Features
The assignment problem is formulated and briefly discussed. An efficient algorithm for its solution is presented in ALGOL code. An empirical relation between solution…
Compilation for two computers with NELIAC
NELIAC, a compiler based on ALGOL, was developed at the U. S. Navy Electronics Laboratory, San Diego, California, as a “bootstrap” compiler for the Remington…
Least squares fitting of a great circle through points on a sphere
version of itself which, running as a COUNTESS program, generated machine code for the Control Data Corporation CDC-1604 computer. This second compiler was then used to…
Over all computation control and labelling
The primary function of computer installation is (as everyone knows) to solve useful problems. The programs that accomplish such solutions are called production programs,…
A simple technique for coding differential equations
A computer program that will solve an arbitrary system of first-order differential equations according to some conventional numerical method may be considered to have two…
An estimation of the relative efficiency of two internal sorting methods
This report concerns the IBM 705, models I and II. It is a study of the machine time required by two internal sorting methods, the conventional two-way merge, and a form…
On a recent motor trip through Mexico, the writer came across an adding device which was referred to as a sumador chino (Chinese adder). A survey of the more available…
Character scanning on the IBM 7070
One general requirement in the construction of symbol manipulators and automatic programming systems is the need to scan a line of information, usually from left to…
