All Implemented Interfaces:

```
public class RaAdditionOfAttackBranch
extends RankingPostulate
```
The "addition of attack branch" postulate for ranking semantics as formalized in [Bonzon, Delobelle, Konieczny, Maudet. A Comparative Study of Ranking-Based Semantics for Abstract Argumentation. 2016]: Adding an attack branch to any argument degrades its ranking. 'Adding an attack branch to the argument A' means adding the arguments {X1, ... , Xn} which are not in the original knowledge base, for whom is true that A <- X1 <- X2 ... <- Xn and where n is an odd number.

Method Summary

Modifier and Type	Method	Description
`java.lang.String`	`getName()`	The textual name of the postulate
`boolean`	`isApplicable(java.util.Collection<Argument> kb)`	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).
`boolean`	`isSatisfied(java.util.Collection<Argument> kb, AbstractRankingReasoner<ArgumentRanking> ev)`
