ops5 การใช้

• Prolog, OPS5 and Mercury are examples of fifth-generation languages.
• OPS5 may be viewed as a full-fledged programming language for production system programming.
• Production rules in OPS5 apply to all instances of data structures that match conditions and conform to variable bindings.
• One of the first and most popular forward chaining engines was OPS5 which used the Rete algorithm to optimize the efficiency of rule firing.
• "' DEC OPS5 "'is an extended implementation of the OPS5 language definition, developed for use with the VMS, RISC ULTRIX, and DEC OSF / 1 operating systems.

• Despite the availability of Lisp, Prolog and Inference engine shells such as OPS5, GARVAN-ES1 was written in plain old  C and used macro s to encode  English like rules.
• The latter is illustrated by the Charles L . Forgy in 1983, which is used in a series of production systems, called OPS and originally developed at Carnegie Mellon University culminating in OPS5 in the early eighties.
• OPS5 uses a forward chaining inference engine; programs execute by scanning " working memory elements " ( which are vaguely object-like, with classes and attributes ) looking for matches with the rules in " production memory ".
