All Implemented Interfaces:

Postulate<Argument>

public class RaDefensePrecedence
extends RankingPostulate

The "defense precedence" postulate for ranking semantics as proposed in [Amgoud, Ben-Naim. Ranking-based semantics for argumentation frameworks. 2013]: For two arguments with the same number of direct attackers, a defended argument is ranked higher than a non-defended argument.

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).
