    Topic. Faster k-SAT Algorithms Using Biased-PPSZ.
    Abstract. The PPSZ algorithm, due to Paturi, Pudlak, Saks and Zane, is currently the fastest known algorithm for the k-SAT problem, for every $k>3$. For 3-SAT, a tiny improvement over PPSZ was obtained by Hertli. We introduce a biased version of the PPSZ algorithm using which we obtain an improvement over PPSZ for every $k\geq 3$. For $k=3$ we also improve on Herli’s result and get a much more noticeable improvement over PPSZ, though still relatively small. In particular, for Unique 3-SAT, we improve the current bound from $1.308^n$ to $1.307^n$.

    Joint work with Thomas Dueholm Hansen, Haim Kaplan and Uri Zwick.
