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,因为有更优的B。因此C无需继续搜索即可剪枝。
Alpha-beta pruning is a technique for pruning trees in artificial intelligence game-playing. This note draws an analogy between the technique, which is, in essence, an application of many-valued logic to the cut-off of the evaluation of conditionals in computer programs (for efficiency). 年份:...

Alpha-Beta Pruning
一图流解释 Alpha-Beta 剪枝(Alpha-Beta Pruning) Alpha-Beta剪枝用于裁剪搜索树中不需要搜索的树枝,以提高运算速度。它基本的原理是: 当一个 Min 节点的 β值≤任何一个父节点的α值时 ,剪掉该节点的所有子节点 当一个 Max 节点的 α值≥任何一个父节点的β值时 ,剪掉该节点的所有子节点...
