Abstract: The relationship between the Hamilton circuit and the Traveling Salesman Problem is discussed.On the basis of this and the approximate algorithm of shortest path of the complete graph theory,a new approximate algorithm of TSP is proposed.Analyses and examples show that the approximate algorithm is effective.

Key words: graph theory, Hamilton circuit, Traveling Salesman Problem(TSP), approximate algorithm
