很多同学和我表示对于对抗搜索中的Alpha Beta Pruning算法以及MinMax算法的区别总是搞混。
Alpha-beta pruning is an optimisation technique for the minimax algorithm which is discussed in the next section. The need for pruning came from the fact that in some cases decision trees become very complex. In that tree, some useless branches increase the complexity of the model. So, to av...
Alpha-beta剪枝本质是alpha剪枝和beta剪枝的结合,这两种剪枝的发生条件不同,因此在博弈中总是首先需要区分取极小值和取极大值方,这在一定程度上让算法的效率打了折扣。 未来发展方向 Alpha-beta剪枝是对极小化极大算法的一种改进,但是在实际应用过程中,alpha-beta剪枝首先要区分出博弈双方谁是取极大值者,谁是取...

Alpha-Beta剪枝算法(Alpha Beta Pruning) [说明] 本文基于<<CS 161 Recitation Notes - Minimax with Alpha Beta Pruning>>,文中的图片均来源于此笔记。 Alpha-Beta剪枝用于裁剪搜索树中没有意义的不需要搜索的树枝,以提高运算速度。 假设α为下界,β为上界,对于α ≤ N ≤β: ...
Minimax with Alpha-Beta Pruning Chess AI (α-β剪枝优化国际象棋人工智能)是一种用于国际象棋的人工智能算法。该算法使用Minimax算法来评估棋局,并结合α-β剪枝优化来提高搜索效率。 Minimax算法是一种基于回溯和深度优先搜索的决策树算法,用于评估棋局的最优解。它通过计算棋局中每个可能的移动后的最大价值和最小...

(like Minimax) search across all possible moves looking for the one that would guarantee a path to a board configuration with a high value. The search can be made efficient by not visiting configurations where we know that we won’t find a better value. That’s what Alpha–beta pruning ...
