•        This plot shows the performance of learning algorithm for 1 serve over 30,000 trials
•         Plota  where
•     a=1 refers to successful shots => reaching the ball
•     a=2 refers to completely successful shots => hitting a correct shot as well
•  Here
•    Gamma = 0.9
•    Lambda = 0.95
•    Reward Function  = 4 for complete success
                                                               = 2  for partial success
                                                               = -1 for failure
                                                               = 0 otherwise
