Dijkstra’s algorithm builds a shortest path tree one edge at a time by first
adding the source node to the SPT and then by adding the edge that gives
the shortest path from the source to a node not already on the SPT. This
process results in an SPT containing the shortest path from every node in
the graph to the source node. (查看原文)
Dijkstra’s algorithm searches by minimizing the cost of the path so far. It
can be improved significantly by taking into account, when putting nodes
on the frontier, anestimateof the cost to the target from each node under
consideration. This estimate is usually referred to as aheuristic, and the
name given to the algorithm that uses this method of heuristically directed
search is A* (pronounced ay-star).
A* proceeds in an almost identical fashion to Dijkstra’s search algo-rithm. The only difference is in the calculation of the costs of the nodes on
the search frontier. The adjusted cost,F, to the node when positioned on the
priority queue (the search frontier), is calculated as:
F = G+H (5.3)
where G is the cumulative cost to reach a node andHis the heuristic e... (查看原文)

这本书是以实例为主的，整本书原理讲的比较少，代码和实例很多，看懂实例代码以后就可以用到自己的游戏中。

非常好的书,从移动到寻路,到目标抉择,美中不足是寻路的地块切分没有细讲,然后模糊逻辑那章稍微有点不好消化(翻译问题?)
