Re: [rules-users] [Planner] CachedMoveFactory drive to Corrupted undo move
If someone got the same problem : I think i've found my problem. As i write it my undoMove was : (*new PlanMove(assigment, fromDay)*) Read : my fromDay was set in constructor and then it was set to the initial day. During solving assigments are plan on other days, but the undoMove always return to initial state. Example : Assigment1 is create at the DayFutur At init phase i create a cached move : Assigment1(DayFutur) to Day1 and i set the fromDay to DayFutur Then at runtime every times i do this move i create a undoMove : Assigment1 to DayFutur whatever the true old day was.

Re: [rules-users] [Planner] CachedMoveFactory drive to Corrupted undo move
I have test in TRACE mode, and I don't know what I can do with this error. In this test I have activated some Constraints. I've got a The presumedScore (0hard/-500soft) is corrupted because it is not the realScore (0hard/-450soft) I've got some questions : - When this error was launch ? - In Move classes could I use the same PlanningEntity instance in the move itself and his undomove ? or should i clone it ? - Are the causes of IntConstraintOccurrence important for delta score computing ? I will try to get the simpliest test case of this problem, to test it deeper.

Re: [rules-users] [Planner] CachedMoveFactory drive to Corrupted undo move
Thanks for your response. I'have juste test you proposition of method on assigment, and i've got the same error. I also test with a simplier rule set : Juste 1 rule : (and the two for scoreCalculator of course) rule notPlannified when $assigment: Assigment() then insertLogical(new IntConstraintOccurrence(notPlannified, ConstraintType.NEGATIVE_SOFT, 50, $assigment)); I desactivate the solverScope.calculateScoreFromWorkingMemory(); call in UI, juste in case. I check my cloneSolution : i juste clone the assigment object and copy the score. equals and hashcode are ok on assigment and move object. No overrided equals and hashcode on other facts, but since i don't recreate nor clone them, i think it's unnecessary. (In fact i don't really understand where hashcode and equals was really necessary since the working memory keep same instances). -- View this message in context: http://drools.46999.n3.nabble.com/Planner-CachedMoveFactory-drive-to-Corrupted-undo-move-tp3495070p3496696.html Sent from the Drools: User forum mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
[rules-users] [Planner] CachedMoveFactory drive to Corrupted undo move
Hello,
I'm almost new to Drools Planner, and i run into some problems.
One of them, I really want to understand is that my Planner works well until
i try to use a CachedMoveFactory instead of my MoveFactory, then i've got
Corrupted undo move at step 2.
Assigment are my PlanningEntity, Day are facts
My MoveFactory is like this :
for (final Assigment assigment: mySolution.getAllAssigments()) {
for (final Day day : mySolution.getAllDays()) {
moveList.add(new PlanMove(assigment, day));
}
}
And my doMove is like :
final FactHandle factHandle = workingMemory.getFactHandle(assigment);
assigment.setDay(toDay);
workingMemory.update(factHandle, assigment);
The UndoMove is really simple (new PlanMove(assigment, fromDay)) , so I
pretty sure this part is correct.
I have add a false day(future=true) which mean not plannified yet and all
assigment start at this day.
I have a rule like :
rule notPlannified
when
$assigment: Assigment( day.future )
then
insertLogical(new IntConstraintOccurrence(notPlannified,
ConstraintType.NEGATIVE_SOFT, 50, $assigment));
end
My logs show :
INFO Phase construction heuristic finished: step total (0), time spend
(255), best score (0hard/-18750soft).
DEBUG Step index (0), time spend (2175), score (0hard/-18700soft), new
best score (0hard/-18700soft), accepted move size (1000) for picked step
([A148@[UNAFFECT]] == [12/11]).
Someone can explain me what I miss ?
Thanks.
