Using Clustering Techniques to Improve the Performance of a Multi-objective Particle Swarm Optimizer
13 years 10 months ago
In this paper, we present an extension of the heuristic called “particle swarm optimization” (PSO) that is able to deal with multiobjective optimization problems. Our approach ...
