Evolving a logo design using Lindenmayer systems, Postscript & Grammatical Evolution

We present an application of grammatical evolution to the exploration of Lindenmayer systems. The resulting L-systems are expressed in the postscript language, and as such a postscript grammar was provided as input to the grammatical evolution algorithm. The system takes the form of an interactive evolutionary algorithm, with a human-in-the-loop acting as the fitness function for the generated L-systems. The motivation for this research was to evolve a logo for the UCD Natural Computing Research & Applications group, and to this end the study was a success.
