code: public void penalize(RuleContext kcontext, BigDecimal hardWeightMultiplier, BigDecimal mediumWeightMultiplier, BigDecimal softWeightMultiplier) {
          reward(kcontext, hardWeightMultiplier.negate(), mediumWeightMultiplier.negate(), softWeightMultiplier.negate());
      }
docs: Penalize a match by the {@link ConstraintWeight} negated and multiplied with the specific weightMultiplier per score level.
  Slower than {@link #penalize(RuleContext, BigDecimal)}.
  @param kcontext never null, the magic variable in DRL
  @param hardWeightMultiplier at least 0
  @param mediumWeightMultiplier at least 0
  @param softWeightMultiplier at least 0
