This involves two threshold parameter Alpha and beta for future expansion, so it is called alpha-beta pruning. It is also called as Alpha-Beta Algorithm . Alpha-beta pruning can be applied at any depth of a tree, and sometimes it not only prune the tree leaves but also entire sub-tree.
Jun 13, 2024 · Alpha-beta pruning is an optimization technique for the minimax algorithm. It reduces the number of nodes evaluated in the game tree by eliminating branches that cannot influence the final decision.
Alpha–beta pruning is a search algorithm that seeks to decrease the number of nodes that are evaluated by the minimax algorithm in its search tree. It is an adversarial search algorithm used commonly for machine playing of two-player combinatorial games ( Tic-tac-toe, Chess, Connect 4, etc.).
May 15, 2023 · Alpha Beta Pruning is an optimization technique of the Minimax algorithm. This algorithm solves the limitation of exponential time and space complexity in the case of the Minimax algorithm by pruning redundant branches of a game tree using its parameters Alpha( α \alpha α ) and Beta( β \beta β ).
Mar 31, 2017 · 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.
Apr 10, 2021 · Alpha-beta pruning can provide performance optimization up to the square root of the performance of the original minimax algorithm. It may also provide no performance improvement at all, depending on how unlucky you are.

Alpha-beta pruning is the standard searching procedure used for solving 2-person perfect-information zero sum games exactly. Definitions: A position p. The value of a position p, f (p), is a numerical value computed from evaluating p. Value is computed from the root player’s point of view.
Alpha-beta pruning is an improvement over the minimax algorithm. The problem with minimax is that the number of game states it has to examine is exponential in the number of moves. While it is impossible to eliminate the exponent completely, we are able to cut it in half.
Nov 21, 2021 · Implementing alpha-beta pruning. The first step to implementing alpha-beta pruning is modifying the minimax algorithm so that it also accepts values for alpha and beta , which can have default values of −∞ − ∞ and +∞ + ∞, respectively: def pruning(tree, maximising_player, alpha=float("-inf"), beta=float("+inf")): ...
