我们得到了大大改进的近似算法的MINK-SAT问题,叉= 2,3。更具体地说,我们得到了一个1.1037近似算法的MIN 2-SAT问题,改进了以前的1.5近似算法,和一个1.2136近似算法的MIN 3-SAT问题,改进了以前的1.75近似算法的问题。这些结果是通过调整技术,以前用于获得近似算法的MAXk-SAT问题。我们也得到了一些近似结果的硬度。
We obtain substantially improved approximation algorithms for the MINk-SAT problem, fork= 2,3. More specifically, we obtain a 1.1037-approximation algorithm for the MIN 2-SAT problem, improving a previous 1.5-approximation algorithm, and a 1.2136-approximation algorithm for the MIN 3-SAT problem, improving a previous 1.75-approximation algorithm for the problem. These results are obtained by adapting techniques that were previously used to obtain approximation algorithms for the MAXk-SAT problem. We also obtain some hardness of approximation results.
