ABSTRACT

Expert System

EXPERT is a backward chaining or goal driven expert system. It is based on two articles, first Sept 1981 BYTE (Duda and Gaschnig) published the expert system in BASIC skirting the use of recursion, second Jan/Feb 85 issue of JOURNAL OF PASCAL,ADA, & MODULA-2 (Darrell Morgeson) published in Modula-2 with recursion implemented. The listing had one logic error which caused pointer explosion on the last hypothesis in the GETRULE routine. This implementation follows the MODULA-2 design completely and was not designed from the ground up in Ada.
