Hi Samuel, None of my implementations have a null instance asserted into the working memory. Which code is doing insertLogical(null)? IMHO, It shouldn't do that.
In your code I noticed last time that you used smart functions. The problem is, those smart functions don't use DRL, so don't do forward chaining, re-iterated over a lot of stuff while calculating the result, so they break delta score calculation. Those smart functions also did a lot of things that looked like black magic to me, which could be causing your wierd behaviour. Maybe you can rewrite those functions as DRL patterns? http://fisheye.jboss.org/browse/~raw,r=31102/JBossRules/trunk/drools-docs/drools-docs-planner/src/main/docbook/images/Chapter-Score_calculation/deltaBasedScoreCalculationNQueens04.svg With kind regards, Geoffrey De Smet Samuel Deballon schreef: > Hi all, Hi Geoffrey, > > I have implemented a first version of the solution with two types of move : > status move and another tour move. > > When i try to retrieved the scoreDetailList, the iterateObject is not clean. > It contains many null values.
