Realistic network growth using only local information: From random to scale-free and beyond
David M. D. Smith, Chiu Fan Lee, Neil F. Johnson
We introduce a simple one-parameter network growth algorithm which is able to reproduce a wide variety of realistic network structures but without having to invoke any global infor…
Predictability, Risk and Online Management in a Complex System of Adaptive Agents
David M. D. Smith, Neil F. Johnson
We discuss the feasibility of predicting, managing and subsequently manipulating, the future evolution of a Complex Adaptive System. Our archetypal system mimics a population of ad…
Interplay between function and structure in complex networks
Timothy C. Jarrett, Douglas J. Ashton, Mark Fricker +1
We show that abrupt structural transitions can arise in functionally optimal networks, driven by small changes in the level of transport congestion. Our results offer an explanatio…
Effects of decision-making on the transport costs across complex networks
Sean Gourley, Neil F. Johnson
We analyze the effects of agents' decisions on the creation of congestion on a centralized network with ring-and-hub topology. We show that there are two classes of agents each dis…
Pair Formation within Multi-Agent Populations
David M. D. Smith, Neil F. Johnson
We present a simple model for the formation of pairs in multi-agent populations of type A and B which move freely on a spatial network. Each agent of population A (and B) is labele…
Multi-Agent Complex Systems and Many-Body Physics
Neil F. Johnson, David M. D. Smith, Pak Ming Hui
Multi-agent complex systems comprising populations of decision-making particles, have many potential applications across the biological, informational and social sciences. We show…
