Alpha-Beta剪枝（Alpha-Beta Pruning）蒙塔卡洛树搜索（Monte-Caelo Tree Algorithm）最大最小算法是对抗搜索中最基本的搜索方法；Alpha-Beta剪枝算法是一种对最大最小搜索进行改进的算法，即在搜索过程中可以减去无需搜索的分支节点，且不影响搜索结果；蒙特卡洛树搜索通过采样而非穷举方法来实现搜索。

Alpha Beta Pruning Definition of Alpha-Beta Pruning 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....

This mechanism is based on the principle of pruning the unnecessary leaves on the tree. Thanks to this characteristic, we can overcome the ultra-density to reduce conflict detection time. To utilize the alpha-beta pruning, we consider the small cells as leaves on a tree with corresponding load...
