Minimax算法（极⼤极⼩算法）概念 是⼀种找出最⼩失败的可能的算法。意思就是两个⼈下棋，A和B下棋，A想要⾃⼰的利益最⼤化（失败的可能性最⼩），B想要A的利益最⼩化（B想要A输）。这个算法以及接下来的Alpha-Beta剪枝都是⼀种对抗性搜索算法（两个⼈互相对抗着下棋，俩⼈都想赢），是...
In this article, we will go through the basics of the Minimax algorithm along with the functioning of the algorithm. We will also take a look at the optimization of the minimax algorithm, alpha-beta pruning. What is the Minimax algorithm? Minimax is a recursive algorithm which is used to c...
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...
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....
Alpha-Beta Pruning Alpha–beta (𝛼−𝛽) algorithm was discovered independently by a few researchers in the mid 1900s. Alpha–beta is actually an improved minimax using a heuristic. It stops evaluating a move when it makes sure that it's worse than the previously examined move. Such move...
