... The fastest algorithm for k-SAT. The best known upper bound for k-SAT is given by the algorithm proposed by Paturi, Pudlák, Saks, and Zane [17, 18]; this algorithm is called PPSZ. This algorithm consists of exponentially many runs of a polynomial-time procedure. This procedure is based on the follo ...
