Class ImSafeFormulaIndependence

java.lang.Object

net.sf.tweety.logics.pl.postulates.ImPostulate

net.sf.tweety.logics.pl.postulates.ImSafeFormulaIndependence

All Implemented Interfaces:

net.sf.tweety.commons.postulates.Postulate<PlFormula>

public class ImSafeFormulaIndependence
extends ImPostulate

The "safe-formula independence" postulate for inconsistency measures: Removing a safe formula (i.e. a consistent formula whose signature is disjoint from the signature of the rest of the knowledge base) from the knowledge base does not change its inconsistency value.
