Affects of User Interaction Mechanisms in Multi-objective IGA

Brintrup, Alexandra and Hideyuki, Takagi (2007) Affects of User Interaction Mechanisms in Multi-objective IGA. In: Proceedings of Genetic and Evolutionary Computation Conference, University College London.


In this paper four mechanisms, fine and coarse grained fitness rating, linguistic evaluation and active user intervention are compared for use in the multi-objective IGA. The interaction mechanisms are tested on the ergonomic chair design problem. The active user intervention mechanism provided the best fitness convergence but resulted in the least diverse results. The fine grained evaluation provided a good blend of fitness convergence and diversity while the popular coarse grained discrete rating provided poor results. Linguistic evaluation resulted in poor qualitative fitness despite its fast speed of evaluation. The significant differences between interaction mechanisms show the need for further research.
