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...
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...

How does alpha-beta pruning work? Initialize alpha = -infinity and beta = infinity as the worst possible cases. The condition to prune a node is when alpha becomes greater than or equal to beta. Start with assigning the initial values of alpha and beta to root and since alpha is less th...
Minimax极⼤极⼩算法、Alpha-BetaPruning剪枝算法 这篇博客分为两部分。⾸先我会先讲极⼤极⼩算法，然后在此基础上进⾏改进给出进阶版的Alpha-Beta剪枝算法以及代码实现。⽂中配备b站讲解的视频，感兴趣的可以看⼀下视频讲解，然后复习的时候拿着⽂章当作参考。Minimax算法（极⼤极⼩算法）概念 是...
It's a nice way to show the # distinction between the basic Minimax and Minimax with # alpha-beta pruning :) import time class Game: def __init__(self): self.initialize_game() def initialize_game(self): self.current_state = [['.','.','.'], ['.','.','.'], ['.','.'...
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....
Alpha-beta剪枝(Alpha-beta pruning) 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 ...
