The document summarizes a lecture on Alpha-Beta Pruning, an algorithm used in game trees to prune branches that cannot potentially contribute to the final outcome. In OpenMP, it is a requirement that a For loop may only have a single entry/exit point if the loop is to be made parallel. However, Alpha-Beta pruning breaks this rule, as it is possible to break out of the loop whenever pruning needs to be accomplished (in the pseudo code above, this will happen when β is less than or equal to α). Megha Sharma. 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).

By disregarding branches that will not affect the final decision, you can significantly reduce the search space and improve the performance of your algorithm. Forest. As the optimal values are known (they are 1 or -1), evaluation can be stopped as soon as a move with the desired value is found. A game can be thought of as a tree of possible future game states. By comparing alpha and beta at each node, it can avoid exploring subtrees where Alpha Beta Pruning Makes MiniMax more efficient If we search down the whole tree, the number of states is exponential to the depth of the tree Alpha Beta Pruning cuts away leaves when traversing tree Stops evaluating a state when at least one possibility has been found to prove worse then a previous found move Alpha-beta pruning is a powerful optimization technique for adversarial search algorithms, particularly in games and decision-making scenarios.
