Local Neighborhood Implementa0on •  For the basic PSO, neighborhood is organized based on par0cle indices (not distance). –  Cheap –  neighborhood overlap –  guarantees convergence under the given constraints . –  There is no need for velocity clamping vmax. € Social Network Structures •  The social structure for PSO determines the forma0on of overlapping neighborhoods, where par0cles within a neighborhood influence one another. •  The flow of informa0on through a social network, depends on: –  the degree of connec0vity among nodes –  The amount of clustering –  The average shortest distance from one node to another. Impacts •  Connec0vity –  Highly connected: fast informa0on flow, quick popula0on...
