问题描述
在计划过程中是否可以访问计划变量的分配?
Is there a way to access planning variable's assignment during planning?
在我的用例中,我只想在计划期间一次分配具有某些状态的计划变量.之后,我不想使用该计划变量.
In my use case, I want to assign a planning variable with certain status only one time only during planning. After that I don't want to use that planning variable.
我知道在optaplanner中,计划变量/问题事实无法更改,因此我无法更改其状态.
I know that in optaplanner, a planning variable/problem fact can not change, so i can not change its status.
是否有一种方法可以在计划过程中获取计划变量分配的列表,以便在Java代码或drools文件中,如果已使用一次,则可以避免重新分配?
Is there a way to get list of planning variable assignment during planning so that in java code or drools file, i can avoid re-assignment if it has been used once?
谢谢!
推荐答案
使用硬约束来强制实施.
是的,您也可以使用MoveFilters,但这不是一个好主意,因为有时您需要打破严格的约束条件才能逃脱局部最优.
Yes, you could use MoveFilters too, but that's not a good idea because sometimes you need to break hard constraints to escape local optima.
