我正在解决与车辆路径问题类似的问题，我有一条规则可以避免多名员工同时使用同一车辆。另外，我使用多级可弯曲分数仅用于详细分数计算。 有了这条规则 我启用了FAST_ASSERT，并且我发生了以下异常：
java.lang.IllegalStateException: Impossible VariableListener corruption: the expectedWorkingScore
(-788init/[0/0/-10/-20/-3/0/-12/-788/0/0]hard/[0/0/-25/-75/0]soft) is not the workingScore
(-788init/[0/0/-10/-60/-3/0/-12/-788/0/0]hard/[0/0/-25/-75/0]soft) after all VariableListeners were triggered without changes to the genuine variables.
But all the shadow variable values are still the same, so this is impossible.

在AbstractScoreDirector中，我查看了移动类型及它的ChainedChangeMove，它的toString看起来像：
T:1568135-2-10- {T:1656844-2-10- -> T:1656844-2-10-}
这令我感到惊讶，因为它试图将相同的链分配给实体（1656844是链中的第一个实体）。
A.需要帮助理解上述异常，以便我可以修复它。
B.我们如何确保移动创建者不会创建无用的移动，即将相同的事实分配给之前的实体，就像上面一样？
更新了FULL_ASSERT例外：
java.lang.IllegalStateException: Score corruption: the workingScore
([0/0/0/-1440/-602/0/-633/0/0/0]hard/[-120/0/-813/-2946/0]soft) is not the uncorruptedScore
