Constructor Details

MeanDistanceCulpabilityMeasure

public MeanDistanceCulpabilityMeasure(OptimizationRootFinder rootFinder,
 boolean normalized)

Creates a new measure.

Parameters:

rootFinder - a root finder

normalized - whether this measure uses the normalized mindev measure.

Method Details

culpabilityMeasure

public Double culpabilityMeasure(PclBeliefSet beliefSet,
 ProbabilisticConditional conditional)

Description copied from interface: CulpabilityMeasure

Returns the degree of responsibility of the given formula to cause inconsistency in the given belief set (NOTE: the formula should be in the given belief set).

Specified by:

culpabilityMeasure in interface CulpabilityMeasure<ProbabilisticConditional,PclBeliefSet>

Specified by:

culpabilityMeasure in interface SignedCulpabilityMeasure

Parameters:

beliefSet - a belief set.

conditional - a formula

Returns:

a Double indicating the degree of inconsistency (NOTE: if the given formula does not appear in the given belief set the degree is defined to be zero).

sign

public Double sign(PclBeliefSet beliefSet,
 ProbabilisticConditional conditional)

Description copied from interface: SignedCulpabilityMeasure

Determines the sign of the culpability of the given conditional in the given belief set, i.e. one of {-1,0,1}.

Specified by:

sign in interface SignedCulpabilityMeasure

Parameters:

beliefSet - a belief set

conditional - a conditional

Returns:

one of {-1,0,1}
