Examples of org.drools.planner.core.score.Score

org.drools.planner.core.score.Score
A Score is result of the score function (AKA fitness function) on a single possible solution.
Implementations must be immutable.
Implementations are allowed to optionally implement Pareto comparison and therefore slightly violate the transitive requirement of {@link Comparable#compareTo(Object)}. @see AbstractScore @see DefaultHardAndSoftScore
