Figure 3.33.
Best individual of generation 7 (chromosome 12). It has a fitness of
989.9987 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 previous best of generation individuals (see
Figures 3.31 and 3.32).
c)
The corresponding mathematical expression after linking
with addition (the contribution of each sub-ET is shown in brackets).
