摘要
本文对Ｐｅａｒｌ提出的Ａ＊算法所使用的可采纳性启发式函数ｈ的准确性和期望代价之间的精确关系的两个定理做了介绍，并提出和证明了为确保这两个定理正确性的附加条件．
wo theorems of the relationships between the validity of admissible heuristic function h and the expected cost in the A* algorithm made by Pearl is introduced first.An additional assumption required for the validity of these two theorems is given and also be proved in the paper.
