All Implemented Interfaces:

CaseListRefiner, java.io.Serializable

public class ThresholdCaseListRefiner
extends AbstractCaseListRefiner

In refining a case list, the difference between each case and the current problem is calculated. Those that are above a threshold are removed from further consideration in this episode. Remaining cases are ordered by distance from the problem, shortest distance first.
