TMYCIN Expert System Shell

TMYCIN is an expert system shell modeled after the EMYCIN shell that was developed at Stanford. It is especially useful for student exercises, although real expert systems have been written using it.

TMYCIN is written in Common Lisp and is fairly small (11 pages of code). It should run under any implementation of Common Lisp.

You can download Gnu Common Lisp for Linux or for Windows.

Two example expert systems are furnished: a very small set of rules for identifying rocks, and a small set of rules for identifying Texas snakes.
