Re: [rules-users] Fw: proble with localSearch

Ok, I found the problem. I did not copy the third planning variable value when cloning my planning entity. Problem fixed.

The two other planning variables are filled for each planning entity. I have put a printline in the setter of the troublesome planning variable:     @PlanningVariable(strengthComparatorClass = TasktypeStrengthComparator.class, nullable = false)     @ValueRange(type = ValueRangeType.FROM_SOLUTION_PROPERTY, solutionProperty = "tasktypes")     public TaskType getType() {         return type;     }     public void setType(TaskType type) {         System.out.println("Type set to " + type);         this.type = type;     }   And I get the following outprint: Type set to TL Type set to null Type set to TL Type set to TL Type set to null Type set to TL Type set to null Type set to TL Type set to null Type set to TL Type set to null Type set to TL Type set to TL Type set to null Type set to TL ... Type set to null Type set to TL Type set to null Type set to TL Note that I also tried to set the annotation property nullable to false. This seems to have no effect.

Enable DEBUG logging, so you can see in the construction heuristic log if it does steps which change that variable from null to a non-null value. If you have 2 <constructionHeuristics> configurations before the <localSearch> configuration (which I don't see how you could with the 5.5 CH behavior): I just fixed a bug/feature for 6.0 earlier this week to support that. Should drools planner take care of this or should I impose an extra rule to exclude these selections? software, for free! search (really new to it). java.lang.IllegalStateException: Phase localSearch started with an uninitialized Solution. First initialize the Solution. For example, run a phase constructionHeuristic first. org.drools.planner.core.localsearch.DefaultLocalSearchSolverPhase.phaseStarted(DefaultLocalSearchSolverPhase.java:120) You have a construction heuristic configured, so all @PlanningVariable's should be different from null after that phase is ended. check should be ok and not throw that exception. to disk an verify that all planning variables are now not null. inspect phaseScope.getSolverScope().getScoreDirector().getWorkingSolution(). > > >>This is my config: >><?xml version="1.0" encoding="UTF-8"?> <environmentMode>DEBUG</environmentMode> >>    <!-- Domain model configuration --> <solutionClass>be.axi.planner.app.InspectionSchedule</solutionClass> <planningEntityClass>be.axi.planner.domain.Task</planningEntityClass> >>    <!-- Score configuration --> >>    <scoreDirectorFactory> <scoreDefinitionType>HARD_AND_SOFT</scoreDefinitionType> <scoreDrl>/inspectionRules.drl</scoreDrl> >>    </scoreDirectorFactory> >>    <constructionHeuristic> <constructionHeuristicType>BEST_FIT_DECREASING</constructionHeuristicType> constructionHeuristicPickEarlyType>FIRST_LAST_STEP_SCORE_EQUAL_OR_IMPROVING</constructionHeuristicPickEarlyType--> >>    </constructionHeuristic> >>    <localSearch> >>        <termination> <terminationCompositionStyle>OR</terminationCompositionStyle> <maximumSecondsSpend>3600</maximumSecondsSpend> <scoreAttained>0hard/0soft</scoreAttained> <planningVariableName>period</planningVariableName> <planningVariableName>spector</planningVariableName> <planningVariableName>type</planningVariableName> >>                </valueSelector> >>            </changeMoveSelector> >>            <swapMoveSelector> >>            </swapMoveSelector> >>        </unionMoveSelector> >>        <acceptor> <planningEntityTabuSize>7</planningEntityTabuSize> >>        </acceptor> >>        <forager> <minimalAcceptedSelection>1000</minimalAcceptedSelection> >>        </forager> >>    </localSearch> >></solver> >> Any thoughts on what I'm doing wrong? >>Thanks >>Michiel >>----------------- >>http://www.codessentials.com - Your essential software, for free! >>Follow us at http://twitter.com/#!/Codessentials >>_______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
