I created a custom solver which assign planning variables to planning entities. I have a simple rule checking if there are no assign variable that adds negative soft constraint. But when I assigned my planning variable it increases the negative score instead of reducing it. I have for example 12 entities and my starting score was 0/-12.But when I initialized it with 4 variables it increases to 0/-16. rule "null variable" when $myEntity : Entity( variable == null ) then scoreHolder.addSoftConstraintMatch(kcontext, 0, -1); end -- View this message in context: http://drools.46999.n3.nabble.com/SolutionInitializer-for-Nullable-Planni...
