public class WeaklyCompleteReasoner
extends AbstractExtensionReasoner

Reasoner for weakly complete semantics as described in: see: Baumann, Brewka, Ulbricht: Revisiting the foundations of abstract argumentation-semantics based on weak admissibility and weak defense. a set of arguments E is w-complete iff it is w-admissible and there exists no superset of E that is w-defended by E

WeaklyCompleteReasoner

public WeaklyCompleteReasoner()

Method Details

getModels

public Collection<Extension<DungTheory>> getModels(DungTheory bbase)

Description copied from interface: ModelProvider

Returns a characterizing model of the given belief base

Parameters:

bbase - some belief base

Returns:

the (selected) models of the belief base

getModel

public Extension<DungTheory> getModel(DungTheory bbase)

Description copied from interface: ModelProvider

Returns a single (dedicated) model of the given belief base. If the implemented method allows for more than one dedicated model, the selection may be non-deterministic.

Parameters:

bbase - some belief base

Returns:

a selected model of the belief base.

isWeaklyDefendedBy

public boolean isWeaklyDefendedBy(Collection<Argument> X,
 Collection<Argument> E,
 DungTheory theory)

Computes whether E w-defends X i.e. for every attacker y of X: 1. E attacks y or 2. y is not in any w-admissible set of the E-reduct of theory, y is not in E and there exists a superset of X that is w-admissible in theory

Parameters:

X - a set of arguments

E - a set of arguments

theory - a dung theory

Returns:

true, if E w-defends X
