Figure 3.22.
An initial population and its later descendants created, via gene
transposition and gene recombination, to solve the Majority(
a
,
b
,
c
) function
problem. The chromosomes encode sub-ETs linked by OR. Note that the perfect
solution found in generation 8 (chromosome 3) has a duplicated gene (genes 1
and 2). The ancestor genes of this individual were traced back to generation 0 and
all their descendants are shown. Note how these genes got scattered throughout
the genome, jumping to all conceivable places and often becoming duplicated.
