Figure 21 shows the progress of a GA on the two-dimensional Rosenbrock function, . This is presented purely for purposes of comparison. Each member of the 1st, 10th, 20th and 30th generations is shown (by a symbol). The convergence of the population to the neighborhood of the optimum at is readily apparent.
