All Implemented Interfaces:

BaseRevisionOperator<ASPRule>

public class ParameterisedArgumentativeSelectiveRevisionOperator
extends MultipleBaseRevisionOperator<ASPRule>

This class represents a selective revision using the base revision approach from [1] for the inner revision and the sceptical argumentative transformation function from [2]. The selective revision operator is parameterised by two notions of attack used by the argumentation framework utilised by the transformation function. In [2] it is shown that there are at least 5 classes of distinct plausible instantiations of this operator: a/a, d/d, sa/sa, sa/a, and ca/ca where "a" stands for Attack, "d" for Defeat, "sa" for Strong Attack and "ca" for Confident Attack.
