On the Complexity of Resolution Procedures for Theorem Proving
We study several procedures for theorem proving based on the resolution principle. We consider (1) Davis Putnam procedure; (2) regular resolution; (3) unrestricted resolution; (4) resolution with extension; and (5) several versions of bounded resolution. The powers of these procedures are compared. Exponential lower bounds are proved for the run-time of some of them.
