Class JoinedCostConvergerWithFinalAutoFilterStep

java.lang.Object

com.dna.jopt.util.costconverger.AbstractCostConverger

com.dna.jopt.util.costconverger.JoinedCostConvergerWithFinalAutoFilterStep

All Implemented Interfaces:

ICostConverger

public class JoinedCostConvergerWithFinalAutoFilterStep
extends AbstractCostConverger

This class is an extension of AbstractCostConverger and defines convergence (unchanged joined cost over several iterations). After convergence has been achieved the optimization is stopped.

Constructor Detail

JoinedCostConvergerWithFinalAutoFilterStep

public JoinedCostConvergerWithFinalAutoFilterStep(IOptimization opti)

The constructor in order to set convergence by joined cost. After convergence is achieved the optimization is stopped.

Implementation example:

 ICostConverger myJoinedCostConverger = new JoinedCostConverger(this);
    myJoinedCostConverger.addExecutionAlgorithm(GeneticEvolutionAlgo.MY_TITLE);
    myJoinedCostConverger.setConvergenceThreshold(5);
 

Parameters:

opti - the iOptimization to check for convergence
