Hard satisfiable formulas for DPLL-type algorithms

Computational Complexity 2007-05-23 v1

Abstract

We address lower bounds on the time complexity of algorithms solving the propositional satisfiability problem. Namely, we consider two DPLL-type algorithms, enhanced with the unit clause and pure literal heuristics. Exponential lower bounds for solving satisfiability on provably satisfiable formulas are proven.
