org.tweetyproject.arg.dung.principles.DirectionalityPrinciple
All Implemented Interfaces:
Postulate<Argument>
public class DirectionalityPrinciple extends Principle
Directionality Principle A semantics satisfies directionality if for every unattacked set U in a dung theory F it holds that: The extensions of F restricted to U are equal to the extensions of F intersected with U see: Baroni, P., and Giacomin, M. (2007). On principle-based evaluation of extension-based argumentation semantics.

  • Method Details

    • getName

      public String getName()
      Description copied from interface: Postulate
      The textual name of the postulate
      Returns:
      a string

    • isApplicable

      public boolean isApplicable(Collection<Argument> kb)
      Description copied from interface: Postulate
      Checks whether the given kb represents a non-trivial instance for this postulate, i.e., whether assumptions of this postulates are satisfied (evaluating an approach on a non-applicable instance always succeeds).
      Specified by:
      isApplicable in interface Postulate<Argument>
      Specified by:
      isApplicable in class Principle
      Parameters:
      kb - some knowledge base
      Returns:
      true if the knowledge base is a non trivial instance of this postulate.

    • isSatisfied

      public boolean isSatisfied(Collection<Argument> kb, AbstractExtensionReasoner ev)
      Description copied from class: Principle
      *description missing*
      Specified by:
      isSatisfied in class Principle
      Parameters:
      kb - kb
      ev - ev
      Returns:
      is Satisfied
