public class PodlaszewskiCaminadaDungTheoryGenerator extends java.lang.Object implements DungTheoryGenerator
This generator generates abstract argumentation frameworks following the schema described in "Strong Admissibility Revisited" (COMMA2014) by Martin Caminda, following and idea by Mikolay Podlaszewski. These frameworks are supposedly hard for computing grounded semantics.- Author:

public DungTheory next(Argument arg)
Description copied from interface:DungTheoryGenerator
Generates a new Dung theory where the given argument is enforced to be in the grounded extension- Specified by:

- Parameters:
arg
- an argument that is enforced to be in the grounded extension of the generated theory.- Returns:
- a Dung theory,
