Abstract
Let Φ be a uniformly distributed random kSAT formula with n variables and m clauses. We present a polynomial time algorithm that ﬁnds a satisfying assignment of Φ with high probability for constraint densities m/n < (1 − εk)2k ln(k)/k, where εk → 0. Previously no eﬃcient algorithm was known to ﬁnd satisfying assignments with a nonvanishing probability beyond m/n = 1.817 · 2k/k [A. Frieze and S. Suen, J. Algorithms, 20 (1996), pp. 312–355].
