OPS5 definition
<language> A programming language for rule-based production
systems. A rule consists of pre-condition(s) and a resulting
action.
The system checks its working memory to see if there are
rules whose pre-conditions are satisfied, if so, the action in
one selected satisfied rule is executed.
There is a public domain implementation of an OPS5
interpreter written by Charles L. Forgy <forgy@cs.cmu.edu>
in 1977. It was first implemented in Lisp and later in
BLISS. It was also ported to Common Lisp by George Wood
and Jim Kowalski.
CLIPS is a language for writing expert systems, with some
of the capabilities of OPS5.
