A* (A

代码说明：

A*（A-Star)算法是一种静态路网中求解最短路最有效的方法。 公式表示为： f(n)=g(n)+h(n), 其中f(n) 是节点n从初始点到目标点的估价函数， g(n) 是在状态空间中从初始节点到n节点的实际代价， h(n)是从n到目标节点最佳路径的估计代价。 -A* (A-Star) algorithm is a static network shortest path in solving the most effective way. Formula is expressed as: f (n) = g (n)+ H (n), in which f (n) is a node n from the initial point to the target point of the valuation function, g (n) in state space from the initial node to node n of the actual cost, h (n) from n to the target node of the estimated cost of the best path.
