Alpha-beta 剪枝算法可以认为是 minimax 算法的一种改进,在实际的问题中,需要搜索的状态数量将会非常庞大,利用 alpha-beta 剪枝算法可以去除一些不必要的搜索。 关于alpha-beta 算法的具体解释可以看这篇文章Minimax with Alpha Beta Pruning。我们在前文中考虑的那张图就来自这篇文章,之后我们会用 alpha-beta 剪枝算...

Firstproposed by John McCarthy at a conference in 1956 (although only named as suchlater on), alpha-beta pruning is a method for cutting off whole branches of thegame tree so that they don’thave to be evaluated with minimax. In essence, the algorithm maintains twoextra values during the...
impossible to complete the full search and hence after reaching a depth d' (d << d) , we use a heuristic function to return a value based on the status of the game given at that node.Alpha-beta pruning is an algorithm to reduce the searching during minimax by pruning certain branches....
This can be improved using Alpha-Beta Pruning. In short Alpha-Beta pruning is a kind of search algorithm whose goal is to decrease the number of nodes that needs to be evaluated, hence making it work better and execute faster. Conclusion ...

The AI submitted is set with maximum 3 children for a node and depth 5 for the search tree. Alpha-beta pruning means that for every min node, if the parent node has already gotten a value larger than or equal to its current value, then we can prune the node from the graph. The ...
