This paper presents a comparative study of the original single swarm PSO with linear decreasing inertia weight and basic multi-swarm variant.The alternative population topology (multi-swarms) is a topic that is getting increased attention from the research community in recent years.We present evidence that it might be very beneficial to divide the population into two subswarms with partially restricted communication.The size of the sub-swarms is chosen with respect to a previously published study on this topic.The scaling of the methods is compared in three different dimensional settings.The results are statistically evaluated and discussed.The paper concludes with proposals for future research.
