Method Details

query

public Boolean query(ClBeliefSet beliefbase,
 PlFormula formula)

Description copied from interface: QualitativeReasoner

Queries the given belief base with the provided formula and returns a boolean result. The result indicates whether the formula is entailed or satisfied by the belief base according to the qualitative reasoning method implemented by the reasoner.

Specified by:

query in interface QualitativeReasoner<ClBeliefSet,PlFormula>

Specified by:

query in interface Reasoner<Boolean,ClBeliefSet,PlFormula>

Parameters:

beliefbase - The belief base to be queried.

formula - The formula for which the query is made.

Returns:

`TRUE` if the formula is entailed or satisfied by the belief base, `FALSE` otherwise.

getModels

public 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.
