All Implemented Interfaces:

Direct Known Subclasses:
AssignmentCount, DeltaTimePreference, HardConflicts, WeightedHardConflicts

public abstract class PlacementSelectionCriterion
extends TimetablingCriterion

Abstract class for all criteria that are to be used only in the placement selection (do not have any impact on the overall solution value). Such criterion is for instance the number of hard conflict (values that have to be unassigned before a selected value can be assigned for the problem to remain consistent).
