If f(x ) < f(x); 8x 2 S; x 6= x ; then x is a strict global minimizer. In other instances, we may only nd an x 2 S that satis es f(x ) f(x); 8x 2 S \ Bx (")

By the so-called law of large numbers, the proportion of survivors L70=L55 tends to the individual survival probability 0:75 as the number of participants L55 tends to in nity. Therefore, as the
