The table shows that the method can be very effective even if the individual functions do not tend to zero at the minimum. The number of function values quoted for 8 = 0 is less than the corresponding number in Table 1, because the minimum is better determined in the experiment, as there are twice as many functions as variables. This paper would not be complete without the example showing the effect of the procedure on Rosenbrock's (1960) minimization problem
