Re: [rules-users] Drools Planner: what if possible values of a PlanningVariable are dependent of another one?
ge0ffrey wrote
In OptaPlanner's architecture current philosophy, this is not
legal:
a value range should be stable for each variable (of each entity) during
solving.
This not guaranteed to work (and it is guaranteed not to work if you do
phase caching of moves:
it will invalidly exclude part of the search space).
So if I understand you correctly phase caching moves is the way to go?

If it does work for you, I am interested to know more about this - so
I
can consider to make this approach legal.
It is working for me, to give you a better impression of my approach i added
an image of my "planning classdiagram".

Observation contains 2 annotated planningVariables getScheduleBlock() and
getPeriod(). in the getPeriod() function it checks if the scheduleBlock is
not null, if so it uses scheduleBlock.getPlanningsPeriods() function to
return a list of periods.
If have any more questions feel free to ask, we are all working to make
OptaPlanner better. I can even send you a zip of my current code if you are
interested.
