With the evolution of highly sophisticated computational systems, the prospect of creating a collaborative system that integrates the strengths of humans and algorithmic processes in architecture is rising as a subject of high significance. This presentation explores the evolution of biologically inspired optimisation-oriented processes in design and introduces an interactive design method which relies on human designers interacting with the algorithmic processes to enable the capture of designers' intuition and creativity. It seeks to contribute to the current debate in the field of Interactive Genetic Algorithms and their capacity to accommodate objective and subjective design aims.
