Uncovering communication density in PSO using complex network

Abstract

In this study, we investigate the communication in particle swarm optimization (PSO) by the means of network visualization. We measure the communication density of PSO optimizing four different benchmark functions. It is presented that the communication density varies over different fitness landscapes and in different phases of the optimizing process. We analyze the results in terms of use for future research. © ECMS Zita Zoltay Paprika, Péter Horák, Kata Váradi,Péter Tamás Zwierczyk, Ágnes Vidovics-Dancs, János Péter Rádics (Editors).
