蒟蒻的五子棋ai
逃离地球
2019-01-29 16:20:01
这是本蒟蒻的第一篇博客qwq（上一篇不算）
这次来讲一讲我才很久以前编的一个project——五子棋AI（刚从我的U盘里翻出来）
实际上我还是可以下赢这个AI的，因为这个AI不会下三三、三四这样的棋（不懂的可以去网上搜一搜，很好理解），也有一些奇奇怪怪的bug。
主要思路就是用**dfs**给每个没有下棋的点进行评分，从进攻、防守两个方面进行评分，看四周的棋子的数量，周围对方或自己的棋子连得越长，评分就越高，再把棋下在评分最高的位置。
那就直接上代码吧

有点长，大家不愿意看的就不用看了，可以下下来运行试一下(~~可以在机房里玩五子棋并在被发现时向教练解释说自己在调试程序~~)，遇到一些bug也可以私信我
现在已知的bug有：
1. 在棋下在五个子的中间连成五个子后胜负判断出错
2. ai会在靠近边界的地方试图连成五个棋，实际上连不成。
这两个bug我 ~~懒得改了~~ 有时间再改
代码风格可能比较奇怪，毕竟是我去年写的，那时还是一个蒟蒻 ~~现在也是~~，所以用了goto语句，注释也比较少，大家有看不懂的地方可以私信我，~~我可能也看不懂~~，那就这样吧，感谢各位巨佬阅读我的文章，祝你们akioi ~~好吧你们早就ak了~~
