CspInconsistencyMeasure

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

Type Parameters:

S - The specific type of formulas

All Implemented Interfaces:

PostulateEvaluatable<S>, InconsistencyMeasure<BeliefSet<S,?>>
```
public class CspInconsistencyMeasure<S extends Formula>
extends BeliefSetInconsistencyMeasure<S>
```
This class implements the inconsistency measure I_CSP from [Said Jabbour, Yue Ma, Badran Raddaoui, Lakhdar Sais, Yakoub Salhi. On Structure-Based Inconsistency Measures and Their Computations via Closed Set Packing. AAMAS 2015] The measure is implemented using an integer programming approach sketched in the above paper. Note that this measure is equivalent to I_W from [Said Jabbour and Yue Ma and Badran Raddaoui and Lakhdar Sais and Yakoub Salhi. A MIS Partition Based Framework for Measuring Inconsistency. KR 2016]
