Abstract: The path packing problem is an optimization problem with many important applications.However,it is NP-hard in computational complexity.Motivated by the idea of Hassin and Rubinstein,an approximation algorithm based on the max-TSP problem for the path packing problem in the complete graphs is presented,and its complexity and approximation ratio are analyzed;an instance based on LINGO software demonstrates the feasibility and efficiency of this algorithm.

Key words: path packing, Traveling Salesman Problem(TSP), Hamilton cycle, approximation algorithm, Linear Interactive and General Optimizer(LINGO)

摘要: 图的路包装问题是一类有着重要应用背景的最优化问题,然而它在计算复杂度上是NP-困难的。受Hassin和Rubinstein的思想启发,在max-TSP问题的基础上给出了完全图的路包装问题的近似算法,分析了算法的复杂度和近似比;基于LINGO软件的算例表明了算法的可行性和有效性。
