In [Sch99], Schöning proposed a simple yet efficient randomized algorithm for solving thek-SAT problem. In the case of 3-SAT, the algorithm has an expected running time of poly(n)·E(4/3)n=O(1.3334n) when given a formulaFonnvariables. This was the up to now best running time known for an algorithm solving 3-SAT. Here, we describe an algorithm which improves upon this time bound by combining an improved version of the above randomized algorithm with other randomized algorithms. Our new expected time bound for 3-SAT isO(1.3302n).
