说明：  人工智能算法实现：[1]A*算法c语言 ? 分步阅读 A*算法，A*（A-Star)算法是一种静态路网中求解最短路最有效的方法。估价值与实际值越接近，估价函数取得就越好。 A*[1]（A-Star)算法是一种静态路网中求解最短路最有效的方法。
(Algorithmic Implementation of Artificial Intelligence: [1]A* Algorithmic C Language Step-by-step reading A* algorithm, A* (A-Star) algorithm is the most effective way to solve the shortest path in static road network. The closer the estimated value is to the actual value, the better the evaluation function can be obtained. A*[1] (A-Star) algorithm is the most effective method to solve the shortest path in static road network.)
