A*搜寻算法 A* search algorithm

(重定向自A Star)

A*搜索算法,俗称A星算法。这是一种在图形平面上,有多个节点的路径,求出最低通过成本的算法。常用于游戏中的NPC的移动计算,或在线游戏的BOT的移动计算上。

该算法综合了BFS(Breadth First Search)和Dijkstra算法的优点:在进行启发式搜索提高算法效率的同时,可以保证找到一条最优路径(基于评估函数)。

在此算法中,如果以 g(n)表示从起点到任意顶点n的实际距离,h(n)表示任意顶点n到目标顶点的估算距离(根据所采用的评估函数的不同而变化),那幺 A*算法的估算函数为:

这个公式遵循以下特性:

A* search algorithm A*搜寻算法

(重定向自A Star)
A* was invented by researchers working on Shakey the Robot's path planning.
Illustration of A* search for finding path from a start node to a goal node in a robot motion planning problem. The empty circles represent the nodes in the open set, i.e., those that remain to be explored, and the filled ones are in the closed set. Color on each closed node indicates the distance from the start: the greener, the farther. One can first see the A* moving in a straight line in the direction of the goal, then when hitting the obstacle, it explores alternative routes through the nodes from the open set. See also: Dijkstra's algorithm

In computer science, A* (pronounced as "A star" ( listen)) is a computer algorithm that is widely used in pathfinding and graph traversal, the process of plotting an efficiently traversable path between multiple points, called nodes. Noted for its performance and accuracy, it enjoys widespread use. However, in practical travel-routing systems, it is generally outperformed by algorithms which can pre-process the graph to attain better performance, although other work has found A* to be superior to other approaches.
