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....
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...

If we apply alpha-beta pruning to a standard minimax algorithm, it returns the same move as the standard one, but it removes (prunes) all the nodes that are possibly not affecting the final decision. Let us understand the intuition behind this first and then we will formalize the algorithm...
