  • 基于Alpha-Beta剪枝的欢乐斗地主残局辅助

    2019年4月17日更新：

    将搜索主函数优化为局部记忆化搜索，再次提高若干倍搜索速度

    更新了main和player，helper无更新

    Player-v3.0

     3.0版本在双方牌数不大于15张时，基本可以在1s内出解

    （OFast编译，CPU：I5-4210M，辣鸡CPU）

    2019年4月16日更新：

    优化了分支判断速度，快了若干倍

    更新了main和player，helper无更新

    Player-v2.0

    众所周知欢乐斗地主这个游戏有一个叫做残局的模式

    模式的特征：你和机器人都互相知道对方的牌，且对面的机器人绝顶聪明。

    正常的斗地主规则，问你要如何出牌，才能保证你一定能赢。

    我们考虑直接爆搜，发现需要搜一年。

    于是我们加一个Alpha-Beta剪枝来加速整个爆搜过程即可。

    貌似绝大部分情况下都是秒出结果的

    目前最长时间只搜了15s（这是v2.0的时间，旧版貌似接近一分钟了）

    正确率100%，快速通关利器233333

    输入牌型要求：2~9直接输入，JQKA直接输入，10用T表示，大王小王分别用Ww表示。

    输入顺子/连对要从小到大输入（按照斗地主规则的从小到大），输入三带一/对，四带二/对，需要先输入三张/四张，再输入剩下的东西

    代码貌似只要10k多一点

    注意细节

    两个关联文件的代码：
