All Implemented Interfaces:

Iterator<DungTheory>, DungTheoryGenerator, BeliefSetIterator<Argument,DungTheory>

public class EnumeratingDungTheoryGenerator
extends Object
implements DungTheoryGenerator

This generator generators all possible Dung argumentation theories. It starts with the argumentation frameworks just consisting of one arguments and then increases their size.

next in interface Iterator<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,
