Finally, it may be worth noting that a similar optimization is widely used in game-playing programs, where it is called alpha-beta pruning.

最后，值得注意的是，类似的优化已经广泛应用于电子游戏的程序，在那里被称为alpha - be ta剪枝。

In addition, programmers have come up with all sorts of algorithms and tricks such as Alpha-Beta pruning, Negascout, and MTD(f) in order to lessen the number of nodes the computer must examine.

此外，程序员们也提出了很多算法和技巧来减少节点数目，比如阿尔法 贝塔剪枝算法（Alpha-Beta pruning），Negascout搜索算法以及MTD（全称是：Memory enhanced Test Driver，即记忆增强测试驱动，译者注）方法。
