) Abstract: This paper provides an efficient implementation and optimization of a star algorithm, which finds a shortest path between two vertexes in a network graphic
In the same time, it provides several ways to improve the performance of the A* algorithm greatly by means of analyzing the common used data structure
And we can get a satisfactory test result by applying this algorithm to a commercial network graphic
