org.optaplanner.core.api.score.buildin.hardsoftbigdecimal.HardSoftBigDecimalScore
public final class HardSoftBigDecimalScore
This Score is based on 2 levels of BigDecimal constraints: hard and soft.
Hard constraints have priority over soft constraints.

FeasibilityScoreSolution is feasible if it has no broken hard constraints.
isFeasible in interface FeasibilityScore<HardSoftBigDecimalScore>public HardSoftBigDecimalScore add(HardSoftBigDecimalScore augment)
Score
add in interface Score<HardSoftBigDecimalScore>augment - value to be added to this Score
public HardSoftBigDecimalScore subtract(HardSoftBigDecimalScore subtrahend)
Score
subtract in interface Score<HardSoftBigDecimalScore>subtrahend - value to be subtracted from this Score
public HardSoftBigDecimalScore 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<HardSoftBigDecimalScore>multiplicand - value to be multiplied by this Score.
public HardSoftBigDecimalScore 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<HardSoftBigDecimalScore>divisor - value by which this Score is to be divided
public HardSoftBigDecimalScore 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<HardSoftBigDecimalScore>exponent - value by which this Score is to be powered
public HardSoftBigDecimalScore negate()
Score
negate in interface Score<HardSoftBigDecimalScore>public Number[] toLevelNumbers()
ScoreMath.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}
