我正在尝试使用MoveSelectionFilter从计划中排除一些计划权限实例。
但是,即使我拒绝所有移动,根据调试输出,实例仍然会在构造启发阶段初步计划。我正在使用WEAKEST_FIT启发式,两个自定义的MoveListFactories(目前根本不生成任何移动),也没有默认的MoveListFactory。
如何让OptaPlanner无法规划这些实体?我看过护士排班的例子,如果你推进约会但却无法重现这种行为,那么这就是我想要做的事情。
编辑:过滤器肯定正在应用。我检查了MoveLists的大小,它们都是空的。
我的过滤器如下所示:
public boolean accept(PatientAdmissionSchedule patientAdmissionSchedule, BedDesignation bedDesignation) {
return false;
}
如此应用:
if (filter.accept(patientAdmissionSchedule, bedDesignation)) {
for (Bed bed : bedList) {
moveList.add(new BedChangeMove(bedDesignation, bed));
}
}
和
for (ListIterator<BedDesignation> it = bedDesignationList.listIterator(); it.hasNext();) {
BedDesignation bedDesignation = it.next();
if (!filter.accept(patientAdmissionSchedule, bedDesignation)) {
it.remove();
}
}
在调试中,我有以下几行
2017-03-14 19:40:59,305 [SwingWorker-pool-4-thread-1] DEBUG CH step (31), time spent (173), score (0hard/0medium/0soft), selected move count (7), picked move (Patient6(Night(7),null) {null -> 15(0)}).
2017-03-14 19:40:59,306 [SwingWorker-pool-4-thread-1] INFO Construction Heuristic phase (0) ended: step total (32), time spent (174), best score (0hard/0medium/0soft).
2017-03-14 19:40:59,313 [SwingWorker-pool-4-thread-1] WARN No doable selected move at step index (0), time spent (181). Terminating phase early.
我认为进一步证明没有动作可供选择。
计划实体与患者入院计划示例中的计划实体基本相同:
@PlanningEntity(difficultyWeightFactoryClass = BedDesignationDifficultyWeightFactory.class)
@XStreamAlias("BedDesignation")
public class BedDesignation extends AbstractPersistable {
private Admission admission;
private Bed bed;
private Night night;
@PlanningVariable(nullable = true, valueRangeProviderRefs = {"bedRange"},
strengthComparatorClass = BedStrengthComparator.class)
public Bed getBed() {
return bed;
}
我也尝试过只使用一个返回空MoveList的MoveListFactory。但是仍有某些动作像这样
2017-03-14 19:40:59,305 [SwingWorker-pool-4-thread-1] DEBUG CH step (31), time spent (173), score (0hard/0medium/0soft), selected move count (7), picked move (Patient6(Night(7),null) {null -> 15(0)})
在构造启发阶段被选中。
