Constructor Details

DefaultDungTheoryGenerator

public DefaultDungTheoryGenerator(DungTheoryGenerationParameters params)

Creates a new generator with the given parameters.

Parameters:

params - some generation parameters.

DefaultDungTheoryGenerator

public DefaultDungTheoryGenerator(int numberOfArguments,
 double attackProbability)

Creates a new generator with the given parameters.

Parameters:

numberOfArguments - the number of arguments.

attackProbability - the probability that there is an attack between any two arguments

Method Details

next

public DungTheory next()

Specified by:

next in interface BeliefSetIterator<Argument,DungTheory>

Specified by:

next in interface DungTheoryGenerator

Specified by:

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,

setSeed

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.

toString

public String toString()

Overrides:

toString in class Object

hasNext

public boolean hasNext()

Specified by:

hasNext in interface BeliefSetIterator<Argument,DungTheory>
