successfully to domains other than those used for data collection. Another experiment demonstrated that the learning program could simultaneously improve performance on problems in a specific domain and on problems in a variety of domains.

If this particular area is full, then the entry will be placed into the slower second-level store, even though other areas in the first-level store may have space available. Given that N entries have been filed in the entire hierarchy, an expression is derived for the expected number of entries filed in the first-level store.

In a nonoriented complete graph with n vertices, Hamiltonian circuits equivalent to $.5(n - 1)!$ specific permutations of $n$ elements, termed rosary permutations, can be defined. Each of them corresponds to two circular permutations which mirror-image each other, and is generated successively by a number system covering $3*4*\ldots*(n-1)$ sets of edges. Every set of edges $\{E[k]\}, 1 <= E[k] <= k, 3 <= k <= (n-1)$ is determined recursively by constructing a Hamiltonian circuit with $k$ vertices from a Hamiltonian circuit with $k-1$ vertices, starting with the Hamiltonian circuit of 3 vertices. The basic operation consists of transposition of a pair of adjacent vertices where the position of the pair in the permutation is determined by $\{E[k]\}$. Two algorithms treating the same example for five vertices are presented. It is very easy to derive all possible n! permutations from the $.5(n - 1 )!$ rosary permutations be cycling the permutations and by taking them in the reverse order-procedures which can be performed fairly efficiently by computer.",

A spanning tree with labeled edges is grown, two edges finally bearing different labels if and only if they belong to different blocks. For both representations the time required to analyze a graph on $n$ nodes increases as $n^G$ where $G$ depends on the type of graph, $1 <= G <= 2$, and both bounds are attained. \par Values of G are derived for each of several suitable families of test graphs, generated by an extension of the web grammar approach.

First some standard terminology is introduced. Then the input buffer allocation method is described, followed by an analysis of the improvement to be expected over more conventional allocation. This analysis makes use of a particular distribution function. An analysis of a completely different distribution is given which yields similar results. This suggests that the results do not depend on a particular distribution function. An optimum output buffer size is also determined. It is concluded that this buffering allocation can significantly reduce the time of merge sorting on movable arm disks when the input data are not random, and that this output buffer allocation should be used whether the data is random or not.",

This paper shows that expression execution time can be minimized only if consideration is given to the ordering of the subexpressions. In particular, subexpressions should be executed in order of decreasing memory and processor time requirements. This observation is valid for configurations ranging from a uniprocessor with an unbuffered main memory to multiprocessor with a ``cache'' buffer memory. If the number of subexpressions which can be executed in parallel exceeds the number of available processors, then execution of some of these subexpressions must be postponed. A procedure is given which combines this requirement with the earlier ordering considerations to provide an optimal execution sequence.",

This procedure may be used for counting patterns on a matrix, and a hardware implementation of the algorithm using large scale integrated technology is envisioned. The principal features of this method are the very small window employed (two-by-two elements), the parallel nature of the process, and the possibility of shrinking any pattern, regardless of the complexity of its configuration. Problems regarding merging and disconnection of patterns during the process as well as the determination of the maximum number of steps necessary to obtain a single isolated element from a pattern, are reviewed and discussed. An analogy with a neural network description, in terms of McCulloch-Pitts ``neurons'' is presented.",

The high cost of these cosine transformations has been a serious drawback in using Clenshaw-Curtis quadrature. \par Two other problems related to the cosine transformation have also been trouble some. First, the conventional computation of the cosine transformation by recurrence relation is numerically unstable, particularly at the low frequencies which have the largest effect upon the integral. Second, in case the automatic scheme should require refinement of the sampling, storage is required to save the integrand values after the cosine transformation is computed. This second part of the paper shows how the cosine transformation can be computed by a modification of the fast Fourier transform and all three problems overcome. The modification is also applicable in other circumstances requiring cosine or sine transformations, such as polynomial interpolation through the Chebyshev points.",

Problem-oriented languages may very well become the most important language development area in the next five to ten years.\par In the operating system area all major computer manufacturers set out to produce very ambitious multiprogramming systems, and they all ran into similar problems. A number of university projects,though not directly comparable to those of the manufacturers, have contributed greatly to a better understanding of operating system principles. Important trends include the increased interest in the development of system measurement and evaluation techniques,and increased use of microprogramming for some programming system functions.",

Various modes of partitioning are defined for different types of arrays, so that subarrays may vary over the original array in a nearly arbitrary manner. These definitions are motivated with several realistic examples to illustrate the value of partitioning for array languages. Of general interest is the data structure for partitioning. This consists of dynamic tree structures which are used to derive and maintain the array control information. These are described in sufficient detail to be of value in the design of other array languages. The description presented in this paper is implemented in a new array language, OL/2, currently under development at the University of Illinois.",

The algorithm is similar to those of Rutishauser and Schwartz for the reduction of symmetric matrices to band form. The calculation of C requires order N**2m operation.

This freedom simplified both incremental compilation and the system's addressing structure, and centralized the communication mechanisms enabling the construction of hierarchical subsystems. It also suggested an important new concept for operating systems: separation of the scheduling from the maintenance functions in resource allocation. This separation enables incorporation of new scheduling algorithms (decision of what to do) without endangering the system integration (correctly performing the scheduling decisions).",

For the most part this assistance is implicit and is provided automatically by the compilers. The most remarkable characteristic of PL/C is its perseverance --- it completes translation of every program submitted and continues execution until a user-established error limit is reached. This requires that the compiler repair errors encountered during both translation and execution, and the design of PL/C is dominated by this consideration. PL/C also introduces several explicit user-controlled facilities for program testing. To accommodate these extensions to PL/I without abandoning compatibility with the IBM compiler, PL/C permits ``pseudo comments'' --- constructions whose contents can optionally be considered either source text or comment. In spite of the diagnostic effort PL/C is a fast and efficient processor. It effectively demonstrates that compilers can provide better diagnostic assistance than is customarily offered, even when a sophisticated source language is employed, and that this assistance need not be prohibitively costly.",

In particular, it is shown that it may not be necessary to multiprogram in such a situation. \par In the past, backing storage devices have been roughly symmetric with respect to their read and write times. This situation may not continue, as several devices are currently under development which may have a very small read-time/write-time ratio.

On the IBM 360-65, COKO III plays a minimal chess game at the rate of. 2 sec cpu time per move, with a level close to lower chess club play. A selective tree searching procedure controlled by tactical chess logistics allows a deployment of multiple minimal game calculations to achieve some optimal move selection. In addition, an interesting phenomenon called a tree searching catastrophe has plagued COKO's entire development just as it troubles a human player. Standard exponential growth is curbed to a large extent by the definition and trimming of the Fischer set.

Teaching someone how to program is similar to teaching him to play a musical instrument: neither skill can be taught-they must be learned. However, the teacher still serves several vital purposes: to present a set of rules for producing well-formed utterances; to offer numerous demonstrations of his own skill; and to function as an involved critic. Finally, the teacher is the source of information about the process in which the student is involved.",

The program was constructed to use a ``strategy signature table'' which classifies board situations through the interactions of game parameters. Each entry in the table contains adaptively determined weights indicating the advisability of various strategies. Once chosen, a strategy then employs probability analysis and linear polynomial evaluation to choose a move. Our program wins approximately two-thirds of its games in tournament situations, and has defeated championship players.",

It is thus more general than the previously published heuristic algorithms. Compared to the optimal algorithm of Reinwald and Soland, this algorithm is easy to code and takes a much smaller translation time; it is thus felt that it is more useful in practice.

