Abstract

We follow up on the work of Ebner[1] in studying representationsfor evolutionary design of objects. We adopt both the methodand the simulation framework, and perform more thorough experiments.We design new representations, both direct and indirect, and comparetheir performance to the original work. We design and make use of a specialisedsystem for distributed computing that integrates smoothly withthe EO library[5]. First, we confirm the results of Ebner with VRMLscene graphs representation. Next, we demonstrate how both of the newrepresentations based on triangular mesh perform significantly better.Finally, we study and improve the performance of the distributed systemthat we utilised to run our experiments on tens of computing nodes.
