| The fitness of any individual is the sum of win/loss
records against 15 opponents from an enemy population. If a > S(i) then
a wins and gets one fitness point, otherwise its fitness remains unchanged.
With both populations starting at 0, we see both populations climbing steadily
toward objective maximum. The large sample_size keeps the populations engaged
(in constant competition), driving both upward. Since everyone competes
with a large sample of players, any improvement in one population allows
for selection and therefore improvement in the other population. |
