Class HsInconsistencyMeasure<S extends net.sf.tweety.commons.Formula>

java.lang.Object

net.sf.tweety.logics.commons.analysis.BeliefSetInconsistencyMeasure<S>

net.sf.tweety.logics.commons.analysis.HsInconsistencyMeasure<S>

Type Parameters:

S - some formula type

T - some belief set type

All Implemented Interfaces:

InconsistencyMeasure<net.sf.tweety.commons.BeliefSet<S>>

public class HsInconsistencyMeasure<S extends net.sf.tweety.commons.Formula>
extends BeliefSetInconsistencyMeasure<S>

This class implements the Hitting Set inconsistency measure as proposed in [Thimm, 2014, in preparation]. The inconsistency value is defined as one plus the minimal number of interpretations, s.t. every formula of the belief set is satisfied by at least one interpretation. This is equivalent in the cardinality of a minimal partitioning of the knowledge base such that each partition is consistent.
