Reevaluating human colonization of the Caribbean using chronometric hygiene and Bayesian modeling.

abstract：:Animals, humans, and multi-robot systems operate in dynamic environments, where the ability to respond to changing circumstances is paramount. An effective collective response requires suitable information transfer among agents and thus critically depends on the interaction network. To investigate the influence of the...
