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.
