An approach to tableau inferencing with “hardwired” heuristics

In this paper we discuss a prototype of the tableau method which derives its rule base from Jeffrey's text [3]. The heuristics are a subset of those outlined for HARP by Oppacher and Suen [4]. The prototype was written in C and intended for use with the IBM family of microcomputers. We shall outline some of our implementation strategies and, insofar as is possible, contrast them with those of the earlier pioneering work of Oppacher and Suen.
