AP, is a mapping from set of individuals into set of posssible programs. Individuals
in population and used by AP consist of non-numerical expressions (operators, func
tions, .), as described above, which are in the evolutionary process represented by their
integer position indexes (Fig 7.6). This index then serves as a pointer into the set of
