public class CircleInTheSquareEnvironment
extends SyntheticDataEnvironment

A synthetic environment for the circle-in-the-square problem. In this problem inputs are distributed in a two-dimensional square. The objective is to determine of weather a given point is located inside a circunsference laid on the center of the square. In this case, if the point belongs to the circle it will have `1' as output or `0' in the other case. $Id: CircleInTheSquareEnvironment.java,v 1.3 2005/03/24 17:59:54 supermarti Exp $
