“Tags [distinctive agent features observable by other agents] almost always define the network by delimiting the critical interactions, the major connections. Tags acquire this role because the adaptive processes that modify cas [complex adaptive systems] select for tags that mediate useful interactions and against tags that cause malfunctions. That is, agents with useful tags spread, while agents with malfunctioning tags cease to exist.” CommunicationEvolutionSystemsSocial BehaviorNetworksComplex Adaptive SystemsTags Book:Hidden order: how adaptation builds complexity Source: Hidden order: how adaptation builds complexity
