Layered Clause Selection for Theory Reasoning (Short Paper)

Popis výsledku v původním jazyce

Explicit theory axioms are added by a saturation-based theorem prover as one of the techniques for supporting theory reasoning. While simple and effective, adding theory axioms can also pollute the search space with many irrelevant consequences. As a result, the prover often gets lost in parts of the search space where the chance to find a proof is low. In this paper, we describe a new strategy for controlling the amount of reasoning with explicit theory axioms. The strategy refines a recently proposed two-layer-queue clause selection and combines it with a heuristic measure of the amount of theory reasoning in the derivation of a clause. We implemented the new strategy in the automatic theorem prover VAMPIRE and present an evaluation showing that our work dramatically improves the state-of-the-art clause-selection strategy in the presence of theory axioms.
