如何使用Solver Foundation来简化决策矩阵

Question

已经挣扎了一段时间，希望在这里寻求一些建议。首先，决策矩阵是这样的:

条件1 ->条件2 ->决策

 Yes           Yes          Go ahead
 Yes            No          Go ahead
  No           Yes          Go ahead
  No            No          Give up

假设:1. 我们只考虑上面的序列("->")。2. 条件1 &只有"是"one_answers"不是"。

简化的标准是，如果在最后一个条件的所有可能选项下做出相同的决策，那么在相同的last-1条件下可以省略最后一个条件。例如

For decision "Go ahead" *，

条件1 ->条件2 ->决策

 Yes        Yes =>  X       Go ahead
 Yes        Yes =>  X       Go ahead
  No           Yes          Go ahead

我最初的想法是在这部分(*)中应用求解器基础，而其他部分则由传统编程处理，如for循环和递归。在这种情况下，最终答案应该是

条件1 ->条件2 ->决策

 Yes             X          Go ahead
  No           Yes          Go ahead
  No            No          Give up

我陷入的是以下逻辑的实现:

的决定,目标:从集合*中选择最小的索引i(即选择一个表示要简化的键的大小写)。

约束:选择条件1等于条件1的情况，然后检查在所有选择的情况下是否在条件2中出现所有可能的选项。

一旦我们得到决定，即0，我们知道条件1为"是"的情况下可以省略条件2。

看谁能帮上忙。谢谢。

Answer 1

是否可以像这样使用if命令

if (Condition_One || Condition_Two)
{
 //Go ahead command
}
else
{
//Give up code
}

如果你能提供一个示例代码，这将有助于别人回答…

谢谢