As a practical application of such a model this paper considers the design of a novel tree search scheme based on a bit vector representation of data and shows that essentially the same algorithm can be used to design either an ideal search tree or a bit-vector tree.

The technique of dynamic verification allows the construction of an operating system which does not make certain decisions improperly even in the presence of a single hardware or software fault. Furthermore, multiple faults lead to unreliable operation only if the faults happen to reinforce each other. On PRIME, dynamic verification is used to ensure that one user's information cannot become available to another user gratuitously even in the presence of a single hardware or software fault.",

In the input translation grammar, each BNF syntactic rule corresponds to a (possibly empty) ``code generator'' realizable as an assembly language, FORTRAN or Algol, subroutine that is called whenever that syntactic rule is applied in the parse of a program. Typical one-pass compilers constructed by the PGS translate source programs at speeds approaching 14,000 cards per minute. For an XPL compiler, the parser program and its tables currently occupy 288 words of 60-bit core memory of which 140 words are parsing table entries and 82 words are links to code generators.",

Because of the list processing procedures used, only a single pass through the XY display file is required when generating the binary image and only a slight increase in execution time over the fully buffered core results.

It is proved that the diagonals of the LU decomposition converges when floating-point precision. It is also proved that the computed LU decomposition converges when floating-point arithmetic is used and that the limits of the LU diagonals using floating point are roughly within machine precision of the limits using real arithmetic. This fact is exploited to reduce the number of floating-point operations required to solve a linear system from $8n-7$ to $5n+2k-3$, where $k$ is much less than $n$, the order of the matrix. If the elements of the subdiagonals and superdiagonals are 1, then only $4n+2k-3$ operations are needed. The entire LU decomposition takes $k$ words of storage, and considerable savings in array subscripting are achieved. Upper and lower bounds on $k$ are obtained in terms of the ratio of the coefficient matrix diagonal constants and parameters of the floating-point number system. Various generalizations of these results are discussed.",

Consider the class of sparse matrices which can be tridiagonalized using only row and corresponding column permutations. The advantages of using such a transformation include the absence of round-off errors and improved computation time when compared with standard transformations. \par A graph theoretic algorithm which examines an arbitrary $n \times n$ matrix and determines whether or not it can be permuted into tridiagonal form is given. The algorithm requires no arithmetic while the number of comparisons, the number of assignments, and the number of increments are linear in $n$. This compares very favorably with standard transformation methods. \par If the matrix is permutable into tridiagonal form, the algorithm gives the explicit tridiagonal form. Otherwise, early rejection will occur.",

The scheme is based on using a function H which the would-be intruder is unable to invert. This function is applied to the user's password and the result compared to a table entry, a match being interpreted as authentication of the user. The intruder may know all about H and have access to the table, but he can penetrate the system only if he can invert H to determine an input that produces a given output.

There is no simple method for generating gamma random variates with non-integral shape parameters. A common procedure is to approximately generate such random variables by the use of the so-called probability switch method. Another procedure, which is exact, is due to Joehnk. This paper presents a rejection method for exactly generating gamma random variables when alpha is greater than 1. The efficiency of the rejection method is shown to be better than the efficiency of M. D. Joehnk's method. The paper concludes that when alpha is non-integral, the following mix of procedures yields the best combination of accuracy and efficiency: (1) when alpha is less than 1, use Joehnk's method; (2) when 1 is less than alpha and alpha is less than 5, use the rejection method; (3) when alpha is greater than 5, use the probability switch method.",

Most of these formulations can be presented in the terminology of classical Network Theory. \par One such formulation is: Given a nondirected network, partition its nodes into a minimal number of subsets such that no two members of the same subset are connected by an arc. An obvious lower limit to this number is the size of the largest strongly connected subgraph. Kirchgassner proved that an upper limit is this size plus one. One logical extension of the previous work is the introduction of variable length examinations where $W(I)$ is the number of periods for exam $I$. The object of this paper is to generalize the definition of largest strongly connected subgraph to include the weighting of nodes, to present an approximate algorithm which usually finds the largest strongly connected subgraph, and to discuss the application of this algorithm to the solution of school scheduling and exam scheduling problems.",

In over half of the cases the compressed code results from the conventional BCD code by simple removal of redundant 0 bits. A long decimal message can be subdivided into three-digit blocks, and separately compressed; the result differs from the asymptotic minimum length by only 0.34 percent. The hardware requirement is small, and the mappings can be done manually.",

For typical expressions, the size and font changes, positioning, line drawing, and the like necessary to print according to mathematical conventions are all done automatically. For example, the input {\tt sum from i=0 to infinity x sub i=pi over 2} produces $\sum_{i=0}^\infty x_i = \pi/2$. The syntax of the language is specified by a small context-free grammar; a compiler-compiler is used to make a compiler that translates this language into typesetting commands. Output maybe produced on either a phototypesetter or on a terminal with forward and reverse half-line motions. The system interfaces directly with text formatting programs, so mixtures of text and mathematics may be handled simply. This paper was typeset by the authors using the system described.",

For exponential and hyperexponential distributions of requests, first-fit outperformed best-fit; but for normal and uniform distributions, and for exponential distributions distorted in various ways, best-fit outperformed first-fit. It is hypothesized that when first-fit outperforms best-fit, it does so because first-fit, by preferentially allocating toward one end of memory, encourages large blocks to grow at the other end. Sufficient contiguous space is thereby more likely to be available for relatively large requests. Results of simulation experiments supported this hypothesis and showed that the relative performance of first-fit and best-fit depends on the frequency of requests that are large compared to the average request. when the coefficient of variation of the request distribution is greater than or approximately equal to unity, first-fit outperformed best-fit.",

In the case where m and n are of the same order of magnitude, i.e. n equals km with k being a constant, the algorithm requires 2 left bracket log//2(m plus 1) right bracket plus right bracket m/p right bracket (3 plus k) steps. These performances compare very favorably with the previous best parallel merging algorithm, Batcher's algorithm, which requires n/p plus ((m plus n)/2p)log//2m steps in the general case and km/p plus ((k plus l)/2)(m/p)log//2m in the special case where n equals km.",

In the first case, it is shown that for every k there exists an O(n**k** plus **2) algorithm for testing the LR(k) property, where n is the size of the grammar in question. On the other hand, if both k and the subject grammar are problem parameters, then the complexity of the problem depends very strongly on the representation chosen for k.

The relations between this representation of the minimization problem and a dynamic programming approach are discussed, showing that the graph search method can lead to substantial improvements in computing time. Moreover, if heuristic search methods are used, the computing time will depend on the amount of noise in the picture. Some experimental results are given; these show how various information about the shape of the contour of an object can be embedded in the figure of merit, thus allowing the extraction of contours from noisy pictures and the separation of touching objects.",

The language allows the flexible definition of geometric objects and elements, computes their parameters, and displays the results. It also provides the capability of specifying a geometric figure via a collection of parameters and displaying various loci corresponding to these parameters. A third characteristic consists of the possibility of using this language to design other user oriented languages. LG has been specifically designed for use by nonprogrammers; it is easy to learn and very close to the natural language used in geometry.",

An induction principle is presented which treats the control and data state sets on the same ground. Through the use of ``place variables'', it is observed that certain correctness conditions can be expressed without enumeration of the set of all possible control states. Examples are presented in which the induction principle is used to demonstrate proofs of mutual exclusion. Also discussed is an extension of the program model which allows each process to have its own local variables and permits shared global variables.

