Class LocalHillTLC

java.lang.Object
  org.jscience.architecture.traffic.algorithms.tlc.TLController
      org.jscience.architecture.traffic.algorithms.tlc.LocalHillTLC

All Implemented Interfaces:

Colearning, TwoStageLoader, XMLSerializable

public class LocalHillTLC
extends TLController
implements Colearning

This controller will decide it's Q values for the traffic lights according to the traffic situation on / the lane connected to the TrafficLight. It will learn how to alter it's outcome by reinforcement learning.
