Optaplanner不使用其他BinAvailabilty来分配给事件

Question

        @PlanningEntity
        public class BinAvailablity {
            private int id;
            private Interval interval;
            private Bin bin;
            private int roomMax;
            @InverseRelationShadowVariable(sourceVariableName = "binAvailablity")
            private List<Event> events = new ArrayList<>();
            private List<Interval> nonAvailablity;
        }


    public class Event {

        private int id;
        @CustomShadowVariable(variableListenerClass = IntervalAssigningListener.class,
                sources = {@PlanningVariableReference(variableName = "binAvailablity")})
        private Interval interval;//assignning listener variable
        private boolean isPinned;
        private TotalTime totalTime;
        @PlanningVariable(valueRangeProviderRefs = "binAvailablities")
        private BinAvailablity binAvailablity;//plannig variable
        private List<Staff> staffList;
        private List<Equipment> equipmentList;
        private List<Interval> nonAvailability;}

我的配置是：-

@ PlanningSolution公共类EventBinAssignation {

private String id;

}

我已经创建了两个具有Event和BinAvailability的实体。我需要将事件分配给binAvailablity。但Optaplanner仅将事件分配给第一个binAvailability。 Optaplanner没有使用任何其他binAvailbility来分配得分被卡住的事件，但是它没有使用任何其他binavalilbity来分配具有某些特定条件的事件。因此请帮助。

Answer 1

如果OptaPlanner仅将事件分配给第一个binAvailability，则可能是因为您的硬约束不匹配（在scoreDrl中）。打开TRACE记录，并在每次CH移动期间寻找score编号。

或在DRL中将该约束的then中放入System.out.println。或迁移到ConstraintStreams并将调试器断点放在penalize() matchWeighter lamdba中。
