The article presents information on the Symposium on Symbolic and Algebraic Manipulation held on March 29-31, at the Sheraton Park Hotel, Washington D.C. The symposium was sponsored by the Association for Computing Machinery's (ACM) Special Interest Committee on Symbolic and Algebraic Manipulation, and held under the general chairmanship of Jean E. Sammet. A registered attendance of 450 included international visitors such as M. Wilkes of Cambridge, England and A. Caracciolo of Pisa, Italy. The meeting was opened by ACM Vice- President H.S. Bright, followed by Jean Sammet who surveyed the present state of the art in this area. There were ten informal discussion sessions during the first two evenings and two online demonstrations. The most heavily attended sessions were on LISP-2 and on the "Mathematics and Metamathematics" of algebraic manipulation, but the other sessions, such as on graphical languages, drew large numbers of interested participants. This conference made clear that many independent groups were making significant progress in fabricating techniques for a new tool in computer science.

The article presents information on various chapters of the Association for Computing Machinery (ACM) across the U.S. The Greater Rio Grande Chapter of ACM has recently extracted from its files a list of the titles of all technical papers presented at Chapter meetings since its inception in 1957. Using a program developed by D.K. Robbins of Sandia Corp., a KWIC-type listing of permuted titles of these papers has been made. This listing has been distributed to all members of the Chapter. Topics and speakers at ACM Chapters across the U.S. indicate the current trends of interest in computer science and data processing. The ACM Tidewater Chapter is sponsoring this spring a professional development course on "Real-Time Computing." The course is given by the Chapter's professional development chairman, Cecil Frost, who is applications staff specialist for Control Data Corp. At its April 21, 1966 meeting, the Westchester-Fairfield Chapter heard William Orchard-Hays speak on "Linear Programming of Computational Techniques."

This article focuses on research articles related to computer applications. Poisson series of three variables are manageable symbolically through a set of formal subroutines written partially in the IBM 7094 machine language, but to be called in the FORTRAN language for use in FORTRAN programs. In the article "Symbolic Manipulation of Poisson Series," by J. Danby, A. Deprit and A. Rom, an effort has been made to supply those operations which are most required by celestial mechanics. The routines are entirely self-contained subroutines and require only standard FORTRAN input/output units 5 and 6; they are designed to avoid waste and overflow of core storage space. In the article "A FORMAC Program for the Solution of Linear Boundary and Initial Value Problems," by E. Cuthill, a computer program is described which has been developed for obtaining approximate solutions to linear initial and boundary-value problems involving differential equations. The article further focuses on the article "Computation of Algebraic Properties of Elementary Particle Reactions Using a Digital Computer," by A. Hearn.

This article presents information on two articles related to computer science. These are: "PM: A System for Polynomial Manipulation," by G. Collins; and "Experience With FORMAC Algorithm Design," by R. Tobey.

This article presents information on several articles related to computer science. In the article "Application of LISP to Sequence Prediction," by Paul W. Abrahams, a LISP program that analyzes sequences of letters and numbers is described. The program takes as input a sequence such as A C E G I and so on and produces as output the next element of the sequence, in this ease K. The program does this by creating a LISP program that will generate the nth element of the sequence, given n, and then executing this program with the length of the given sequence plus one as argument. In the article "Models for Mathematical Systems," by Alfred H. Morris, a program, written for the IBM 7090, which defines a model for a finite collection of associative algebras for the computer, is described and illustrated. The program contains a structure broad enough in scope to allow one to perform operations on such diverse mathematical concepts as differential equations, infinite series and differential forms in a simple yet comprehensive manner, while also serving in a foundation upon which a variety of higher level symbol manipulation languages can be developed.

This article focuses on several articles related to computer programs for algebraic simplification. In the article "MANIP: A Computer System for Algebra and Analytic Differentiation," by Bernice Bender, a mathematical expression to be operated upon is written in FORTRAN-like notation and stored in the computer as a string of BCD characters with all blanks removed. It may be as complicated as desired so long as the entire expression does not exceed 5000 characters. The problem of performing algebraic operations and obtaining analytic derivatives was translated into that of identifying and manipulating character sequences. Programs which resulted were written in FORTRAN IV for a CDC 3600 computer and are discussed in detail. The goal of the computer program mentioned in the article "An On-Line Program for Non-Numerical Algebra," by Knut Korsvold, is to make a step towards the design of an automated mathematical assistant. Some requirements for such a program are: it must be easy to access, and that the result must be obtained in a reasonably short time. Accordingly the program is written for a time-shared computer.

This article focuses on several articles related to electronic methods in symbol manipulation. The author's viewpoint in the article "Operators for Manipulating Language Structures," by Barry Lawrence Wolman, is that all aspects of the engineering design problem are treated initially as statements in some appropriate predefined languages. These problem description statements are converted by a table-driven language translator into an intermediate form, called the first-pass structure, which models the syntax and semantics of the original statement. The characteristics of the languages used to describe the problem may be specified and altered via a subsystem of CADET. All of the processes desired in the CADET System can be considered to be the result of some operator applied to a first-pass structure so as to transform the meaning of the statement into a suitable form. The semantic sequencing information contained in the first-pass structure enables operators defined for atomic forms to be applied to arbitrarily complex structures in a uniform manner. The article further focuses on "Convert," by A. Guzman and H. McIntosh.

A brief description is given of the implementation technique for the replacement rule of the AMBIT programming language. The algorithm for the "AMBIT scan" and an example of its application are given. The algorithm is applicable to other members of the family of string transformation languages of which AMBIT is a member, and it provides a rationale for the design of the AMBIT language. [ABSTRACT FROM AUTHOR]

Various facets of the design and implementation of mathematical expression manipulation algorithms are discussed. Concrete examples are provided by the FORMAC EXPAND and differentiation algorithms, a basic FORMAC utility routine, and an experiment in the extraction of the skeletal structure of on expression. One recurrent theme is the need to avoid excessive intermediate expression swell in order to minimize core storage requirements. Although many details from the FORMAC implementation are presented, an attempt is made to stress principles and ideas of general relevance in the design of algorithms for manipulating mathematical expressions. [ABSTRACT FROM AUTHOR]

A programming language is described which is applicable to problems conveniently described by transformation rules. By this is meant that patterns may be prescribed, each being associated with a skeleton, so that a series of such pairs may be searched until a pattern is found which matches an expression to be transformed. The conditions for a match are governed by a code which also allows subexpressions to be identified and eventually substituted into the corresponding skeleton. The primitive patterns and primitive skeletons are described, as well as the principles which allow their elaboration into more complicated patterns and skeletons. The advantages of the language are that it allows one to apply transformation rules to lists and arrays as easily as strings, that both patterns and skeletons may be defined recursively, and that as a consequence programs may be stated quite concisely.

Bell Telephone Laboratories' Low-Level Linked List Language L6 (pronounced "L-six") is a new programming language for list structure manipulations. It contains many of the facilities which underlie such list processors as IPL, LISP, COMIT and SNOBOL, but permits the user to get much closer to machine code in order to write faster-running programs, to use storage more efficiently and to build a wider variety of linked data structures.
