Abstract

The term "instance based methods" (IMs) refers to a certain family of methods for first-order logic theorem proving. IMs share the principle of carrying out proof search by maintaining a set of instances of input clauses and analyzing it for satisfiability until completion. IMs are conceptually essentially different to well established methods like resolution or free-variable analytic tableaux. (See [Pla94] for a comparison of various calculi and strategies, including an instance based method.) Also, IMs exhibit a search space and termination behaviour (in the satisfiable case) different from those methods, which makes them attractive from a practical point of view as a complementary method.