Algorithms for recovering discarded list structures in this manner are presented and analyzed to determine sufficient conditions under which the list processor never need to wait on the collector. These techniques are shown to require at most twice as much processing power as regular garbage collectors, if they are used efficiently. The average behavior of the program is shown to be very nearly equal to the worst-case performance, so that the sufficient conditions are also suitable for measuring the typical behavior of the algorithm.",

Second, a meaningful way is provided to vary the amount of detail presented in a scene. Third, ``clipping'' becomes a very fast logarithmic search for the resolvable parts of the environment within the field of view. Fourth, frame to frame coherence and clipping define a graphical ``working set,'' or fraction of the total structure that should be present in primary store for immediate access by the visible surface algorithm. Finally, the geometric structure suggests a recursive descent, visible surface algorithm in which the computation time potentially grows linearly with the visible complexity of the scene.",

In attempting to solve these linear programming models, using IBM's MPS package, instances of cycling were encountered. Small perturbations in the input data resulted in problems which did not cycle. This fact, plus several other observed phenomena suggest that the primary reason that cycling is not known to occur more frequently is that round-off errors in the computations perturb the problem sufficiently to prevent cycling (or at least to prevent indefinite cycling).",

The proposed attitude aims at retaining the purity of the nondeterministic formulation of search processes on one level (the attempt level), deferring the coordination of problem solving efforts to another (the choice level). The feasibility of recognizing these two levels is discussed, stressing that the structure to be managed at the choice level is a tree of contexts. The leaves are computational environments, each holding an alternative under inspection, while the other nodes are associated with choice points. According to the proposed programming style, a generative function is associated with each choice point, which expresses the desired choice strategy. The main advantage of this approach is the localization of the search strategies: Each nonterminal node of the tree keeps track of the state of the computation as it was when the choice point was last interrogated, holding at the same time the strategy to coordinate the available alternatives. Examples are given in term of ND-Lisp, an extension of Lisp designed and implemented according to these guidelines.",

Home memory organization is shown to be particularly suited to certain specialized computational problems as well as to possess advantages in terms of interference and reliability for general purpose computation.

During the search operation, the characters of pat are matched starting with the last character of pat. The information gained by starting the match at the end of the pattern often allows the algorithm to proceed in large jumps through the text being searched. Thus the algorithm has the unusual property that, in most cases, not all of the first i characters of string are inspected. The number of characters actually inspected (on the average) decreases as a function of the length of pat. For a random English pattern of length 5, the algorithm will typically inspect i/4 characters of string before finding a match at i. Furthermore, the algorithm has been implemented so that (on the average) fewer than i plus patlen machine instructions are executed. These conclusions are supported with empirical evidence and a theoretical analysis of the average behavior of the algorithm. The worst case behavior of the algorithm is linear in i plus patlen, assuming the availability of array space for tables linear in patlen plus the size of the alphabet.",

A new derivation is given, and it is shown that previous derivations make an assumption that may be violated frequently. On the basis of the simulation data and the derivation, it is hypothesized that the anomalous behavior results from the combined effects of systematic placement and the statistics of the release process. Additional simulations support this hypothesis. Systematic placement, which refers to the natural convention of always allocating storage requests against the same end of the free block selected by the allocation strategy, tends to order blocks within contiguous groups, according to their allocation time. The degree of anomalous behavior depends on the extent to which allocated blocks are released in the order of their allocation. For non-Markovian release processes, the extent of the correlation between allocation order and release order varies approximately inversely with the coefficient of variation of the memory residence time distribution. The simulations show that allocation efficiency depends strongly on the residence time distribution; efficiency decreases as the distribution's coefficient of variation increases. Some practical implications are briefly discussed.",

However, for nonuniformly distributed sets, this method can give rather sparse tables. The second method, the ``remainder reduction'' method, is not complete in the above sense, but it seems to give minimal (or almost minimal) tables for every kind of set. The two techniques are applicable directly to small sets. Some methods to extend these results to larger sets are also presented.

The intermittent-assertion method is presented with a number of examples of correctness and termination proofs.

A highly compact instruction encoding scheme is presented, which can reduce program size by a factor of 3.

For a ratio of 100:1, 10\slash 11 of a full cycle should be covered quickly and 1/11 should be covered slowly. As device manufacturers increase this ratio, the average latency for a block transfer will slowly decrease.

Moreover the method is optimal in the sense that its complexity cannot be reduced in order of magnitude. This result, coupled with earlier results by D. S.

The objective is to find a transformed digital picture of a given picture such that the sum of absolute errors between the gray level histogram of the transformed picture and that of a reference picture is minimized. This is equivalent to placing k1 linearly ordered objects of different sizes one by one into k2 linearly ordered boxes of assorted sizes, such that the accumulated error of space underpacked or overpacked in the boxes is minimized; the placement function is monotonic, which ensures a polynomial time solution to this problem.

As a case study, the implementation of a simulation of a model of the CPU-memory subsystem of the IBM 360\slash 191 is described. The results of evaluating some alternative system designs are discussed. The experiments reveal that, for the case study, the major bottlenecks in the system are the memory unit and the fixed point unit. Further, it appears that many of the sophisticated pipelining and buffering techniques implemented in the architecture of the IBM 360\slash 91 are of little value when high-speed (cache) memory is used, as in the IBM 360\slash 195.",

Even inspection techniques for certain industrial parts may be improved by this means. The required alignment is achieved by matching the real image with a synthetic image obtained from a surface model and known positions of the light sources. The synthetic image intensity is calculated using the reflectance map, a convenient way of describing surface reflection as a function of surface gradient.

A split tree is a binary search tree each node of which contains two key values --- a node value which is a maximally frequent key in that subtree, and a split value which partitions the remaining keys (with respect to their lexical ordering) between the left and right subtrees. A median split tree (MST) uses the lexical median of a node's descendents as its split value to force the search tree to be perfectly balanced, achieving both a space efficient representation of the tree and high search speed. Unlike frequency ordered binary search trees, the cost of a successful search of an MST is log n bounded and very stable around minimal values. Further, an MST can be built for a given key ordering and set of frequencies in time n log n, as opposed to n**2 for an optimum binary search tree. A discussion of the application of MST's to dictionary lookup for English is presented, and the performance obtained is contrasted with that of other techniques.",

The former technique is quite effective, but its time and space requirements are independent of how ``easy'' the given table is. Furthermore, it cannot be used to produce good, quasioptimal solutions The branch-and-bound technique uses a good heuristic to direct the search, but is cluttered up by an enormous search space, since the number of solutions increases with the number of test variables according to a double exponential. In this paper authors suggest a heuristically guided top-down search algorithm which, like dynamic programming, recognizes identical subproblems but which can be used to find both optimal and quasioptimal solutions. A heuristic search method is introduced that combines the positive aspects of the above two techniques. Compressed tables with a large number of variables can be handled without deriving expanded tables first.",

To this list of algorithms is added (6) reverse path forwarding, a broadcast routing method which exploits routing procedures and data structures already available for packet switching. Reverse path forwarding is a practical algorithm for broadcast routing in store-and-forward packet switching computer networks.

Direct control of ordering seems to simplify correctness arguments and also simplifies implementation in distributed systems. The mechanism is defined formally, and then several examples of its uses are given.

Since a central hyperplane does not favor one class or the other, it should have a lower error rate in classifying new points and is therefore better than a noncentral hyperplane.

