**Computational Aids for Determining the Minimal Form of a Truth Function**

Ronald Prather

Pages: 299-310

DOI: 10.1145/321043.321044

The literature concerned with methods for finding the minimal form of a truth function is, by now, quite extensive. This article extends this knowledge by introducing an algorithm whereby all calculations are performed on decimal numbers...

**Connective Properties Preserved in Minimal State Machines**

Seymour Ginsburg

Pages: 311-325

DOI: 10.1145/321043.321045

**Integer Programming Formulation of Traveling Salesman Problems**

C. E. Miller, A. W. Tucker, R. A. Zemlin

Pages: 326-329

DOI: 10.1145/321043.321046

It has been observed by many people that a striking number of quite diverse mathematical problems can be formulated as problems in integer programming, that is, linear programming problems in which some or all of the variables are required to...

**Techniques for Enumerating Veblen-Wedderburn Systems**

Erwin Kleinfeld

Pages: 330-337

DOI: 10.1145/321043.321047

**On Pre-Conditioning of Matrices**

E. E. Osborne

Pages: 338-345

**A Note on a Method of Computing the Gamma Function**

N. L. Gordon, A. H. Flasterstein

Pages: 387-388

DOI: 10.1145/321043.321050

Numerous formulas are available for the computation of the Gamma function [1, 2]. The purpose of this note is to indicate the value of a well-known method that is easily extended for higher accuracy requirements.
Using the recursion...

**Computer Time for Address Calculation Sorting**

Ivan Flores

Pages: 389-409

DOI: 10.1145/321043.321051

For each item to be sorted by address calculation, a location in the file is determined by a linear formula. It is placed there if the location is empty. If there is an item at the specified location, a search is made to find the closest empty...
