Examining grammars and grammatical evolution in dynamic environments

This paper is concerned with the effect of the grammar type on grammatical evolution when evolving in dynamic envi- ronments. 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 na- ture 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.