The co-authors of the report are: Gordon Bell, Digital Equipment Corporation; Bernard A. Galler, University of Michigan; Patricia Goldberg, IBM Corporation; John Hamblen, University of Missouri at Rolla; Elliot Pinson, Bell Telephone Laboratories; and Ivan Sutherland, California Institute of Technology. Also participating in the workshop were representatives of NSF and other government agencies. In addition to the authors, a number of other people have contributed to the contents of this report. In preparation for the original workshop, all doctorate-granting computer science departments in the nation were asked for comments and suggestions on the problems of experimental computer science. A version of the current report dated January 15 was circulated to these departments and to a number of industrial and government groups for criticism. The editors and authors of this final version gratefully acknowledge the contribution of a large number of other people at all stages in the preparation of the report. \par Note: Following this presentation of the report, there is a position paper on the crisis in experimental computer science written by the ACM Executive Committee.",

The algorithm operates in time $O(\log n)$, where $n$ is the number of nodes in the tree. This represents an improvement over the best previous ly known insertion algorithms of Hirschberg and Kosaraju, which require time $O(\log 2n)$. Moreover, the $O(\log n)$ complexity is optimal. Earlier results have shown that deletion in such a structure can also be performed in $O(\log n)$ time. Thus the result of this paper gives a negative answer to the question of whether such trees should be the first examples of their kind, where deletion has a smaller time complexity than insertion. Furthermore, it can now be concluded that insertion, deletion, and retrieval in OSHB trees can be performed in the same time as the corresponding operations for the more general AVL trees, to within a constant factor. However, the insertion and deletion algorithms for OSHB trees appear much more complicated than the corresponding algorithms for AVL trees.",

For a graph of e edges, the algorithm has a worst-case time bound of 0(e log e) function operations. It is also shown that in programming terms, the number of operations is proportional to e plus the number of exits from program loops. Consequently a restriction to one-entry one-exit control structures guarantees linearity. The algorithm can be extended to yet larger classes of function spaces and graphs by relaxing the time bound. Examples are given of code improvement problems which can be solved using the algorithm.",

Several algorithms for determining the number of components in the graph associated with a particular set of elements are constructed and compared. When the classification process operates on independently-drawn samples of $n$ distinct elements from a population, the expected number of components is shown to be obtainable recursively for a class of problems called separable; in all cases, estimates are available to reach any desired level of accuracy. Clustering models in Euclidean space are analyzed in detail and asymptotic formulas obtained to complement experiments. Conjectures concerning the general behavior of the expected number of components are presented also. Finally, several computational tools of general interest are improved significantly.",

+%%% The size of the original cacm.bib file
+%%% covering 1958--1996 became too large (about
+%%% 4000 entries) for BibTeX and TeX to handle,
+%%% so at version 1.44, it was split into
+%%% cacm1950.bib, cacm1960.bib, cacm1970.bib,
+%%% cacm1980.bib, and cacm1990.bib, each covering
+%%% the decade starting with the year embedded in
+%%% the filename. Version numbers for these
+%%% files begin at 2.00.
+%%%
+%%% Volumes from the 1990s average more than 200
+%%% articles yearly, so a complete bibliography
+%%% for this journal could contain more than 6000
+%%% entries from 1958 to 2000.
+%%%
+%%% These bibliographies also include ACM
+%%% Algorithms 1--492. For Algorithms 493--686,
+%%% including Algorithm 568, published in ACM
+%%% Transactions on Programming Languages and
+%%% Systems (TOPLAS), see the companion
+%%% bibliographies, toms.bib and toplas.bib.
+%%%
+%%% All published Remarks and Corrigenda are
+%%% cross-referenced in both directions, so
+%%% that citing a paper will automatically
+%%% generate citations for those Remarks and
+%%% Corrigenda. Cross-referenced entries are
+%%% duplicated in cacm19*.bib and toms.bib, so
+%%% that each is completely self-contained.
+%%%
+%%% Source code for ACM Algorithms from 380
+%%% onwards, with some omissions, is available
+%%% via the Netlib service at
+%%% http://netlib.ornl.gov/, and
+%%% ftp://netlib.bell-labs.com/netlib/toms.

+%%% There is a World Wide Web search facility
+%%% for articles published in this journal from

+%%%
+%%% The initial draft of entries for 1981 --
+%%% 1990 was extracted from the ACM Computing
+%%% Archive CD ROM for the 1980s, with manual
+%%% corrections and additions. Additions were
+%%% then made from all of the bibliographies in
+%%% the TeX User Group collection, from
+%%% bibliographies in the author's personal
+%%% files, from the Compendex database
+%%% (1970--1979), from the IEEE INSPEC database

The M \& N procedure assigns to a MAX (MIN) node some function of the M (N) highest (lowest) valued successors. An M \& N procedure was written in LISP to play the game of kalah, and it was demonstrated that the M \& Nprocedure is significantly superior to the mini-max procedure. The statistical significance of important conclusions is given.

It is pointed out that any attempt at resolving ambiguities at compile time will, in general, be impossible. It is shown that, as a consequence, three methods of converting decision tables to programs are inadequate in regard to ambiguity detection. Two algorithms for programming decision tables whose merits are simplicity of implementation and detection of ambiguities at execution time are presented. The first algorithm is for limited entry decision tables and clarifies the importance of proper coding of the information in the decision table. The second algorithm programs a mixed entry decision table directly without going through the intermediate step of conversion to a limited entry form, thereby resulting in storage economy. A comparison of the algorithms and others proposed in the literature is made. Some features of a decision table to FORTRAN IV translator developed for the IBM 7044 are given.",

Existing noninferential, formatted data systems provide users with tree-structured files or slightly more general network models of the data. In Section 1, inadequacies of these models are discussed. A model based on $n$-ary relations, a normal form for data base relations, and the concept of a universal data sublanguage are introduced. In Section 2, certain operations on relations (other than logical inference) are discussed and applied to the problems of redundancy and consistency in the user's model.",

The new methods are intended to reduce the amount of space required to contain the hash-coded information from that associated with conventional methods. The reduction in space is accomplished by exploiting the possibility that a small fraction of errors of commission may be tolerable in some applications, in particular, applications in which a large amount of data is involved and a core resident hash area is consequently not feasible using conventional methods.

A number of options are available to give the user full control over the output format and to maximize the utility of NEATER2 as an aid during the early stages of development of a PL/I source deck. One option, USAGE, causes NEATER2 to insert into each logical unit of coding a statement which will case the number of times each one is executed to be recorded during execution.

Generations of cryptanalysts have expended untold man-years, thus far without success, attempting tode code them; vast armies of fortune hunters and treasure seekers have devoted Herculean labors to digging up the rolling hills of Virginia trying to locate the promised bonanza. \par The history of pertinent activities would fill volumes, yet serious students of cryptography have always had nagging doubts about the cyphers' authenticity. It has been alleged that the ``known solution'' to Cypher Number Two: 115, 73, 24, 818, 37, 52, 49, \ldots{} (``I have deposited in the County of Bedford about four miles from Buford's in an excavation or vault \ldots{}'') with the aid of an unsanitized version of the Declaration of Independence was merely a superb, imaginative, and grandiose hoax perpetrated ages ago for whatever reasons. Modern computer technology could obviously perform signature analyses the process of encoding itself so as to yield new clues and deeper insights into their construction. For the benefit of the uninitiated, the encoding method used in the second cypher employs a specified document whose words are simply numbered consecutively, and first letters of these words are sought out at random to match the letters of these words are sought out at random to match the letters of the clear text or message. \par The sequence of numbers corresponding to these matches is then written down as the final code. While primitive, the process has the advantage of relative security until the source document becomes known; at that moment the cypher can be decoded even by second graders. The work now completed with the help of our UNIVAC 1108 includes numerous analytical studies of the Beale cyphers and various types of simulations. \par For example, we have turned the entire process of simulated encoding by various schemes over to the machine and analyzed the signatures of these synthetic codes; we have also encoded various messages by hand, using different texts and a variety of methods to obtain their signatures. These simulations provide convincing evidence that the signatures are both process and data dependent; they indicate also very strongly that Mr. Beale's cyphers are for real and that it is merely a matter of time before someone finds the correct source document and locates the right vault in the common-wealth of Virginia.",

