The implementation of any EA begins with the encoding of the
problem solutions. Binary encoding is frequently used, but, as dis-
cussed earlier, real number encoding (e.g. using physicochemical
properties) provides a more natural representation of the problem.
Regardless of the encoding type, a coded problem solution is referred
to as the
genotype
and can be used to determine the decoded pheno-
type. The
genotype
can also be called a
chromosome
, and consists of a

tions (uniform, one point and two point). Color shades indicate the parts of
the genes coming from respective parents.
