Swarm (1 of 2)

Loading video...

Caption: This video shows typical prey behavior when predators are not confused by multiple prey in their visual field. The prey spread out as much as possible while moving around randomly. Prey are randomly placed within the 512 x 512 arena. The swarm "phenotype" (the particular swarming behavior) does not depend on the initial condition, but the number of swarms that form, whether they will merge or separate, does depend on the initial placement of agents. For the purposes of visualization, 100 prey were cloned from a single genotype, as opposed to the 50 prey used in the fitness evaluation during the actual evolution experiment.
