# Communication Diversity in Particle Swarm Optimizers

@inproceedings{Oliveira2016CommunicationDI, title={Communication Diversity in Particle Swarm Optimizers}, author={Marcos A. C. Oliveira and Diego Pinheiro and Bruno Andrade and Carmelo Jos{\'e} Albanez Bastos Filho and Ronaldo Parente de Menezes}, booktitle={ANTS Conference}, year={2016} }

Since they were introduced, Particle Swarm Optimizers have suffered from early stagnation due to premature convergence. Assessing swarm spatial diversity might help to mitigate early stagnation but swarm spatial diversity itself emerges from the main property that essentially drives swarm optimizers towards convergence and distinctively distinguishes PSO from other optimization techniques: the social interaction between the particles. The swarm influence graph captures the structure of particle…
