Lecture 21: Paramodulation
In backward reasoning for intuitionistic logic equality can be handled
by simultaneous rigid E-unification which, unfortunately, is undecidable.
Much less is known about forward calculi such as the inverse method. We
therefore review some basic notions about equality reasoning in classical
resolution, starting with paramodulation, the first approach
toward eliminating equality axioms from (classical) resolution.
