Abstract

In this paper we describe and analyse an algorithm for solving the satisfiability problem. If E is a boolean formula in conjunctive normal form with n variables and r clauses, then we will show that this algorithm solves the satisfiability problem for formulas with at most k literals per clause in time O(|F|.@a"k^n), where @a"k is the greatest number satisfying @a"k = 2-1/@a"k^k^-^1 (in the case of 3-satisfiability @a"3 = 1,6181).
