All Known Implementing Classes:
  AbstractDeciderScoreComparatorFactory, NaturalDeciderScoreComparatorFactory, ShiftingHardPenaltyDeciderScoreComparatorFactory

    public interface DeciderScoreComparatorFactory

extends LocalSearchSolverPhaseLifecycleListener

A DeciderScoreComparatorFactory creates a new DeciderScoreComparator each step, which compares 2 scores to decide the next step. That Score Comparator can consider shifting penalty, aging penalty, ... in which case it differs from the natural ordering of scores.
