图论中的团划分(CP)问题是NP完全问题,很难在多项式时间内求解,本文研究了CP问题的固定参数算法,提出了一种新的无K4图的约简规则,并结合深度界搜索树的方法,它提高了K4-K5中团划分的固定参数可处理(FPT)算法的运行时间。实验结果表明,在稀疏图的情况下,改进算法的效率比原算法提高了至少30%。
Clique Partition(CP) problem in graph theory is NP-complete,so it's difficult to solve it in polynomial time.This paper studies fixed parameter algorithm for CP and proposes a new reduction rule for K4-free graphs.Combing with the way of depth-bound search tree,it improves the running time of Fixed Parameter Tractable(FPT) algorithm for Clique partition in K4-free graph.Experimental results show that the efficiency of the improved algorithm is higher than the original at least thirty percent in the case of sparse graph.
