We give an exact, exponential-time but polynomial-space algorithm that is the fastest known for p=0, which includes the well-studied Max 2-Sat problem but also instances with arbitrary mixtures of AND and OR clauses; for an m-clause instance it runs in time O⋆(2m/6.321). The same ...
The maximum 2-satisfiability problem (MAX-2-SAT) is: given a Boolean formula in 2-CNF, find a truth assignment that satisfies the maximum possible number of its clauses. MAX-2-SAT is MAX-SNP-complete. Recently, this problem received much attention in the contexts of (polynomial-time) appr...
We then give a simple linear time algorithm based on a message passing method, and we prove that it solves the MAX-2SAT problem with high probability for random MAX-2SAT instances under this planted solution model for probability parameters within a certain range. 展开 关键词:...

()2. Max sat a basket the front of the bike. A. in; in B. on; in C. in; on 相关知识点: 试题来源: 解析 C句意为:“Max坐在自行车前面的篮 子里。 ”in a basket意为“在篮子里” ;自 行车的篮子一般是在自行车前面的上 方,故此处用on the front of the bike表 示“在自行车...
-|||-【解析】sat意思是“坐”,是st的过去式,前半句-|||-话Max sat in a basket意思是Max坐在一个篮子-|||-里。后面的介词短语为后置定语,修饰basket(篮-|||-子)。短语in the front ofi意为“在.….(内部-|||-的)前部”,篮子属于自行车的一部分,在自行车-|||-的前部。故本空应该填写介词...
Prior algorithms known for exactly solving Max 2-Sat improve upon the trivial upper bound only for very sparse instances. We present new algorithms for exactly solving (in fact, counting) weighted Max 2-Sat instances. One of them has a good performance if the underlying constraint graph has a...
