public class VacuousReductReasoner extends AbstractExtensionReasoner
Implements a general vacuous reduct reasoner, as proposed in [Thimm. On Undisputed Sets in Abstract Argumentation. AAAI2023] Given a base reasoner A and a reduct reasoner B, a set E is an extension wrt. to vacuous reduct semantics, if E is a A-extension and the corresponding E-reduct does not contain a non-empty B-extension.

  • Constructor Details

    • VacuousReductReasoner

      public VacuousReductReasoner(AbstractExtensionReasoner baseReasoner, AbstractExtensionReasoner reductReasoner)
      Creates a new VacuousReductReasoner with the given base and reduct reasoners.
      Parameters:
      baseReasoner - some extension reasoner
      reductReasoner - some extension reasoner

  • 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.
