ImSafeFormulaIndependence

java.lang.Object
- net.sf.tweety.logics.pl.postulates.ImPostulate
- - net.sf.tweety.logics.pl.postulates.ImSafeFormulaIndependence

All Implemented Interfaces:

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.

Modifier Constructor Description

protected ImSafeFormulaIndependence()
Protected constructor so one uses only the single instance ImPostulate.SAFEFORMULAINDEPENDENCE

Method Summary

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

    Description copied from interface: Postulate
    
    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).
    
    Specified by:
    
    isApplicable in interface Postulate<PlFormula>
    
    Specified by:
    
    isApplicable in class ImPostulate
    
    Parameters:
    
    kb - some knowledge base
    
    Returns:
    
    true if the knowledge base is a non trivial instance of this postulate.
