java.lang.Object

org.tweetyproject.beliefdynamics.MultipleBaseRevisionOperator<T>

org.tweetyproject.beliefdynamics.LeviMultipleBaseRevisionOperator<T>

Type Parameters:

T - the type of formulas this operators works on.

All Implemented Interfaces:

BaseRevisionOperator<T>

public class LeviMultipleBaseRevisionOperator<T extends ClassicalFormula>
extends MultipleBaseRevisionOperator<T>

This class implements the Levi identity for multiple revision, ie. an revision that is composed of the contraction with the negated set of formulas and then expansion with those formulas.
