public class PmInconsistencyMeasure
extends BeliefSetInconsistencyMeasure<PlFormula>

This class implements the inconsistency measure I_{P_m} proposed in [Jabbour, Raddaoui. Measuring Inconsistency Through Minimal Proofs. ECSQARU 2013]. The implementation here follows the characterization of I_{P_m} using Proposition 9 in the above paper. There, I_{P_m} (K)= \sum_{x\in Var(K)}|Pm(x)|*|Pm(-x)| where Pm(x) is the set of all (not necessarily consistent) minimal proofs of x in K that mention x.
