Class JGAPClient

java.lang.Object
  java.lang.Thread
      org.jgap.distr.grid.JGAPClient

All Implemented Interfaces:

java.lang.Runnable

public class JGAPClient
extends java.lang.Thread

A client defines work for the grid and sends it to the JGAPServer. Use this class to get an idea for your grid client implementation or see the samples under package examples.grid to have templates for a) fitness computation and b) evolution on the worker side.

Since:

3.01
