These functions were optimized by MuGA configured with 128
MI in the main population. Selection is made by tournaments with
size 3. The operator selects 256 individuals for the mating pool,
and in this way MI with copies are guaranteed for the following
operators. Recombination is made by one point crossover operator
with probability 0.6. Rescaling was applied to maintain a
maximum total of copies in the main population of twice the
number of MI. These aspects of MuGA were kept constant over
all the experiments.