+ abstract = "An automatic learning capability has been developed and implemented for use with the MULTIPLE (MULTIpurpose Program that LEarns) heuristic tree-searching program, which is presently being applied to resolution theorem-proving in predicate calculus. MULTIPLE's proving program (PP) uses two evaluation functions to guide its search for a proof of whether or not a particular goal is achievable. Thirteen general features of predicate calculus clauses were created for use in the automatic learning of better evaluation functions for PP. A multiple regression program was used to produce optimal coefficients for linear polynomial functions in terms of the features.\par Also, automatic data-handling routines were written for passing data between the learning program and the proving program, and for analyzing and summarizing results. Data was generally collected for learning (regression analysis) from the experience of PP. A number of experiments were performed to test the effectiveness and generality of the learning program. Results showed that the learning produced dramatic improvements in the solutions to problems which were in the same domain as those used for collection learning data. Learning was also shown to generalize successfully to domains other than those used for data collection. Another experiment demonstrated that the learning program could simultaneously improve performance on problems in a specific domain and on problems in a variety of domains. Some variations of the learning program were also tested.",

The analysis does not assume uniformly distributed branching ratios, and therefore is applicable to a family of sorting algorithms discussed by Hoare, Singleton, and van Emden. \par The solution to the integral equation indicates that using more advanced algorithms in the family makes only minor reductions in the expected sorting effort, but substantially reduces the variance in sorting effort. Statistical tests of the values of several thousand trees containing up to 10,000 points have given first, second, and third moments of the value distribution function in satisfactory agreement with the moments computed from the generating function. The empirical tests, as well as the analytical results, are in agreement with previously published results for the first moment in the cases of uniform and nonuniform distribution of branching ratio, and for the second moment in the case of uniform distribution of branching ratio.",

In this paper the authors suggest that SPR be viewed as a one-person game played against nature (chance). Virtually all the powerful techniques developed for searching two-person, strictly competitive game trees can easily be incorporated either directly or by analogy into SPR procedures. \par In particular, one can incorporate the ``mini average backing-up procedure'' and the ``gamma procedure,'' which are the analogues of the ``minimax backing-up procedure'' and the ``alpha-beta procedure,'' respectively. \par Some computer simulated experiments in character recognition are presented.

If this particular area is full, then the entry will be placed into the slower second-level store, even though other areas in the first-level store may have space available. Given that N entries have been filed in the entire hierarchy, an expression is derived for the expected number of entries filed in the first-level store. This expression gives a measure of how effectively the first-level store is being used.

Each of them corresponds to two circular permutations which mirror-image each other, and is generated successively by a number system covering $3*4*\ldots*(n-1)$ sets of edges. Every set of edges $\{E[k]\}, 1 <= E[k] <= k, 3 <= k <= (n-1)$ is determined recursively by constructing a Hamiltonian circuit with $k$ vertices from a Hamiltonian circuit with $k-1$ vertices, starting with the Hamiltonian circuit of 3 vertices. The basic operation consists of transposition of a pair of adjacent vertices where the position of the pair in the permutation is determined by $\{E[k]\}$. Two algorithms treating the same example for five vertices are presented. It is very easy to derive all possible n! permutations from the $.5(n - 1 )!$ rosary permutations be cycling the permutations and by taking them in the reverse order-procedures which can be performed fairly efficiently by computer.",

First some standard terminology is introduced. Then the input buffer allocation method is described, followed by an analysis of the improvement to be expected over more conventional allocation. This analysis makes use of a particular distribution function. An analysis of a completely different distribution is given which yields similar results. This suggests that the results do not depend on a particular distribution function. An optimum output buffer size is also determined. It is concluded that this buffering allocation can significantly reduce the time of merge sorting on movable arm disks when the input data are not random, and that this output buffer allocation should be used whether the data is random or not.",

In particular, subexpressions should be executed in order of decreasing memory and processor time requirements. This observation is valid for configurations ranging from a uniprocessor with an unbuffered main memory to multiprocessor with a ``cache'' buffer memory.

The logic of this algorithm is rather complicated; hence, several other new dispersion algorithms with more straightforward logic are presented. Of the simple dispersion algorithms discussed, the Horizontal is best. It does approximately one-fourth to one and one-half percent less reading and writing than most algorithms in use today. An additional two and one-fourth to three percent improvement can be achieved by utilizing the Modified Optimum Algorithm. This algorithm is relatively straightforward, but it requires a fairly close estimate of the total number of unit strings before the dispersion begins.",

Problems regarding merging and disconnection of patterns during the process as well as the determination of the maximum number of steps necessary to obtain a single isolated element from a pattern, are reviewed and discussed.

This paper describes a polygon comparison scheme in which the relationships of two polygons can be classified into tree types, and also discusses how the relationship is changed for each pair of polygons under rotation about some axis. A rotation table is defined for each pair of polygons, which remains fixed as long as rotation is about one axis and provides a means of rapidly determining the visible and hidden line relationship between two polygons. \par Additional work must be done to extend this approach to simultaneous rotation about several axes.",

The high cost of these cosine transformations has been a serious drawback in using Clenshaw-Curtis quadrature. \par Two other problems related to the cosine transformation have also been trouble some. First, the conventional computation of the cosine transformation by recurrence relation is numerically unstable, particularly at the low frequencies which have the largest effect upon the integral. Second, in case the automatic scheme should require refinement of the sampling, storage is required to save the integrand values after the cosine transformation is computed. This second part of the paper shows how the cosine transformation can be computed by a modification of the fast Fourier transform and all three problems overcome. The modification is also applicable in other circumstances requiring cosine or sine transformations, such as polynomial interpolation through the Chebyshev points.",

There is a great deal of theoretical interest in Algol 68 and in extensible languages, but so far at least they have had little practical impact. Problem-oriented languages may very well become the most important language development area in the next five to ten years.\par In the operating system area all major computer manufacturers set out to produce very ambitious multiprogramming systems, and they all ran into similar problems. A number of university projects,though not directly comparable to those of the manufacturers, have contributed greatly to a better understanding of operating system principles. Important trends include the increased interest in the development of system measurement and evaluation techniques,and increased use of microprogramming for some programming system functions.",

The algorithm reduces the generalized problem to an ordinary eigenvalue problem for a symmetric band matrix C whose bandwidth is the same as A and B. The algorithm is similar to those of Rutishauser and Schwartz for the reduction of symmetric matrices to band form. The calculation of C requires order N**2m operation. The round-off error in the calculation of C is of the same order as the sum of the errors at each of the n/m steps of the algorithm, the latter errors being largely determined by the condition of B with respect to inversion.",

This system is based on a simple, high level language which is used to describe the evolving system at all stages of its development. The source language description is used as direct input to performance analysis and simulation routines. using the performance information obtained from these routines as feedback, the problems which adversely affect performance are detected early enough so that they can be corrected without costly major reimplementation of the proposed system.",

This freedom simplified both incremental compilation and the system's addressing structure, and centralized the communication mechanisms enabling the construction of hierarchical subsystems. It also suggested an important new concept for operating systems: separation of the scheduling from the maintenance functions in resource allocation. This separation enables incorporation of new scheduling algorithms (decision of what to do) without endangering the system integration (correctly performing the scheduling decisions).",

