Figure 3.32.
Best individual of generation 2 (chromosome 8). It has a fitness of
945.8432 evaluated against the set of fitness cases presented in Table 3.2.
a)
The
chromosome of the individual.
b)
The sub-ETs codified by each gene. Note that
sub-ET
2
was already present in the best individual of generation 0 (see Figure
3.31).
c)
The corresponding mathematical expression after linking with addition (the
contribution of each sub-ET is shown in brackets). Note again the existence
of a neutral gene (gene 1) encoding zero.
