public final class BendableScore extends AbstractScore<BendableScore> implements FeasibilityScore<BendableScore>
Score
is based on n levels of int constraints.
The number of levels is bendable at configuration time.
This class is immutable.
The getHardLevelsSize()
and getSoftLevelsSize()
must be the same as in the
