public class SimpleStableReasoner
extends AbstractExtensionReasoner

This reasoner for Dung theories performs inference on the stable extensions. Computes the set of all stable extensions, i.e., all conflict-free sets that attack each other argument. For that, it uses the SimpleSccCompleteReasoner to first compute all complete extensions, and then filters out the non-stable ones.

public SimpleStableReasoner()

Method Details

getModels

public Collection<Extension<DungTheory>> getModels(DungTheory bbase)

Description copied from interface: ModelProvider

Returns a characterizing model of the given belief base

Parameters:

bbase - some belief base

Returns:

the (selected) models of the belief base

getModel

public Extension<DungTheory> getModel(DungTheory 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.

Parameters:

bbase - some belief base

Returns:

a selected model of the belief base.
