Class StableHeuristic

java.lang.Object
  org.dllearner.algorithms.el.StableHeuristic

All Implemented Interfaces:

Comparator<SearchTreeNode>, ELHeuristic

public class StableHeuristic
extends Object
implements ELHeuristic

A stable comparator for search tree nodes. Stable means that the order of nodes will not change during the run of the learning algorithm. In this implementation, this is ensured by using only covered examples and tree size as criteria.
