Method Detail

query

public java.lang.Boolean query(ClBeliefSet beliefbase,
                               PlFormula formula)

Description copied from interface: Reasoner

Queries the given belief base for the given formula.

Specified by:

query in interface QualitativeReasoner<ClBeliefSet,PlFormula>

Specified by:

query in interface Reasoner<java.lang.Boolean,ClBeliefSet,PlFormula>

Parameters:

beliefbase - a belief base

formula - a formula

Returns:

the answer to the query

getModels

public java.util.Collection<RankingFunction> getModels(ClBeliefSet bbase)

Description copied from interface: ModelProvider

Returns a characterizing model of the given belief base

Specified by:

getModels in interface ModelProvider<Conditional,ClBeliefSet,RankingFunction>

Parameters:

bbase - some belief base

Returns:

the (selected) models of the belief base

getModel

public abstract RankingFunction getModel(ClBeliefSet bbase)

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<Conditional,ClBeliefSet,RankingFunction>

Parameters:

bbase - some belief base

Returns:

a selected model of the belief base.
