Class DrasticDistance<T extends Interpretation<B,S>,B extends BeliefBase,S extends Formula>

java.lang.Object

net.sf.tweety.commons.analysis.DrasticDistance<T,B,S>

Type Parameters:

T - The actual type of interpretation

All Implemented Interfaces:

InterpretationDistance<T,B,S>

public class DrasticDistance<T extends Interpretation<B,S>,B extends BeliefBase,S extends Formula>
extends java.lang.Object
implements InterpretationDistance<T,B,S>

This class models the drastic distance measure between interpretations, see [Grant, Hunter. Distance-based Measures of Inconsistency, ECSQARU'13]. It returns 0 if the interpretations are equivalent and 1 otherwise.
