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.
Jan 16, 2023 · It is called Alpha-Beta pruning because it passes 2 extra parameters in the minimax function, namely alpha and beta. Let’s define the parameters alpha and beta. Alpha is the best value that the maximizer currently can guarantee at that level or above.
May 15, 2023 · 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).
D3.js web app for visualizing and understanding the Alpha-Beta Pruning algorithm. Developed for UC Berkeley's CS61B.
Sep 2, 2024 · Alpha-beta pruning is nothing but the pruning of useless branches in decision trees. This alpha-beta pruning algorithm was discovered independently by researchers in the 1900s. Alpha-beta pruning is an optimisation technique for the minimax algorithm which is discussed in the next section.
Mar 31, 2017 · 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 than beta we don’t prune it. Carry these values of alpha ...
Nov 21, 2021 · Introduction. This article aims at providing the reader with an introduction to the minimax search algorithm, and to alpha-beta pruning – an optimisation over that same algorithm. I am writing this article as a complete beginner with regards to this topic, which hopefully will benefit you and me:

Aug 24, 2023 · Minimax with Alpha-Beta Pruning in Python. Mina Krivokuća. Introduction. Way back in the late 1920s John Von Neumann established the main problem in game theory that has remained relevant still today: Players s 1, s 2, ..., s n are playing a given game G. Which moves should player s m play to achieve the best possible outcome?
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.).
