MaInconsistencyMeasure

java.lang.Object
- net.sf.tweety.logics.commons.analysis.BeliefSetInconsistencyMeasure<S>
- - net.sf.tweety.logics.commons.analysis.MaInconsistencyMeasure<S>

Type Parameters:

S - the type of formulas

All Implemented Interfaces:

PostulateEvaluatable<S>, InconsistencyMeasure<BeliefSet<S,?>>
```
public class MaInconsistencyMeasure<S extends Formula>
extends BeliefSetInconsistencyMeasure<S>
```
This class models the I_M inconsistency measure from e.g. [Grant,Hunter,2011a]. It takes as inconsistency value the number of maximal consistent subsets plus the number of formulas that are self-contradicting minus 1.
