Research and Advances An ACM state-of-the-art paper
Use of linear programming models has grown so extensively in recent years that the whole concept for organizing a computer code has undergone a radical change. It no…

Symbol manipulation in FORTRAN: SASP I subroutines
A set of subroutines for use in FORTRAN are described whose purpose is to synthesize output strings from (i) input strings which have been analysed by the SHADOW general…

Design and implementation of a general-purpose input routine
A general-purpose input routine is discussed and advocated for FORTRAN. The philosophy of such programs is examined and exemplified.
Research and Advances Techniques
Reducing truncation errors by programming
In accumulating a sum such as in a numerical integration with a large number of intervals, the sum itself becomes much larger than the individual addends. This may…
Research and Advances Techniques
The list concept as originally proposed by Newell, Simon and Shaw specified single computer words as elements of a list. This report describes the use of two or more…

A parts breakdown technique using list structures
List structured parts breakdown is proposed and discussed. Implementation facts are presented on operating program using these techniques.

Numerical solution of nonlinear two-point boundary problems by finite difference methods
Solution of nonlinear two-point boundary-value problems is often an extremely difficult task. Quite apart from questions of reality and uniqueness, there is no…

Approximate solution of axially symmetric problems
A variety of physical problems in such diverse fields as electrostatic field theory, heat and ideal fluid flow, and stress concentration theory reduce, under the…

Generation of test matrices by similarity transformations
A method for obtaining test matrices with a prescribed distribution of characteristic roots is given. The process consists of using particularly simple similarity…
