Abstract

A simple unification algorithm for terms containing variables, constants and the set operators intersection and symmetric difference is presented. The solution is straightforward because the algebraic structure under consideration is a boolean ring. The main part of the algorithm is finding a particular solution which is then substituted into a general formula to yield a single most general unifier. The combination with other equational theories is briefly considered but even for simple cases the extension seems non-trivial.
