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

java.lang.Object
org.tweetyproject.commons.analysis.DrasticDistance<T,B,S>
Type Parameters:
T - The actual type of interpretation
B - the type of belief bases
S - the type of formulas
All Implemented Interfaces:
InterpretationDistance<T,B,S>
public class DrasticDistance<T extends Interpretation<B,S>,B extends BeliefBase,S extends Formula> extends 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.
