public final class HardSoftLongScore extends AbstractScore<HardSoftLongScore> implements FeasibilityScore<HardSoftLongScore>
Score is based on 2 levels of long constraints: hard and soft.
Hard constraints have priority over soft constraints.
This class is immutable.

In a normal score comparison, the soft score is irrelevant if the 2 scores don't have the same hard score.

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.

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<HardSoftLongScore>divisor - value by which this Score is to be dividedpublic HardSoftLongScore 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.

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}
