What are some good methods to finding a heuristic for the A* algorithm?

You have a map of square tiles where you can move in any of the 8 directions. Given that you have function called cost(tile1, tile2) which tells you the cost of moving from one adjacent tile to anothe[详细]

Can I use Prim's algorithm instead of Dijkstra's to find shortest path?

I have been fighting all day in understanding Dijkstra\'s algorithm and implementing with no significant results. I have a matrix of cities and the开发者_如何学Goir distances. What I want to do is to[详细]

How to restrict shortest path - dijkstra algorithm with maximum cost?

I am wondering how I can assign a maximum cost value for the shortest path problem. In my problem, I have risks associated with nodes. So I would like to minimize risk, but while 开发者_StackOverflow社[详细]

how to find the best three routes using A* algorithm

In A* usually the result that you get is only one path. Is it possible though for a given origin and destination to have 3 recommended path according to A*? So the second returned is the second best p[详细]
