Derandomization of Schuler's Algorithm for SAT
Abstract. Recently Schuler [17] presented a randomized algorithm that solves SAT in expected time at most 2n(1−1/ log2(2m)) up to a polynomial factor, where n and m are, respecti...

List decoding algorithms for certain concatenated codes
We give efficient (polynomial-time) list-decoding algorithms for certain families of errorcorrecting codes obtained by "concatenation". Specifically, we give list-decodi...

Approximation Algorithms for Unique Games
We present a polynomial time algorithm based on semidefinite programming that, given a unique game of value 1 − O(1/ log n), satisfies a constant fraction of constraints, wher...
