public class SeeAcceptabilityReasoner
extends AbstractAcceptabilityReasoner

Implements the SEE approach ("selective extension enumeration") to determine the set of acceptable arguments of an AF wrt. complete/preferred/stable semantics and credulous reasoning and wrt. stable semantics and skeptical reasoning , cf. [Thimm, Cerutti, Vallati; COMMA 2020]. It iteratively calls a SAT solver to discover new acceptable arguments.

public SeeAcceptabilityReasoner(SatSolver satSolver,
 Semantics semantics,
 InferenceMode inferenceMode)

Creates a new IaqAcceptabilityReasoner.

Parameters:

satSolver - some SatSolver.

semantics - either Semantics.CO, Semantics.PR, or Semantics.ST

inferenceMode - either InferenceMode.CREDULOUS or InferenceMode.SKEPTICAL (only stable semantics)

Method Details

getAcceptableArguments

public Collection<Argument> getAcceptableArguments(DungTheory aaf)

Description copied from class: AbstractAcceptabilityReasoner

Returns the set of acceptable arguments of this reasoner.

Specified by:

getAcceptableArguments in class AbstractAcceptabilityReasoner

Parameters:

aaf - some AAF

Returns:

the set of acceptable arguments of this reasoner.

isInstalled

public boolean isInstalled()

the solver is natively installed and is therefore always installed

Returns:

`true` if the solver is installed and available, `false` otherwise.
