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.
This class is immutable.

public int getHardScore()
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.

.
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)
Score
Math.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)
Score
Math.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.

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}
