Description copied from class: AbstractSatExtensionReasoner

Returns the semantic-specific propositional characterization of the underlying Dung theory, see getPropositionalCharacterisation.

Specified by:

getPropositionalCharacterisationBySemantics in class AbstractSatExtensionReasoner

Parameters:

aaf - the Dung theory

in - propositional variables of in arguments.

out - propositional variables of out arguments.

undec - propositional variables of undec arguments.

Returns:

the semantic-specific propositional characterization of the underlying Dung theory, see getPropositionalCharacterisation.

query

public Boolean query(DungTheory beliefbase,
                     Argument formula,
                     net.sf.tweety.commons.InferenceMode inferenceMode)

Description copied from class: AbstractExtensionReasoner

Queries the given AAF for the given argument using the given inference type.

Overrides:

query in class AbstractExtensionReasoner

Parameters:

beliefbase - an AAF

formula - a single argument

inferenceMode - either InferenceMode.SKEPTICAL or InferenceMode.CREDULOUS

Returns:

"true" if the argument is accepted
