An interactive approach for evolving pareto optimal architectural form

Architectural design is regarded as a challenging open ended activity aimed to transform an existing reality into a desired one. This transformation takes place via the generation of design alternatives. Digital morphogenesis techniques lend themselves to the task of producing design alternatives quicker and easily. In this paper, we introduce an interactive population-based model for evolving design alternatives. Our model enables designers to steer the trajectory of the evolutionary process. We use a population-based evolutionary approach that allows us to represent, evaluate and evolve design alternatives. We illustrate how the model is capable of generating a diverse space of alternatives, increasing the probability of finding unexpected designs. Finally we examine the results obtained, by defining measures of quality related to design intentions.
