Method Detail

query

public abstract java.lang.Double query(PclBeliefSet beliefbase,
                                       PropositionalFormula formula)

Description copied from interface: Reasoner

Queries the given belief base for the given formula.

Specified by:

query in interface Reasoner<java.lang.Double,PclBeliefSet,PropositionalFormula>

Parameters:

beliefbase - a belief base

formula - a formula

Returns:

the answer to the query

getModels

public abstract java.util.Collection<ProbabilityDistribution<PossibleWorld>> getModels(PclBeliefSet bbase)

Description copied from interface: ModelProvider

Returns a characterizing model of the given belief base

Specified by:

getModels in interface ModelProvider<ProbabilisticConditional,PclBeliefSet,ProbabilityDistribution<PossibleWorld>>

Parameters:

bbase - some belief base

Returns:

the (selected) models of the belief base

getModel

public abstract ProbabilityDistribution<PossibleWorld> getModel(PclBeliefSet beliefbase)

Description copied from interface: ModelProvider

Returns a single (dedicated) model of the given belief base. If the implemented method allows for more than one dedicated model, the selection may be non-deterministic.

Specified by:

getModel in interface ModelProvider<ProbabilisticConditional,PclBeliefSet,ProbabilityDistribution<PossibleWorld>>

Returns:

a selected model of the belief base.
