Class TC2B1

java.lang.Object
  org.jscience.architecture.traffic.algorithms.tlc.TLController
      org.jscience.architecture.traffic.algorithms.tlc.TC2B1

All Implemented Interfaces:

Colearning, InstantiationAssistant, TwoStageLoader, XMLSerializable

public class TC2B1
extends TLController
implements Colearning, InstantiationAssistant

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. TC2 According to Garp, eh, Jilles
