Genetic Neutrality in Naive Gene Expression Programming

Gene expression programming (
GEP
) is a genotype- phenotype system with non-coding regions in genome where possible neutral mutations would be accumulated. In this paper, a novel concept named naive gene expression programming (
NGEP
) is introduced. The main contributions include: (a) proposing a novel algorithm named
NGEP
, which decoding method based on the complete tree, (b) discussing the role of genetic neutrality in
GEP
and
NGEP
, and (c) performing experiments to show that
NGEP
is faster than traditional
GEP
, and the success rate of
NGEP
is higher than that in traditional
GEP
.
