Reduct-Admissibility Principle

A semantics satisfies reduct admissibility iff for every AF F and every extension E we have: For all arguments a in E: if an argument b attacks a, then b is in no extension of the E-reduct of F

public ReductAdmissibilityPrinciple()

Method Details

getName

public String getName()

Description copied from interface: Postulate

The textual name of the postulate

Returns:

a string

isApplicable

public boolean isApplicable(Collection<Argument> kb)

Description copied from interface: Postulate

Checks whether the given kb represents a non-trivial instance for this postulate, i.e., whether assumptions of this postulates are satisfied (evaluating an approach on a non-applicable instance always succeeds).

Specified by:

isApplicable in interface Postulate<Argument>

Specified by:

isApplicable in class Principle

Parameters:

kb - some knowledge base

Returns:

true if the knowledge base is a non trivial instance of this postulate.

isSatisfied

public boolean isSatisfied(Collection<Argument> kb,
 AbstractExtensionReasoner ev)

Description copied from class: Principle

Computes whether the given extension reasoner (i.e. semantics) satisfies this principle for this specific instance

Specified by:

isSatisfied in class Principle

Parameters:

kb - some argumentation framework

ev - an extension reasoner

Returns:

true, if this principle is satisfied for this instance and semantics
