Incremental theory reasoning methods for semantic tableaux
Theory reasoning is an important technique for increasing the
efficiency of automated deduction systems. In this paper we present
incremental theory reasoning, a method that improves the interaction
between the foreground reasoner and the background (theory) reasoner
and, thus, the efficiency of the combined system. The use of
incremental theory reasoning in free variable semantic tableaux
and the cost reduction that can be achieved are discussed; as an
example, completion-based equality reasoning is presented, including
experimental data obtained using an implementation
