Report on proposed American standard flowchart symbols for information processing
This paper presents the essential contents of the Proposed American Standard Flowchart Symbols for Information Processing. This is the first proposed standard prepared by…
Character addressable, variable field computers permit ready establishment and manipulation of variable width stacks. Single machine commands may push variable field…
An experiment in automatic verification of programs
How effective is a compiler at replacing explicit verification, and what is the cost of this technique?
Partioning algorithms for finite sets
The partitions of a set with n elements are represented by certain n-tuples of positive integers. Algorithms are described which generate without repetitions the n-tuples…
A contour-map program for x-ray crystallography
A FORTRAN program is described for use with the IBM 7090 system and an x, y-plotter to produce a contour map. A matrix of points evenly spaced in each dimension is…
DATA-DIAL: two-way communication with computers from ordinary dial telphones
An operating system is described which allows users to call up a remotely located computer from ordinary dial telephones. No special hardware or connections are required…
An automatic data acquisition and inquiry system using disk files
Lockheed Missiles and Space Company has installed a large-scale Automatic Data Acquisition (ADA) system which ties together the Company's manufacturing facilities located…
Use of the disk file on stretch
The paper begins by briefly describing the Stretch (IBM 7030) computer with special emphasis given to the organization and operation of its input-output equipment.…
A comparison of disks and tapes
The principal characteristics of current magnetic disks and tape units are summarized and compared. Some of the characteristics of disk files are illustrated in a sorting…
An extension of Fibonaccian search to several variables
A technique which uses Fibonaccion search concepts has been developed to solve optimization problems involving unimodal functions of several variables. The technique has…
Computation’s development critical to our society
The ACM's growth continues: we are now at 13,000 members; expenses also grow. Our professional membership does not spring from a uniformly trained group as in mathematics…
