针对大规模问题提出，利用人工智能，通过人机交换，逐步选择较优路径，再将选择的多个较优路径进行比较，寻求最优路径．通过许多算例以及和同样算例（CHN144）以往结果的比较，本法不仅省时、省力，且获得了更优的结果，说明本法的可行性和有效性.

In this paper, a method of artificitil intelegence-human-computor exchange is presented. The optimum path shall be selected step by step. Through comparision of many pathes selected, the approximate optimum path can be found. We give some examples and a comparision among the results sowed by this method and other methods for the CHN144t raveling salesman problem is also given. These works show that using this methocl, not only the labour and time are saved but also the more optimum results can be obtained. ...
