abstract = "This paper is concerned with the effect of the grammar
type on grammatical evolution when evolving in dynamic
environments. Both representation and dynamic
environments have been recognised as important open
issues in the field of genetic programming. This paper
outlines the need for further study on both topics in
the context of grammatical evolution, suggesting
further inspiration be taken from nature in an attempt
to improve the representations available to grammatical
evolution. The research undertaken to date is listed,
along with the future work to be completed.",
