摘要

The purpose of this paper is to investigate generative and evolutionary design models by the new idea of co-evolution. Multi-objective optimization is our main concern. A dynamic co-evolution model is presented with detailed description of its application in eco-conscious housing design. Area and solar constraints of housing design problems are considered with maximum architectural area and solar illumination been optimized. We use dynamic niche models based on a fitness-sharing scheme to define energy and fitness functions for the co-evolution system. Early experimental data are presented and analyzed to show the effectiveness of this approach to evolutionary design optimization and its computational implementation of the algorithms.

摘要

The traditional particle swarm optimization technique is incorporated with multi-agent systems. A new PSO framework HMAS is presented with particles as agents. Actions and properties of agents are defined. We also present a test application in cluster analysis which extends the powerful algorithm CLARA and CLARANS. Implementation is given with experiment data. The results show that the new HMAS has better performance in searching the sample space than the non-agent systems.

摘要

This paper deals with periodic solutions of impulsive second order boundary value problems with parameter, Existence results are presented for nonlinearity with mixed sublinear and superlinear term at λ-0 and (or) λ≠0. Continua of the solution set are obtained. The main technique is fixed point argument of expansion and compression type.
