public final class HardMediumSoftScore extends AbstractScore<HardMediumSoftScore> implements FeasibilityScore<HardMediumSoftScore>
Score is based on 3 levels of int constraints: hard, medium and soft.
Hard constraints have priority over medium constraints.
Medium constraints have priority over soft constraints.
Hard constraints determine feasibility.
This class is immutable.

public int getMediumScore()
In a normal score comparison, the medium score is irrelevant if the 2 scores don't have the same hard score.
public int getSoftScore()
In a normal score comparison, the soft score is irrelevant if the 2 scores don't have the same hard and medium score.
public HardMediumSoftScore withInitScore(int newInitScore)
Score0hard/-8soft with -7 returns -7init/0hard/-8soft.withInitScore in interface Score<HardMediumSoftScore>newInitScore - always negative (except in statistical calculations), 0 if all planning variables are initializedScore.getInitScore() is set to newInitScorepublic boolean isFeasible()

Scoreadd in interface Score<HardMediumSoftScore>addend - value to be added to this Scorepublic HardMediumSoftScore subtract(HardMediumSoftScore subtrahend)
Scoresubtract in interface Score<HardMediumSoftScore>subtrahend - value to be subtracted from this Scorepublic HardMediumSoftScore multiply(double multiplicand)
ScoreMath.floor(double)).
If the implementation has a scale/precision, then the unspecified scale/precision of the double multiplicand should have no impact on the returned scale/precision.
multiply in interface Score<HardMediumSoftScore>multiplicand - value to be multiplied by this Score.public HardMediumSoftScore divide(double divisor)
ScoreMath.floor(double)).
If the implementation has a scale/precision, then the unspecified scale/precision of the double divisor should have no impact on the returned scale/precision.
divide in interface Score<HardMediumSoftScore>divisor - value by which this Score is to be dividedpublic HardMediumSoftScore power(double exponent)
ScoreMath.floor(double)).
If the implementation has a scale/precision, then the unspecified scale/precision of the double exponent should have no impact on the returned scale/precision.
power in interface Score<HardMediumSoftScore>exponent - value by which this Score is to be poweredpublic HardMediumSoftScore negate()
Scorenegate in interface Score<HardMediumSoftScore>public Number[] toLevelNumbers()
Score
When rounding is needed, each rounding should be floored (as defined by Math.floor(double)).
The length of the returned array must be stable for a specific Score implementation.
For example: -0hard/-7soft returns new int{-0, -7}
The level numbers do not contain the Score.getInitScore().
For example: -3init/-0hard/-7soft also returns new int{-0, -7}
toLevelNumbers in interface Score<HardMediumSoftScore>ScoreDefinition.fromLevelNumbers(int, Number[])public int compareTo(HardMediumSoftScore other)
compareTo in interface Comparable<HardMediumSoftScore>public String toShortString()
ScoreObject.toString(), but trims score levels which have a zero weight.
For example 0hard/-258soft returns -258soft.
Do not use this format to persist information as text, use Object.toString() instead,
so it can be parsed reliably.
