Class MCRandomStateGenerator

java.lang.Object

burlap.domain.singleagent.mountaincar.MCRandomStateGenerator

All Implemented Interfaces:

StateGenerator

public class MCRandomStateGenerator
extends java.lang.Object
implements StateGenerator

Generates MountainCar states with the x-position between some specified range and the velocity between some specified range. By default, the ranges are the full ranges supported by the domain, but they can be individually changed.
