Class PodlaszewskiCaminadaDungTheoryGenerator

java.lang.Object

net.sf.tweety.arg.dung.util.PodlaszewskiCaminadaDungTheoryGenerator

All Implemented Interfaces:

java.util.Iterator<DungTheory>, DungTheoryGenerator, BeliefSetIterator<Argument,DungTheory>

public class PodlaszewskiCaminadaDungTheoryGenerator
extends java.lang.Object
implements DungTheoryGenerator

This generator generates abstract argumentation frameworks following the schema described in "String Admissibility Revisited" (COMMA2014) by Martin Caminda, following and idea by Mikolay Podlaszewski. These frameworks are supposedly hard for computing grounded semantics.

Field Detail

numComponents

private int numComponents

The number of components in the generated frameworks.

Constructor Detail

PodlaszewskiCaminadaDungTheoryGenerator

public PodlaszewskiCaminadaDungTheoryGenerator(int numComponents)

Creates a new generator that generates frameworks of the given numComponents >= 0. More precisely, the number of arguments in these frameworks have 4 + numComponents*4 arguments.

Parameters:

numComponents - the number of components

Method Detail

next

public DungTheory next()

Specified by:

next in interface java.util.Iterator<DungTheory>

Specified by:

next in interface DungTheoryGenerator

Specified by:

next in interface BeliefSetIterator<Argument,DungTheory>

next

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:

next in interface DungTheoryGenerator

Parameters:

arg - an argument that is enforced to be in the grounded extension of the generated theory.

Returns:

a Dung theory,

setSeed

public void setSeed(long seed)

Description copied from interface: DungTheoryGenerator

Set the seed for the generation. Every two runs of generations with the same seed are ensured to be identical.

Specified by:

setSeed in interface DungTheoryGenerator

Parameters:

seed - some seed.

hasNext

public boolean hasNext()

Specified by:

hasNext in interface java.util.Iterator<DungTheory>

Specified by:

hasNext in interface DungTheoryGenerator

Specified by:

hasNext in interface BeliefSetIterator<Argument,DungTheory>
