AlphaBeta Pruning算法 classAlphaBetaPruning:"""参数:alpha为max层下界,beta为min层上界初始化:alpha、beta为-inf、inf,根结点为max层,整体max、min层交替遍历顺序:二叉树中序遍历(左中右)参数更新:向上:max层更新alpha,min层更新beta;向下:passPruning:(alpha >= beta)al

alpha和beta只向下传递(通过一层一层的递归调用,一开始那些最左边的、一层一层往下传的alpha和beta都是负无穷和正无穷。) 下图,往父节点返回值。更新alpha。 下图,我们快进了一些内容,直接跳到剪枝的部分。 当alpha<=beta时剪枝 代码实现 int alpha_beta_pruning(Node* position, int alpha, int beta, bool wh...
这样可以暴力搜索最佳路径,使得root最大,即我最大化自己的得分。 Alpha-Beta pruning是一种剪枝搜索策略,把明显不满足的枝叶剪掉。 还是以上图为例子,比如我们得到了B=3,可推得A我们至少可以得到A=3这个结果了。 此时搜索C的时候,发现第一个C=2,由于对手要MIN,因此C最多为2,2<3 =>我们是不可能选择C的,因...
To utilize the alpha-beta pruning, we consider the small cells as leaves on a tree with corresponding load values. To estimate these loads, we also utilize the G/G/1 queuing system. After finding the small cells which are probable for MLB&MRO conflict, we utilize the two-dimensional ...

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. ...