For the most part this assistance is implicit and is provided automatically by the compilers. The most remarkable characteristic of PL/C is its perseverance --- it completes translation of every program submitted and continues execution until a user-established error limit is reached. This requires that the compiler repair errors encountered during both translation and execution, and the design of PL/C is dominated by this consideration. PL/C also introduces several explicit user-controlled facilities for program testing. To accommodate these extensions to PL/I without abandoning compatibility with the IBM compiler, PL/C permits ``pseudo comments'' --- constructions whose contents can optionally be considered either source text or comment. In spite of the diagnostic effort PL/C is a fast and efficient processor. It effectively demonstrates that compilers can provide better diagnostic assistance than is customarily offered, even when a sophisticated source language is employed, and that this assistance need not be prohibitively costly.",

Recent research in time-sharing paging systems has developed the working set model for program behavior, and a resource allocation strategy based on this model has been proposed. Two implementations along these principles have been reported, but it seems that in neither case have further results been announced. This report discusses the design and implementation of a dispatcher based on the working set principle, presents data to permit analysis of its behavior, and indicates future directions of research on methods of controlling a computer system.",

Because dominoes is a game of incomplete information, the program uses somewhat different principles of artificial intelligence from those used in programs for games of complete information, such as checkers, chess, and go. The program was constructed to use a ``strategy signature table'' which classifies board situations through the interactions of game parameters. Each entry in the table contains adaptively determined weights indicating the advisability of various strategies. Once chosen, a strategy then employs probability analysis and linear polynomial evaluation to choose a move. Our program wins approximately two-thirds of its games in tournament situations, and has defeated championship players.",

It is thus more general than the previously published heuristic algorithms.

As a practical application of such a model this paper considers the design of a novel tree search scheme based on a bit vector representation of data and shows that essentially the same algorithm can be used to design either an ideal search tree or a bit-vector tree.

The dynamic verification of operating system decisions is used on the PRIME system being designed and constructed at the University of California, Berkeley. PRIME is an experimental time-sharing system which is to have the properties of continuous availability, data privacy, and cost effectiveness. The technique of dynamic verification allows the construction of an operating system which does not make certain decisions improperly even in the presence of a single hardware or software fault. Furthermore, multiple faults lead to unreliable operation only if the faults happen to reinforce each other. On PRIME, dynamic verification is used to ensure that one user's information cannot become available to another user gratuitously even in the presence of a single hardware or software fault.",

The PGS is a FORTRAN-coded program that accepts a translation grammar as input and constructs from it a compact, machine-coded compiler. In the input translation grammar, each BNF syntactic rule corresponds to a (possibly empty) ``code generator'' realizable as an assembly language, FORTRAN or Algol, subroutine that is called whenever that syntactic rule is applied in the parse of a program. Typical one-pass compilers constructed by the PGS translate source programs at speeds approaching 14,000 cards per minute. For an XPL compiler, the parser program and its tables currently occupy 288 words of 60-bit core memory of which 140 words are parsing table entries and 82 words are links to code generators.",

Because of the list processing procedures used, only a single pass through the XY display file is required when generating the binary image and only a slight increase in execution time over the fully buffered core results.

It is proved that the diagonals of the LU decomposition converges when floating-point precision. It is also proved that the computed LU decomposition converges when floating-point arithmetic is used and that the limits of the LU diagonals using floating point are roughly within machine precision of the limits using real arithmetic. This fact is exploited to reduce the number of floating-point operations required to solve a linear system from $8n-7$ to $5n+2k-3$, where $k$ is much less than $n$, the order of the matrix. If the elements of the subdiagonals and superdiagonals are 1, then only $4n+2k-3$ operations are needed. The entire LU decomposition takes $k$ words of storage, and considerable savings in array subscripting are achieved. Upper and lower bounds on $k$ are obtained in terms of the ratio of the coefficient matrix diagonal constants and parameters of the floating-point number system. Various generalizations of these results are discussed.",

Consider the class of sparse matrices which can be tridiagonalized using only row and corresponding column permutations. The advantages of using such a transformation include the absence of round-off errors and improved computation time when compared with standard transformations. \par A graph theoretic algorithm which examines an arbitrary $n \times n$ matrix and determines whether or not it can be permuted into tridiagonal form is given. The algorithm requires no arithmetic while the number of comparisons, the number of assignments, and the number of increments are linear in $n$. This compares very favorably with standard transformation methods. \par If the matrix is permutable into tridiagonal form, the algorithm gives the explicit tridiagonal form. Otherwise, early rejection will occur.",

Results obtained from the implementations show that the noninteractive algorithms can significantly reduce display file storage requirements at little cost in execution time over that of a conventional raster display. The interactive algorithm improve response time and reduce storage requirements.",

All aspects of the system, including all relevant code and data bases, may be known by anyone attempting to intrude. The scheme is based on using a function H which the would-be intruder is unable to invert. This function is applied to the user's password and the result compared to a table entry, a match being interpreted as authentication of the user. The intruder may know all about H and have access to the table, but he can penetrate the system only if he can invert H to determine an input that produces a given output.

The new algorithm is a step-by-step procedure for solving the initial value problem in ordinary differential equations. It is designed to approximate poles of small integer order in the solutions of the differential equations by continued fractions obtained by manipulating the sums of truncated Taylor series expansions. The new method is compared with Gragg-Bulirsh-Stoer, and the Taylor series method. \par The Taylor series method and the new method are shown to be superior in speed and accuracy, while the new method is shown to be most superior when the solution is required near a singularity. The new method can finally be seen to pass automatically through singularities where all the other methods which are discussed will have failed.",

There is no simple method for generating gamma random variates with non-integral shape parameters. A common procedure is to approximately generate such random variables by the use of the so-called probability switch method. Another procedure, which is exact, is due to Joehnk. This paper presents a rejection method for exactly generating gamma random variables when alpha is greater than 1. The efficiency of the rejection method is shown to be better than the efficiency of M. D. Joehnk's method. The paper concludes that when alpha is non-integral, the following mix of procedures yields the best combination of accuracy and efficiency: (1) when alpha is less than 1, use Joehnk's method; (2) when 1 is less than alpha and alpha is less than 5, use the rejection method; (3) when alpha is greater than 5, use the probability switch method.",

An obvious lower limit to this number is the size of the largest strongly connected subgraph. Kirchgassner proved that an upper limit is this size plus one. One logical extension of the previous work is the introduction of variable length examinations where $W(I)$ is the number of periods for exam $I$. The object of this paper is to generalize the definition of largest strongly connected subgraph to include the weighting of nodes, to present an approximate algorithm which usually finds the largest strongly connected subgraph, and to discuss the application of this algorithm to the solution of school scheduling and exam scheduling problems.",

Experience indicates that the language can be learned in an hour or so, for it has few rules and fewer exceptions. For typical expressions, the size and font changes, positioning, line drawing, and the like necessary to print according to mathematical conventions are all done automatically. For example, the input {\tt sum from i=0 to infinity x sub i=pi over 2} produces $\sum_{i=0}^\infty x_i = \pi/2$. The syntax of the language is specified by a small context-free grammar; a compiler-compiler is used to make a compiler that translates this language into typesetting commands. Output maybe produced on either a phototypesetter or on a terminal with forward and reverse half-line motions. The system interfaces directly with text formatting programs, so mixtures of text and mathematics may be handled simply. This paper was typeset by the authors using the system described.",

