The Do-loop Considered Harmful in Production System Programming

Biema, Michael van; Miranker, Daniel P.; Stolfo, Salvatore

In this paper we focus on some aspects of Expert System programming. In particular we consider some of the language constructs which from part of a new production system language known as Herbal that we are developing at Columbia University. These language constructs greatly increase the expressiveness of a typical production system language and can be efficiently executed on a para11el machine. We briefly describe the DADO machine under development at Columbia University and J basic algorithm for production system execution for that machine. We conclude with a discussion of some performance Statistics recently calculated from m _analysis of production systems simulations and describe the expected effects of our added language constructs on these statistics.
