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...

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....

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...
Alpha-beta剪枝 (Alpha-beta pruning) alpha-beta剪枝是由John McCarthy在1956年的一次会议中首先被提出(尽管该命名是后来的事了)。alpha-beta剪枝是一个用来裁剪掉博弈树某个完整分支的方法, 因此这些分支不需要被极小极大进行评估。实质上,算法在极小极大的递归中维护两个额外的值:alpha和beta。alpha是Max的最小...
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 ...
