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.
