Type Parameters:

Sol -

All Known Subinterfaces:

ConstraintMatchAwareIncrementalScoreCalculator<Sol>

All Known Implementing Classes:

AbstractIncrementalScoreCalculator

public interface IncrementalScoreCalculator<Sol extends Solution>

Used for incremental java Score calculation. This is much faster than EasyScoreCalculator but requires much more code to implement too.

Any implementation is naturally stateful.
