A list of requirements for a genetic programming
representation is put forward and a representation
separating the genotype and phenotype
with a linear genome is presented.
The target language for the genetic program
is Perl. The mapping process, between the
genotype and phenotype, converts blocks of
four genes into program statements. This
process is context-free and therefore provides
inheritable characteristics. The representation
is tested by evolving a selection of list
evaluation and manipulation functions which
are all evolved from the same language subset,
with good results
