DMaxInconsistencyMeasure

java.lang.Object
- net.sf.tweety.logics.commons.analysis.BeliefSetInconsistencyMeasure<S>
- - net.sf.tweety.logics.commons.analysis.DMaxInconsistencyMeasure<T,B,S>

Type Parameters:

T - the type of interpretations

B - the type of belief bases

S - The type of formulas supported

All Implemented Interfaces:

PostulateEvaluatable<S>, InconsistencyMeasure<BeliefSet<S,?>>
```
public class DMaxInconsistencyMeasure<T extends Interpretation<B,S>,B extends BeliefBase,S extends Formula>
extends BeliefSetInconsistencyMeasure<S>
```
This class implements the d-max inconsistency measure from [Grant, Hunter. Distance-based Measures of Inconsistency, ECSQARU'13]. This implementation uses a slightly different characterization than the one used in the paper. This measure seeks an interpretation I such that the the maximal distance between every formula of the knowledge base and I is minimal. The value of the inconsistency is than exactly this value. The distance can be parameterized.
NOTE: Currently, this algorithm uses a brute force approach (checking all interpretations) for computing the solution.
