[rules-users] How to even out n buckets in Drools Planner?

[aitchnyu]

As follow up, I included my domain model and an incomplete rule

*Problem facts*:
Entity: 
    weight: int
Bucket:
    id: int

*Planning entity*:
EntityBucketAssignment
    entity: Entity
    bucket: Bucket (planning variable)

*The rule fragment is*:
when
    $b1:Bucket($id:id)
    $minSum:Number from accumulate(
	Entity(
	    bucket==$b1,
	    $weight:wieght
	    ),
	sum($wieght)
    )
    not($b2:Bucket(id!=$id)
	$minSum:Number from accumulate(
	    Entity(
		bucket==$b2,
		$weight:wieght
		),
	    sum($wieght)
	)
    )
then
    ...
	
Could you correct this?
