比较器电路值问题的复杂性分类与理论

Complexity Classes and Theories for the Comparator Circuit Value Problem

Stephen A. Cook, Dai Tri Man Le, Yuli Ye

摘要:

Subramanian将复杂性类CC定义为可归约为比较器电路值问题的对数空间问题集。他证明了其他几个问题是完整的CC,包括稳定的婚姻问题,并找到字典的第一个最大匹配的二分图。我们建议CC的替代定义的基础上不同的可约性,并介绍了两个排序的理论VCC* 基于其中之一。我们锐化和简化Subramanian的完整性证明,上述两个问题,并在VCC* 形式化。

英文摘要:

Subramanian defined the complexity class CC as the set of problems log-space reducible to the comparator circuit value problem. He proved that several other problems are complete for CC, including the stable marriage problem, and finding the lexicographical first maximal matching in a bipartite graph. We suggest alternative definitions of CC based on different reducibilities and introduce a two-sorted theory VCC* based on one of them. We sharpen and simplify Subramanian's completeness proofs for the above two problems and formalize them in VCC*.