This problem may be attributed in part to difficulties such as slow stochastic convergence. However, an additional problem lies in the fact that a significant amount of bookkeeping time is required to keep future events in their proper sequence. This paper presents a method for significantly reducing the time spent scanning future event lists in discrete event simulations. \par There models are presented, all of which improve in effectiveness as the events-list scan problem becomes more burdensome.",

For exponential and hyperexponential distributions of requests, first-fit outperformed best-fit; but for normal and uniform distributions, and for exponential distributions distorted in various ways, best-fit outperformed first-fit. It is hypothesized that when first-fit outperforms best-fit, it does so because first-fit, by preferentially allocating toward one end of memory, encourages large blocks to grow at the other end. Sufficient contiguous space is thereby more likely to be available for relatively large requests. Results of simulation experiments supported this hypothesis and showed that the relative performance of first-fit and best-fit depends on the frequency of requests that are large compared to the average request. when the coefficient of variation of the request distribution is greater than or approximately equal to unity, first-fit outperformed best-fit.",

Complete procedures for garbage collection and for standard list processing primitives are presented and thoroughly explained. Particular attention is given to the problems of marking and relocating list cells while another processor may be operating on them. The primary aim throughout is to allow the list processor to run unimpeded while the other processor reclaims list storage. The more complex cases involving several list processors and one or more garbage collection processors are also briefly discussed.",

In the first case, it is shown that for every k there exists an O(n**k** plus **2) algorithm for testing the LR(k) property, where n is the size of the grammar in question. On the other hand, if both k and the subject grammar are problem parameters, then the complexity of the problem depends very strongly on the representation chosen for k. More specifically, it is shown that this problem is NP-complete when k is expressed in unary. When k is expressed in binary the problem is complete for nondeterministic exponential time.

Four new algorithms have the attribute that special cases occur every n(n minus 1) permutations. Two of the algorithms produce the next permutation with a single exchange of two marks. The other two algorithms infrequently exchange more than two marks, but the rules for generating the next permutation are very simple. Performance tests which have counted execution of assignment statements, comparisons, arithmetic operations, and subscripted array references have shown superiority of the new algorithms compared to Boothroyd's implementation of M.

The properties of an edge are embedded in a figure of merit and the edge detection problem becomes the problem of minimizing the given figure of merit. This problem can be represented as a shortest path problem on a graph and can be solved using well-known graph search algorithms. The relations between this representation of the minimization problem and a dynamic programming approach are discussed, showing that the graph search method can lead to substantial improvements in computing time. Moreover, if heuristic search methods are used, the computing time will depend on the amount of noise in the picture. Some experimental results are given; these show how various information about the shape of the contour of an object can be embedded in the figure of merit, thus allowing the extraction of contours from noisy pictures and the separation of touching objects.",

Algorithms for recovering discarded list structures in this manner are presented and analyzed to determine sufficient conditions under which the list processor never need to wait on the collector. These techniques are shown to require at most twice as much processing power as regular garbage collectors, if they are used efficiently. The average behavior of the program is shown to be very nearly equal to the worst-case performance, so that the sufficient conditions are also suitable for measuring the typical behavior of the algorithm.",

+ abstract = "By using an extension of traditional structure information, or a geometric hierarchy, five significant improvements to current techniques of computer picture production are possible. First, the range of complexity of an environment is greatly increased while the visible complexity of any given scene is kept within a fixed upper limit. Second, a meaningful way is provided to vary the amount of detail presented in a scene. Third, ``clipping'' becomes a very fast logarithmic search for the resolvable parts of the environment within the field of view. Fourth, frame to frame coherence and clipping define a graphical ``working set,'' or fraction of the total structure that should be present in primary store for immediate access by the visible surface algorithm. Finally, the geometric structure suggests a recursive descent, visible surface algorithm in which the computation time potentially grows linearly with the visible complexity of the scene.",

Each value of the parameter represents at most two points, and these may easily be distinguished.

The proposed attitude aims at retaining the purity of the nondeterministic formulation of search processes on one level (the attempt level), deferring the coordination of problem solving efforts to another (the choice level). The feasibility of recognizing these two levels is discussed, stressing that the structure to be managed at the choice level is a tree of contexts. The leaves are computational environments, each holding an alternative under inspection, while the other nodes are associated with choice points. According to the proposed programming style, a generative function is associated with each choice point, which expresses the desired choice strategy. The main advantage of this approach is the localization of the search strategies: Each nonterminal node of the tree keeps track of the state of the computation as it was when the choice point was last interrogated, holding at the same time the strategy to coordinate the available alternatives. Examples are given in term of ND-Lisp, an extension of Lisp designed and implemented according to these guidelines.",

During the search operation, the characters of pat are matched starting with the last character of pat. The information gained by starting the match at the end of the pattern often allows the algorithm to proceed in large jumps through the text being searched. Thus the algorithm has the unusual property that, in most cases, not all of the first i characters of string are inspected. The number of characters actually inspected (on the average) decreases as a function of the length of pat. For a random English pattern of length 5, the algorithm will typically inspect i/4 characters of string before finding a match at i. Furthermore, the algorithm has been implemented so that (on the average) fewer than i plus patlen machine instructions are executed. These conclusions are supported with empirical evidence and a theoretical analysis of the average behavior of the algorithm. The worst case behavior of the algorithm is linear in i plus patlen, assuming the availability of array space for tables linear in patlen plus the size of the alphabet.",

A new derivation is given, and it is shown that previous derivations make an assumption that may be violated frequently. On the basis of the simulation data and the derivation, it is hypothesized that the anomalous behavior results from the combined effects of systematic placement and the statistics of the release process. Additional simulations support this hypothesis. Systematic placement, which refers to the natural convention of always allocating storage requests against the same end of the free block selected by the allocation strategy, tends to order blocks within contiguous groups, according to their allocation time. The degree of anomalous behavior depends on the extent to which allocated blocks are released in the order of their allocation. For non-Markovian release processes, the extent of the correlation between allocation order and release order varies approximately inversely with the coefficient of variation of the memory residence time distribution. The simulations show that allocation efficiency depends strongly on the residence time distribution; efficiency decreases as the distribution's coefficient of variation increases. Some practical implications are briefly discussed.",

Given a set I of identifiers, two methods are presented for building, in a mechanical way, perfect hashing functions, i.e. functions transforming the elements of I into unique addresses. The first method, the ``quotient reduction'' method, is shown to be complete in the sense that for every set I the smallest table in which the elements of I can be stored and from which they can be retrieved by using a perfect hashing function constructed by this method can be found. However, for nonuniformly distributed sets, this method can give rather sparse tables. The second method, the ``remainder reduction'' method, is not complete in the above sense, but it seems to give minimal (or almost minimal) tables for every kind of set. The two techniques are applicable directly to small sets. Some methods to extend these results to larger sets are also presented. A rough comparison with ordinary hashing is given which shows that this method can be used conveniently in several practical applications.",

Embeddings of graphs are used to model the loss of proximity involved in such storage schemes, and an elementary proof that arrays cannot be stored as linear lists with bounded loss of proximity is presented. Average loss of proximity is then considered, and it is shown that arrays cannot be stored as linear lists with only bounded loss of average proximity, but can be so stored in binary trees. The former result implies, for instance, that row major order is an asymptotically optimal storage strategy for arrays.",

Since assignment, CALL, RETURN, and IF statements together account for 93 percent of all executable statements, special care is given to ensure that these statements can be implemented efficiently. A highly compact instruction encoding scheme is presented, which can reduce program size by a factor of 3. Unlike a Huffman code, which utilizes variable length fields, this method uses only fixed length (1-byte) op code and address fields. The most frequent instructions consist of a single 1-byte field. As a consequence, instruction decoding time is minimized, and the machine is efficient with respect to both space and time.",

For a ratio of 100:1, 10\slash 11 of a full cycle should be covered quickly and 1/11 should be covered slowly. As device manufacturers increase this ratio, the average latency for a block transfer will slowly decrease. Increasing the raw shift speed will of course directly reduce both the latency time and the block transfer time.",

It is shown that deletion of an arbitrary node of such a tree can be accomplished in O(log n) operations, where n is the number of nodes in the tree. Moreover the method is optimal in the sense that its complexity cannot be reduced in order of magnitude. This result, coupled with earlier results by D. S.

