我有6个条件：

c1 = ...
c2 = ...

然后，如果其中 4 个被填满（产生 15 个组合），我将执行一些命令。如何做到这一点？

例如：

cb1 = c1 and c2 and c3 and c4
cb2 = c1 and c2 and c3 and c5
cb3 = c1 and c2 and c3 and c6
cb4 = c1 and c2 and c4 and c5
cb5 = c1 and c2 and c4 and c6
cb6 = c1 and c2 and c5 and c6
cb7 = c1 and c3 and c4 and c5
cb8 = c1 and c3 and c4 and c6
cb9 = c1 and c3 and c5 and c6
cb10 = c1 and c4 and c5 and c6
cb11 = c2 and c3 and c4 and c5
cb12 = c2 and c3 and c4 and c6
cb13 = c2 and c3 and c5 and c6
cb14 = c2 and c4 and c5 and c6
cb15 = c3 and c4 and c5 and c6

// Set up alert
alertcondition(condition=cb1 or cb2 or cb3 or cb4 or cb5 or cb6 or cb7 or cb8 or cb9 or cb10 or cb11 or cb12 or cb13 or cb14 or cb15,
     message="cb")

【解决方案1】：

您可以阅读this 了解一些信息。

if (condition1 == true) and (condition2 == true) and (condition3 == true) and (condition4 == true)
    // Do something
else if (condition2 == true) and (condition3 == true) and (condition4 == true) and (condition5 == true)
    // Do something else

请注意缩进。

对于 6 例中的 4 例，剩下 16 种不同的组合。在 6 个案例中有 5 个不同的组合几乎爆炸了......是否有一个优雅的（即更紧凑的）配方代替？例如选择某个子集需要满足某些条件的数组或集合？

【解决方案2】：

我们可以做积分系统吗？例子

condition1 is ok X=1
condition2 is ok X=x+1
condition3 is ok X=x+3
condition4 is ok X=x+4

if x>0
do this
else if x>1
do this
else if x>2
do this    
...
