- -- Abstract :
- ----------------:
- -- 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. Many improvements would
- --be possible if more time permitted my working on this.
