# XSAT的新最差情况上限
New Worst-Case Upper Bound for #XSAT
摘要:
给出了一个O(1.1995n)的精确可满足性公式(#XSAT)模型计数算法。这比以前运行在O(1.2190n)的最佳算法更快。为了提高算法的效率,提出了一个新的原则,即共同文字原则,以简化公式。这使我们能够消除更常见的文字。此外,我们首次将归结原理引入到#XSAT问题的求解中,从而进一步提高了算法的效率。
英文摘要:
An algorithm running in O(1.1995n) is presented for counting models for exact satisfiability formulae(#XSAT). This is faster than the previously best algorithm which runs in O(1.2190n). In order to improve the efficiency of the algorithm, a new principle, i.e. the common literals principle, is addressed to simplify formulae. This allows us to eliminate more common literals. In addition, we firstly inject the resolution principles into solving #XSAT problem, and therefore this further improves the efficiency of the algorithm.
