Making rotational invariance of particle swarm optimization based on correlativity
Wataru Kumagai, Keiichiro Yasuda · IEEJ Transactions on Electrical and Electronic Engineering · 2017
In this letter, we point out that particle swarm optimization (PSO) lacks rotational invariance through an analysis using numerical experiments. After the analysis based on rotational invariance, we develop PSO with rotational invariance based on correlativity. The performance of the proposed PSO with rotational invariance is verified through numerical experiments for typical separable benchmark functions without and with rotation.
