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.
