Hi thanks lot, for the last one week I am breaking my head to understand the
drools planner.
I have two questions...
1) When to use Unweighted constrains?
2) Is any way I can combine the following two rules in to one rule, I mean
writing length and width in one rule condition instead of two. I tried but I
dont know how to use the accumulate for 2d constraint. Is any alternate way
to write this condition.
I really appreciate your patients and time, thanks lot again

rule "requiredLengthTotal"
when
$room : Room($length : length)
$requiredSpaceTotal : Number(intValue > $length) from accumulate(
Table(
room == $room,
$tablelength : length),
sum($tablelength)
)
then
insertLogical(new IntConstraintOccurrence("requiredLengthTotal",
ConstraintType.NEGATIVE_HARD,
$requiredSpaceTotal.intValue() - $length,
$room));
end
rule "requiredWidthTotal"
when
$room : Room($width : width)
$requiredSpaceTotal : Number(intValue > $width) from accumulate(
Table(
room == $room,
$tablewidth : width),
sum($tablewidth)
)
then
insertLogical(new IntConstraintOccurrence("requiredWidthTotal",
ConstraintType.NEGATIVE_HARD,
$requiredSpaceTotal.intValue() - $width,
$room));
end

with kind regards,
