public class RedBlackExperiment
extends Experiment
implements java.io.Serializable

This class models the red and black experiment. A player bets on a sequence of Bernoulli trials at even stakes. The player starts with an intial fortune and must quit when she is either ruined or reaches a target fortune. The initial and target fortunes can be varied as well as the probability of success. Either of two classical strategies can be chosen: bold play or timid play.
