Solution of Eigenvalue problems with approximately known Eigenvectors
It is often desired to solve eigenvalue problems of the type (A - &lgr;1)C = 0 or (A - &lgr;B)C = 0 repeatedly for similar values of the matrix elements Aij, where A and…
A modified inversion procedure for product form of the inverse linear programming codes
This paper describes a new algorithm for the selection of the pivot row in matrix inversion when using the product form of the inverse. This algorithm has been developed…
On translation of Boolean expressions
A program which translates an algorithmic language such as ALGOL into the machine language of an electronic computer performs the following functions:…
A machine program for theorem-proving
The programming of a proof procedure is discussed in connection with trial runs and possible improvements.
Nonlinear regression and the solution of simultaneous equations
If one has a set of observables (z1, ··· , zm) which are bound in a relation with certain parameters (a1, ··· , an) by an…
The logic of English grammar is being investigated by a process of approximative logical synthesis. Beginning with a kernel language which is an alphabetically spelled…
Triangular walk pattern for the down-hill method of solving a transcendental equation
The down-hill method by Ward is a numerical method for determining a complex root of ƒ(z) = 0 and suitable for machine computation [1]. It is based on a theorem that…
Digital synthesis of correlated stationary noise
In this note we propose a method of generating stationary noise with a prescribed auto-covariance function by digital methods. The need for such a technique often arises…
Person-matching by electronic methods
Record linkage in the updating of files is accomplished in many establishments through the use of a preassigned number, such as payroll number, customer number, or social…
A computer method for radiation treatment planning
Automatic computation methods were first developed and applied to the problem of radiation therapy treatment planning by the Physics staff at Memorial Hospital and…
