Detecting a Currency's Dominance or Dependence using Foreign Exchange Network Trees
Mark McDonald, Omer Suleman, Stacy Williams +2
In a system containing a large number of interacting stochastic processes, there will typically be many non-zero correlation coefficients. This makes it difficult to either visuali…
Evolution Management in a Complex Adaptive System: Engineering the Future
David M. D. Smith, Neil F. Johnson
We examine the feasibility of predicting and subsequently managing the future evolution of a Complex Adaptive System. Our archetypal system mimics a competitive population of mecha…
Effect of congestion costs on shortest paths through complex networks
Douglas J. Ashton, Timothy C. Jarrett, Neil F. Johnson
We analyze analytically the effect of congestion costs within a physically relevant, yet exactly solvable network model featuring central hubs. These costs lead to a competition be…
Plateaux formation, abrupt transitions, and fractional states in a competitive population with limited resources
H. Y. Chan, T. S. Lo, P. M. Hui +1
We study, both numerically and analytically, a Binary-Agent-Resource (B-A-R) model consisting of N agents who compete for a limited resource 1/2<L/N <1, where L is the maximum avai…
Error-driven Global Transition in a Competitive Population on a Network
Sehyo Charley Choe, Neil F. Johnson, Pak Ming Hui
We show, both analytically and numerically, that erroneous data transmission generates a global transition within a competitive population playing the Minority Game on a network. T…
Theory of Collective Dynamics in Multi-Agent Complex Systems
Neil F. Johnson, Sehyo C. Choe, Sean Gourley +2
We discuss a crowd-based theory for describing the collective behavior in Complex Systems comprising multi-agent populations competing for a limited resource. These systems -- whos…
