摘要
基于极大化P_(3)-填充,研究并设计Max_TSP算法。研究发现,Hassin等之前发表在《Information Processing Letters》上的一文中,任意边染色方案可能出现顶点相交的3-边路径的情况,即辅助图的边染色方案无效。在此基础上,通过反例说明其错误所在,并给出有效的边染色方案,更正了该算法的近似分析。
This paper revisits a Max_TSP algorithm designed through a maximum P_(3)-packing,which is previously published in Information Processing Letters.We first point out an error in the analysis of the algorithm that the coloring of edges on the auxiliary graph is invalid.Then we construct a new auxiliary graph and provide a valid coloring scheme for it.This corrects the approximation analysis of the known algorithm.
