Conversational Form-Generation: An Application of Interactive Genetic Algorithm to Architectural Design

The design process can be regarded as a recursive conversation between representation and interaction, where designers recursively "generate representations of their
interactions, and by interacting with representations simultaneously, designers generate relations with the representations of which they can then interact and repeat this process recursively." (Maturana and Varela, 1991)
This recursive conversation is quite typical and essential in the form-generation stage. This thesis shows how this recursive conversation can be boosted using Interactive
Genetic Algorithm(IGA). With the assistance of IGA, the form-generation software can support an interactive conversation between designers and computational
tools, by taking designers’ evaluation and modification into consideration during computation process. Based on this interactivity of IGA, this thesis proposes an alternative
working relationship between designers and computational tools, where they work in different scopes parallelly and share the outcome regularly. This alternative
relationship offers an opportunity where designers could maximize their creativity, and computational tools could apply their computation capability to optimize the
design idea. A form-generation platform is implemented grounded on the proposed working relationship, for form study in the early stage of design process.
