好的，所以我正在为我的高级项目制作德州扑克 AI。我已经创建了 gui 和投注/交易程序，但我已经到了需要确定谁赢了这手牌的部分，而且我不知道解决这个问题的最佳方法。我正在使用 python 顺便说一句。ATM 我有 2 个列表，一个用于 7 个玩家卡，一个用于 7 个计算机卡。目前所有的牌都以结构体的形式存储在列表中，如 {'Number': XX, 'Suit': x}，其中 number 为 2-14，suit 为 1-4。我打算解决这个问题的方法是为每种手型创建一个函数，从最高的开始。例如。self.CheckRoyal(playerCards)，并手动浏览列表并评估是否实现了皇家同花顺。必须有一种更好的数字方式来做到这一点。

ralu 帖子中使用的方法是迄今为止我见过的最好的选择。我在自己的项目中使用了这种方法，而且速度非常快。
悬崖：
进行一些预处理，以生成一个表，其中包含每个不同扑克手的一个值。确保表格按手力排序。
每个卡值都有一个对应的素值。该表由手中每个牌值的乘积来索引。因此，要找到手牌 AAAAK 的值，您需要计算素数乘法并将其用作表格的索引：
int prime = getPrime(hand); // Calculates A.getPrime()...*K.getPrime();
int value = table[prime];
（对不起java语法）。
这样，AAAAK 与 KAAAA 是同一手牌，您不需要 5 点表。
请注意，您需要通过最好的 5 张牌手的所有组合，以及您可以从中选择的 7 张牌，找到最大的值，这就是手牌的真正价值。
您使用不同的表进行冲洗。
该表变得非常强大，因为此实现有很多浪费的单元格。为了解决这个问题，您可以在预处理期间创建一个映射，它将大的素数映射到整数值，并将其用作您的源。
