Effects of noisy fitness Evaluation Undesirable selection Behavior a superior candidate may be erroneously believed to be inferior, causing it to be eliminated An inferior candidate may be erroneously believed to be superior, causing it to survive and reproduce. Undesirable effects The system does not retain what it has learnt. Exploitation is limited Fitness does not monotonically improve with generation The learning rate is reduced 1.
