Evolving Concepts by On-line Inferiority Estimation and Elimination

This research is motivated by the need to rationalize the allocation of computational resources during a Pareto-based evolution of Set-based Concepts (SBCs). Such an evolution involves the simultaneous exploration of different design spaces, at both the conceptual and particular solution levels, with respect to multiple optimization objectives. Here, several techniques for an on-line estimation of the inferiority of conceptual solutions are suggested and investigated. Such techniques allow on-line intelligent elimination of inferior concepts, which aims at a reduction of the required computational resources.

To evaluate the effectiveness of the proposed techniques, unique concept-based measures and analysis methodology for evolving SBCs are suggested. Extensive statistical study is carried out to assess and compare the suggested techniques. Based on the statistical results, it is concluded that several of the proposed techniques are effective. It is also shown that the effectiveness varies in accordance with the difficulty level of the solved search problems. These conclusions are in accordance with the well-known optimization theorem of no-free lunch.
