Now the next move will be on node B and its turn for MIN now.

Nodes are pruned when {useAb? 'β ≤ α': 'value is in cutoff range'}. This application allows the creation and manipulation of trees and the execution of the algorithms Minimax e Alpha-Beta Prunning.

game tree that the computer has to look at in order to find the best possible move. We start with a basic algorithm called minimax that searches through the entire tree, then add the following components: Alpha-Beta Pruning Forced Moves Random Searches 1/-1 Termination These algorithms serve as the building blocks of modern game-playing com-puters. Alpha-beta pruning Pruning does not affect final result Amount of pruning depends on move ordering Should start with the “best” moves (highest-value for MAX or Can also try to remember “killer moves” from other branches of the tree With perfect ordering, the time to find the best move is reduced to O(bm/2)from O(bm.

Alpha Beta Pruning is all about reducing the size (pruning) of our search tree. While a brute-force approach is an easier approach to use, it doesn’t necessarily mean it is the most optimal approach. Many times, one doesn’t need to visit all possible branches to come up with the best possible solution in hand. Jul 18, Alpha-beta (AB) pruning is an improvised version of the Minimax algorithm. The search optimization technique employed by this pruning algorithm cuts down the spread of search and reduces the computation time considerably.

Minimax algorithm exhaustively reviews all the nodes in the search tree for maximizer turn and minimizer turn and decides the best possible course whereas AB-Pruning skips some of the branches in the search tree Estimated Reading Time: 6 mins.

Alpha-beta pruning is a modified version of the minimax algorithm. It is an optimization technique for the minimax algorithm. As we have seen in the minimax search algorithm that the number of game states it has to examine are exponential in depth of the tree.
