New Approximation Algorithms for Max 2sat and Max Dicut
We propose a 0.935-approximation algorithm for MAX 2SAT and a 0.863-approximation algorithm for MAX DICUT. The approximation ratios improve upon the recent results of Zwick, which are equal to 0.93109 and 0.8596434254 respectively. Also proposed are derandomized versions of the same approximation ratios. We note that these approximation ratios are obtained by numerical computation rather than t...
متن کاملAn 0.5-Approximation Algorithm for MAX DICUT with Given Sizes of Parts
Given a directed graph G and an edge weight function w : E(G) → R+, the maximum directed cut problem (max dicut) is that of finding a directed cut δ(X) with maximum total weight. In this paper we consider a version of max dicut — max dicut with given sizes of parts or max dicut with gsp — whose instance is that of max dicut plus a positive integer p, and it is required to find a directed cut δ(...
متن کاملAproximating the Value of Two Prover Proof Systems, With Applications to MAX 2SAT and MAX DICUT
It is well known that two prover proof systems are a convenient tool for establishing hardness of approximation results. In this paper, we show that two prover proof systems are also convenient starting points for establishing easiness of approximation results. Our approach combines the Feige-Lovv asz (STOC92) semideenite programming relaxation of one-round two-prover proof systems, together wi...
