public abstract class SerialisableExtensionReasoner
extends AbstractExtensionReasoner

Ancestor class for serialisable AF reasoners

A serialisable reasoner is defined via the following two methods:
Selection function a(UA, UC, C): Return a subset of the initial sets.
Termination function b((AF, S)): True, if S is an extension.

Constructor Details

SerialisableExtensionReasoner

public SerialisableExtensionReasoner(Semantics semantics)

Constructs a serialisable extension reasoner for the given semantics

Parameters:

semantics - the semantics of this reasoner

Method Details

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.

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

getSequences

public Collection<SerialisationSequence> getSequences(DungTheory bbase)

Computes the set of serialisation sequences that each correspond to some extension wrt. the semantics of this reasoner.

Parameters:

bbase - some argumentation framework

Returns:

the set of serialisation sequences computed by the reasoner

getSemantics

public Semantics getSemantics()

Return the semantics of this reasoner

Returns:

The semantics of this reasoner

terminationFunction

public abstract boolean terminationFunction(DungTheory theory,
 Extension<DungTheory> extension)

Determines whether the current state represents an extension wrt. the semantics of the reasoner or not.

Parameters:

theory - The current framework of the transition system

extension - The extension constructed so far

Returns:

true, if the state satisfies the termination condition of the semantics

getSerialisationGraph

public SerialisationGraph getSerialisationGraph(DungTheory bbase)

Creates a graph, visualizing the transition states of the serialisation process, which creates all serialisable extensions according to the specified semantics of the specified framework.

Parameters:

bbase - argumentation framework, for which the extensions shall be computed

Returns:

Graph representing the serialisation sequences

getSerialisableReasonerForSemantics

public static SerialisableExtensionReasoner getSerialisableReasonerForSemantics(Semantics semantics)

Returns a reasoner for the given semantics.

Parameters:

semantics - a semantics

Returns:

a serialisable extension reasoner for the given semantics
