 v4 * VonNeumannTopologyInitializer: Every particle is connected with the two following and the two previous particles, wrapping around at the beginning and the end of the population. [#References (Kennedy and Mendes, 2002)] investigated the impact of different topologies on algorithm performance. They found that the global PSO was quick to converge but yielded the worst results. Circular and weel topologies improved the results moderately and using the Von Neumann topology produed the best results.
