org.optaplanner.core.api.score.buildin.hardmediumsoftlong.HardMediumSoftLongScore
public final class HardMediumSoftLongScore
This Score
is based on 3 levels of long constraints: hard, medium and soft.
Hard constraints have priority over medium constraints.
Medium constraints have priority over soft constraints.
