HardSoftDoubleScoreDefinition()

Method Summary

HardSoftDoubleScore	buildOptimisticBound(InitializingScoreTrend initializingScoreTrend, HardSoftDoubleScore score) Builds a Score which is equal or better than any other Score with more variables initialized (while the already variables don't change).
HardSoftDoubleScore	buildPessimisticBound(InitializingScoreTrend initializingScoreTrend, HardSoftDoubleScore score) Builds a Score which is equal or worse than any other Score with more variables initialized (while the already variables don't change).
HardSoftDoubleScoreHolder	buildScoreHolder(boolean constraintMatchEnabled) Used by DroolsScoreDirector.
double	calculateTimeGradient(HardSoftDoubleScore startScore, HardSoftDoubleScore endScore, HardSoftDoubleScore score) See explanation in Termination.calculateSolverTimeGradient(DefaultSolverScope).
double	getHardScoreTimeGradientWeight()
int	getLevelCount()
Class<HardSoftDoubleScore>	getScoreClass() Returns the Class of the actual Score implementation
HardSoftDoubleScore	parseScore(String scoreString) Parses the String and returns a Score.
void	setHardScoreTimeGradientWeight(double hardScoreTimeGradientWeight) It's recommended to use a number which can be exactly represented as a double, such as 0.5, 0.25, 0.75, 0.125, ... but not 0.1, 0.2, ...
