Accordingly, the task of recombination is to extract the genetic
information common to the selected individuals, as this information is
likely responsible for fitness increase.
A perfect recombination operator should additionally reduce those parts of the
which are responsible for a decrease in fitness.
This is, e.g., statistically realized by ES
operators in real-valued search spaces by (partially) averaging out
the defective components.
