Abstract

This paper presents the basis for such a system. A variant of the algorithm outlined here has been coded and tested; however time limitations prevent the detailed discussion of the full system. We present here a simplified version with a few remarks on extensions. The system presented here is believed to be unique. Bobrow1 has proposed a system wherein a set of simultaneous equations are stored and a list of “wanted” variables presented. The return is a list of values of the “wanted” variables; either numeric or algebraic values. This differs from our system, where the output is an executable program for calculating “wanted” variables, wherein specific values of variables are not entered until run time. Veronis2 devised a scheme for using the computer to write the repetitive FORTRAN statements required for a program to solve simultaneous ordinary differential equations. Again, this differs considerably from the system presented here.
