public abstract class SerialisableExtensionReasoner
extends AbstractExtensionReasoner

Abstract class for computing extensions via a serialised transition system to implement this class, you need to define a selection and a termination function Selection function a(UA, UC, C): selects and returns a subset of the initial sets Termination function b((AF, S)): If the given state satisfies a specific condition, its extension may be accepted by the associated serialised semantics

SerialisableExtensionReasoner

public SerialisableExtensionReasoner()

Method Details

selectionFunction

public abstract Collection<Extension<DungTheory>> selectionFunction(Collection<Extension<DungTheory>> unattacked,
 Collection<Extension<DungTheory>> unchallenged,
 Collection<Extension<DungTheory>> challenged)

select a subset of the initial sets of the theory, i.e. the possible successor states

Parameters:

unattacked - the set of unattacked initial sets

unchallenged - the set of unchallenged initial sets

challenged - the set of challenged initial sets

Returns:

a subset of the initial sets of the theory, selected via a specific criteria

terminationFunction

public abstract boolean terminationFunction(TransitionState state)

Checks whether the current state satisfies some condition, i.e. its extension can be accepted by the corresponding semantics

Parameters:

state - the current state of the transition system

Returns:

true, if the state satisfies the condition

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.

getSerialisableReasonerForSemantics

public static SerialisableExtensionReasoner getSerialisableReasonerForSemantics(Semantics semantics)

Creates a reasoner for the given semantics.

Parameters:

semantics - a semantics

Returns:

a reasoner for the given Dung theory, inference type, and semantics
