Width and size of regular resolution proofs

Computational Complexity 2015-07-01 v3 Logic

Abstract

This paper discusses the topic of the minimum width of a regular resolution refutation of a set of clauses. The main result shows that there are examples having small regular resolution refutations, for which any regular refutation must contain a large clause. This forms a contrast with corresponding results for general resolution refutations.
