Evolutionary developmental design (Evo-Devo-Design) is a design method that combines complex developmental techniques with an evolutionary optimisation techniques. In order to use such methods, the problem specific developmental and evaluation procedures typically need to be define using some kind of textual programming language. This paper reports on an alternative approach, in which designers can use Visual Dataflow Modelling (VDM) instead of textual programming. This research described how Evo-Devo-Design problems can defined using the VDM approach, and how they can subsequently be run using a Distributed Execution Environment (called Dexen) on multiple computers in parallel. A case study is presented, where the Evo-Devo-Design method is used to evolve designs for a house, optimised for daylight, energy consumption, and privacy.
