Re: [rules-users] Planner 5.3.Final - "presumedScore is corrupted" when using "update" on the rules working memory

Thank you for the pointers.
My understanding is that since it is failing on the construction heuristic
(move/unmove not used at this point) then the issue would be in the score
rule?
yes, good assumption.
Here is my only score rule (ShiftAssignment is the only planning
entity with
shiftStartTime/shiftEndTime changing). Maybe something would jump at you:
rule "intervalRequirementCovered"
when
$intervalReq : IntervalRequirement($interval : interval, $position :
position, $staffingRequired : staffingRequired)
$matchingShiftAssignmentsCount : Number() from accumulate(
$matchingShiftAssignments : ShiftAssignment(shiftStartTime<=
$interval, shiftEndTime> $interval, position == $position),
count($matchingShiftAssignments)
)
then
insertLogical(new IntConstraintOccurrence("intervalRequirementCovered",
ConstraintType.NEGATIVE_HARD,
Math.min($matchingShiftAssignmentsCount.intValue() - $staffingRequired,
0), $intervalReq, $position));
Looks good, although I don't think the $position
cause is needed as
$intervalReq as a cause should be enough.
Also, I 'd change it like this:
... $matchingShiftAssignmentsCount : Number(intvalue< $staffingRequired) ...
and leave out the Math.min(..., 0) code.
Verify that IntervalRequirement doesn't change during planning.
Are you using drools-planner-core 5.3.0.Final with drools-core
5.3.0.Final and drools-compiler 5.3.0.Final?
end
Thanks,
Guy
