public class ContensionSatInconsistencyMeasure
extends SatBasedInconsistencyMeasure
```
This class implements a SAT encoding of the contension inconsistency measure, originally proposed in [Grant, Hunter. "Measuring consistency gain and information loss in step-wise inconsistency resolution", ECSQARU'11].
This measure is defined on paraconsistent models (three-valued models with truth values F,T,B) of a knowledge base by taking the minimal number of B-valued propositions needed in a model of the knowledge base.
