Abstract

We give a general goal directed method for solving the E- unification problem. Our inference system is a generalization of the inference rules for Syntactic Theories, except that our inference system is proved complete for any equational theory. We also show how to easily modify our inference system into a more restricted inference system for Syntactic Theories, and show that our completeness techniques prove completeness there also.
