Class SimpleDoubleScoreDefinition

java.lang.Object

org.optaplanner.core.impl.score.definition.AbstractScoreDefinition<SimpleDoubleScore>

org.optaplanner.core.impl.score.buildin.simpledouble.SimpleDoubleScoreDefinition

All Implemented Interfaces:

Serializable, ScoreDefinition<SimpleDoubleScore>

Deprecated.

Double-based scores are deprecated as floating point numbers are not associative (A + B + C == C + B + A) and therefore they are not compatible with incremental score calculation.

Method Detail

getLevelsSize

public int getLevelsSize()

Deprecated.

Description copied from interface: ScoreDefinition

Returns the length of Score.toLevelNumbers() for every Score of this definition. For example: returns 2 on HardSoftScoreDefinition.

Specified by:

getLevelsSize in interface ScoreDefinition<SimpleDoubleScore>

Overrides:

getLevelsSize in class AbstractScoreDefinition<SimpleDoubleScore>

Returns:

at least 1

getFeasibleLevelsSize

public int getFeasibleLevelsSize()

Deprecated.

Description copied from interface: ScoreDefinition

Returns the number of levels of Score.toLevelNumbers(). that are used to determine Score.isFeasible().

Returns:

at least 0, at most ScoreDefinition.getLevelsSize()

getScoreClass

public Class<SimpleDoubleScore> getScoreClass()

Deprecated.

Description copied from interface: ScoreDefinition

Returns the Class of the actual Score implementation. For example: returns HardSoftScore.class on HardSoftScoreDefinition.

Returns:

never null

getZeroScore

public SimpleDoubleScore getZeroScore()

Deprecated.

Description copied from interface: ScoreDefinition

The score that represents zero.

Returns:

never null

getOneSoftestScore

public SimpleDoubleScore getOneSoftestScore()

Deprecated.

Description copied from interface: ScoreDefinition

The score that represents the softest possible one.

Returns:

never null

parseScore

public SimpleDoubleScore parseScore(String scoreString)

Deprecated.

Description copied from interface: ScoreDefinition

Deprecated.

Description copied from interface: ScoreDefinition

The opposite of Score.toLevelNumbers().

Parameters:

initScore - <= 0, managed by OptaPlanner, needed as a parameter in the Score's creation method, see Score.getInitScore()

levelNumbers - never null

Returns:

never null

buildScoreInliner

public ScoreInliner<SimpleDoubleScore> buildScoreInliner(boolean constraintMatchEnabled)

Deprecated.

Description copied from interface: ScoreDefinition

Used by BavetConstraintFactory

Parameters:

constraintMatchEnabled - true if ScoreDirector.isConstraintMatchEnabled() should be true

Returns:

never null

buildScoreHolder

public ScoreHolder buildScoreHolder(boolean constraintMatchEnabled)

Deprecated.

Description copied from interface: ScoreDefinition

Used by DroolsScoreDirector.

Parameters:

constraintMatchEnabled - true if ScoreDirector.isConstraintMatchEnabled() should be true

Returns:

never null

buildOptimisticBound

public SimpleDoubleScore buildOptimisticBound(InitializingScoreTrend initializingScoreTrend,
                                              SimpleDoubleScore score)

Deprecated.

Description copied from interface: ScoreDefinition

Builds a Score which is equal or better than any other Score with more variables initialized (while the already variables don't change).

Parameters:

initializingScoreTrend - never null, with InitializingScoreTrend.getLevelsSize() equal to ScoreDefinition.getLevelsSize().

score - never null, with Score.getInitScore() 0.

Returns:

never null

buildPessimisticBound

                                               SimpleDoubleScore score)

Deprecated.

Description copied from interface: ScoreDefinition

Builds a Score which is equal or worse than any other Score with more variables initialized (while the already variables don't change).

Parameters:

initializingScoreTrend - never null, with InitializingScoreTrend.getLevelsSize() equal to ScoreDefinition.getLevelsSize().

score - never null, with Score.getInitScore() 0

Returns:

divideBySanitizedDivisor

public SimpleDoubleScore divideBySanitizedDivisor(SimpleDoubleScore dividend,
                                                  SimpleDoubleScore divisor)

Deprecated.

Description copied from interface: ScoreDefinition

Return Score whose every level is the result of dividing the matching levels in this and the divisor. When rounding is needed, it is floored (as defined by Math.floor(double)).

If any of the levels in the divisor are equal to zero, the method behaves as if they were equal to one instead.

divisor - value by which this Score is to be divided

Returns:

this / divisor
