Abstract
DEMON is a system designed to solve problems involving ordinary differential equations as quickly as possible. It accepts differential equations in the D — notation (that is, y' = y + y' is expressed as D2Y = Y + DY), and generates a FORTRAN programme to solve the problem. A means is provided for solving boundary equation problems. New integration methods may be defined to DEMON together with the problem. These methods may range from Predictor — Corrector to Gaussian quadrature. Non-self-starting methods are automatically started. The DEMON programme has been written in COBOL and should be suitable for any large machine. At the A.A.E.C. Research Establishment the DEMON system is working on a 32K IBM - 7040, where the time taken from completely defining the problem to receiving the results may be as short as ten minutes.
