Class EvolveJob

java.lang.Object
  org.jgap.impl.job.JobBase
      org.jgap.impl.job.EvolveJob

All Implemented Interfaces:

java.io.Serializable, java.lang.Runnable, IEvolveJob, IJob

public class EvolveJob
extends JobBase
implements IEvolveJob

A job that evolves a population. The evolution takes place as given by the configuration. It operates on a population also provided. This class utilizes sub jobs to perform its sub-tasks. Each sub job may either be a local implementation satisfying the IJob interface. Or it may be a job that eventually is put onto the grid and returns with a result!