Since rerooting leaves assoc left bracket v, a right bracket invariant, for all variables v and all environments a, the programmer can have access to a rerooting primitive, shallow left bracket right bracket, which gives him dynamic control over whether accesses are shallow or deep, and which affects only the speed of execution of a program, not its semantics.",

The objective is to find a transformed digital picture of a given picture such that the sum of absolute errors between the gray level histogram of the transformed picture and that of a reference picture is minimized. This is equivalent to placing k1 linearly ordered objects of different sizes one by one into k2 linearly ordered boxes of assorted sizes, such that the accumulated error of space underpacked or overpacked in the boxes is minimized; the placement function is monotonic, which ensures a polynomial time solution to this problem. A tree search algorithm for optimal histogram matching is presented which has time complexity O(k1 multiplied by k2). If the monotone property is dropped, then the problem becomes NP-complete, even if it is restricted to k2 equals 2.",

A technique is described for constructing a detailed deterministic simulation model of a system. In the model a control stream replaces the instruction and data streams of the real system. Simulation of the system model yields the timing resource usage statistics needed for performance evaluation, without the necessity of emulating the system. As a case study, the implementation of a simulation of a model of the CPU-memory subsystem of the IBM 360\slash 191 is described. The results of evaluating some alternative system designs are discussed. The experiments reveal that, for the case study, the major bottlenecks in the system are the memory unit and the fixed point unit. Further, it appears that many of the sophisticated pipelining and buffering techniques implemented in the architecture of the IBM 360\slash 91 are of little value when high-speed (cache) memory is used, as in the IBM 360\slash 195.",

Automatic navigation using visible light or radar images requires exact alignment of such images with digital terrain models. In addition, automatic classification of terrain, using satellite imagery, requires such alignment to deal correctly with the effects of varying sun angle and surface slope. Even inspection techniques for certain industrial parts may be improved by this means. The required alignment is achieved by matching the real image with a synthetic image obtained from a surface model and known positions of the light sources. The synthetic image intensity is calculated using the reflectance map, a convenient way of describing surface reflection as a function of surface gradient. The technique is illustrated using LANDSAT images and digital terrain models.",

A split tree is a binary search tree each node of which contains two key values --- a node value which is a maximally frequent key in that subtree, and a split value which partitions the remaining keys (with respect to their lexical ordering) between the left and right subtrees. A median split tree (MST) uses the lexical median of a node's descendents as its split value to force the search tree to be perfectly balanced, achieving both a space efficient representation of the tree and high search speed. Unlike frequency ordered binary search trees, the cost of a successful search of an MST is log n bounded and very stable around minimal values. Further, an MST can be built for a given key ordering and set of frequencies in time n log n, as opposed to n**2 for an optimum binary search tree. A discussion of the application of MST's to dictionary lookup for English is presented, and the performance obtained is contrasted with that of other techniques.",

Furthermore, it cannot be used to produce good, quasioptimal solutions The branch-and-bound technique uses a good heuristic to direct the search, but is cluttered up by an enormous search space, since the number of solutions increases with the number of test variables according to a double exponential. In this paper authors suggest a heuristically guided top-down search algorithm which, like dynamic programming, recognizes identical subproblems but which can be used to find both optimal and quasioptimal solutions. A heuristic search method is introduced that combines the positive aspects of the above two techniques.

An example is given which shows how to employ algebraic axioms at successive levels of implementation. First, it is shown how the use of algebraic axiomatizations can simplify the process of proving the correctness of an implementation of an abstract data type. Second, semi-automatic tools are described which can be used both to automate such proofs of correctness and to derive an immediate implementation from the axioms. This implementation allows for limited testing of programs at design time, before a conventional implementation is accomplished.",

Since a central hyperplane does not favor one class or the other, it should have a lower error rate in classifying new points and is therefore better than a noncentral hyperplane. Six algorithms for finding central hyperplanes are tested on three data sets. Although frequently used in practice, the modified relaxation algorithm is very poor. Three algorithms which are defined in the paper are found to be quite good.",

Current programming language concepts will not be adequate for building and maintaining systems of the complexity called for by the tasks we attempt. Just as high level languages enabled the programmer to escape from the intricacies of a machine's order code, higher level programming systems can provide the means to understand and manipulate complex systems and components. In order to develop such systems, we need to shift our attention away from the detailed specification of algorithms, towards the description of the properties of the packages and objects with which we build. This paper analyzes some of the shortcomings of programming languages as they now exist, and lays out some possible directions for future research.",

This also makes possible the derivation of an asymptotically better bound for multiplication of matrices given in row-oriented form by adapting the technique of Strassen to the reorganized data. The reorganization\slash block multiplication scheme is shown to be advantageous for matrices and pages of realistic size; the Strassen adaptation is not. The former scheme is also shown to be advantageous even if the transpose of one of the matrices is available at no additional cost.",

Two parameterized algorithms which partition the main memory between two classes of jobs are considered.

Applying a decomposition approach and treating the closed system as a single server, the response times in an open system with external arrivals are studied. The object is to investigate the effect of the memory allocation parameters on the expected response times under the two algorithms. Numerical solutions and economical lower bounds for the expected response times as functions of the control parameters are obtained.

The algorithm operates in time $O(\log n)$, where $n$ is the number of nodes in the tree. This represents an improvement over the best previous ly known insertion algorithms of Hirschberg and Kosaraju, which require time $O(\log 2n)$. Moreover, the $O(\log n)$ complexity is optimal. Earlier results have shown that deletion in such a structure can also be performed in $O(\log n)$ time. Thus the result of this paper gives a negative answer to the question of whether such trees should be the first examples of their kind, where deletion has a smaller time complexity than insertion. Furthermore, it can now be concluded that insertion, deletion, and retrieval in OSHB trees can be performed in the same time as the corresponding operations for the more general AVL trees, to within a constant factor. However, the insertion and deletion algorithms for OSHB trees appear much more complicated than the corresponding algorithms for AVL trees.",

For a graph of e edges, the algorithm has a worst-case time bound of 0(e log e) function operations. It is also shown that in programming terms, the number of operations is proportional to e plus the number of exits from program loops. Consequently a restriction to one-entry one-exit control structures guarantees linearity. The algorithm can be extended to yet larger classes of function spaces and graphs by relaxing the time bound. Examples are given of code improvement problems which can be solved using the algorithm.",

Several algorithms for determining the number of components in the graph associated with a particular set of elements are constructed and compared. When the classification process operates on independently-drawn samples of $n$ distinct elements from a population, the expected number of components is shown to be obtainable recursively for a class of problems called separable; in all cases, estimates are available to reach any desired level of accuracy. Clustering models in Euclidean space are analyzed in detail and asymptotic formulas obtained to complement experiments. Conjectures concerning the general behavior of the expected number of components are presented also. Finally, several computational tools of general interest are improved significantly.",
