Java 扑克牌手评价的最简单算法
我正在考虑Java 扑克牌手评价的最简单算法,java,r,algorithm,data-structures,poker,Java,R,Algorithm,Data Structures,Poker,我正在考虑Java中的扑克手（5张牌）评估。现在我追求的是简单和清晰，而不是性能和效率。我可能可以写一个“幼稚”的算法，但它需要很多代码 我还看到了一些扑克评估库，它们使用哈希和按位操作，但它们看起来相当复杂 什么是“最干净、最简单”的扑克评估算法 如果您将一只手表示为一个数组，例如，卡对象，那么我将有一些方法来循环通过这个数组，并确定它是否有一个2-of-a-kind、flush等，如果有，它是什么类型；因此，如果一只手有三个5s，则可以使用3ofaKind（）方法返回5。然后我会建立一个可能
Java什么是“最干净、最简单”的扑克评估算法 如果您将一只手表示为一个数组，例如，
卡3ofaKind（）在任何情况下，查找解决方案都比柱状图-排序-跳舞-你的头上-比较-特殊情况-和-按方式-是-它-刷新解决方案快几个数量级，几乎没有一个值得再看一眼。如果你只想了解它是如何工作的，这里有一个简单的算法：
HandStrength(ourcards,boardcards)
{
ahead = tied = behind = 0
ourrank = Rank(ourcards,boardcards)
/* Consider all two-card combinations
of the remaining cards. */
for each case(oppcards)
{
opprank = Rank(oppcards,boardcards)
if(ourrank>opprank)
ahead += 1
else if(ourrank==opprank)
tied += 1
else /* < */
behind += 1
}
handstrength = (ahead+tied/2) / (ahead+tied+behind)
return(handstrength)
}
握力（我们的卡、板卡）
{
前=平=后=0
我们的等级=等级（我们的卡，董事卡）
*考虑所有两种卡组合
剩下的牌中的一张*/
每种情况（OPP卡）
{
opprank=等级（oppcards，boardcards）
如果（ourrank>opprank）
超前+=1
else if（ourrank==opprank）
平局+=1
else/*<*/
后面+=1
}
手的力量=（前+平/2）/（前+平+后）
返回（手的力量）
}
它来自Darse Billings的“计算机扑克中的算法和评估”。这里是Python（2.x）中一个非常简短但完整的基于直方图的5张扑克评分函数。如果转换为Java，它将变得相当长
