With the field of artificial intelligence in the classic A* algorithm to solve a common artificial intelligence eight digital problem. This paper introduces the eight digital issues, and then the A* algorithm is explained. For eight digital path is not given and proved the presence of the conditions and made a determination in advance. Valuation function defines a flexible, cost function analysis of the impact of the program efficiency, and Closed table several optimized to improve search efficiency, and achieved good results.
