public class QualifiedReasoner extends AbstractExtensionReasoner
Reasoner for qualified sigma-semantics. If sigma is a scc-decomposable semantics this reasoner will compute the qualified extensions for the semantics. In qualified semantics a undecided argument x is treated as out. This means an argument y attacked by x and in a different scc can still be accepted(in). see: TODO add reference

  • Constructor Details

    • QualifiedReasoner

      public QualifiedReasoner(Semantics semantics)
      initialize reasoner with the given semantics as base function. Will only produce meaningful results if the given semantics is SCC-decomposable
      Parameters:
      semantics - a scc-decomposable semantics

    • QualifiedReasoner

      public QualifiedReasoner(AbstractExtensionReasoner reasoner)
      initialize reasoner with the given reasoner as base reasoner Will only produce meaningful results if the given semantics is SCC-decomposable
      Parameters:
      reasoner - a reasoner for a scc-decomposable semantics

  • 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.

    • isInstalled

      public boolean isInstalled()
      this method always returns true because the solver is native
      Specified by:
      isInstalled in interface QualitativeReasoner<DungTheory,Argument>
      Overrides:
      isInstalled in class AbstractExtensionReasoner
      Returns:
      if the solver is installed
