Evolving building blocks for design using genetic engineering: A formal approach
J.S. Gero and F. Sudweeks (eds), Advances in Formal Design Methods for CAD , IFIP-University of Sydney, Sydney, pp. 29-48
This paper presents a formal approach to the evolution of a representation for use in a design process. The approach adopted is based on concepts associated with genetic engineering. An initial set of genes representing elementary building blocks is evolved into a set of complex genes representing targeted building blocks. These targeted building blocks have been evolved because they are more likely to produce designs which exhibit desired characteristics than the commencing elementary building blocks. The targeted building blocks can then be used in a design process. The paper presents a formal evolutionary model of design representations based on genetic algorithms and uses pattern recognition techniques to execute aspects of the genetic engineering. The paper describes how the state space of possible designs changes over time and illustrates the model with an example from the domain of two-dimensional layouts. It concludes with a discussion of style in design.
