Decision Making, Strategy dynamics, and Crowd Formation in Agent-based models of Competing Populations
K. P. Chan, Pak Ming Hui, Neil F. Johnson
The Minority Game (MG) is a basic multi-agent model representing a simplified and binary form of the bar attendance model of Arthur. The model has an informationally efficient phas…
Transitions in collective response in multi-agent models of competing populations driven by resource level
Sonic H. Y. Chan, T. S. Lo, P. M. Hui +1
We aim to study the effects of controlling the resource level in agent-based models. We study, both numerical and analytically, a Binary-Agent-Resource (B-A-R) model in which a…
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…
Effects of aging and links removal on epidemic dynamics in scale-free networks
K. P. Chan, Dafang Zheng, P. M. Hui
We study the combined effects of aging and links removal on epidemic dynamics in the Barabási-Albert scale-free networks. The epidemic is described by a susceptible-infected-refrac…
Dynamical interplay between local connectivity and global competition in a networked population
S. Gourley, S. C. Choe, P. M. Hui +1
We show, both numerically and analytically, that the consequences of 'wiring up' a competitive population depend quite dramatically on the interplay between the local connectivity…
Dimensional Crossover in the Effective Second Harmonic Generation of Films of Random Dielectrics
P. M. Hui, C. Xu, D. Stroud
The effective nonlinear response of films of random composites consisting of a binary composite with nonlinear particles randomly embedded in a linear host is theoretically and num…
Second Harmonic Generation for a Dilute Suspension of Coated Particles
P. M. Hui, C. Xu, D. Stroud
We derive an expression for the effective second-harmonic coefficient of a dilute suspension of coated spherical particles. It is assumed that the coating material, but not the cor…
Epidemics and Dimensionality in Hierarchical Networks
Dafang Zheng, P. M. Hui, Steffen Trimper +1
Epidemiological processes are studied within a recently proposed hierarchical network model using the susceptible-infected-refractory dynamics of an epidemic. Within the network mo…
Crowd-Anticrowd Theory of Collective Dynamics in Competitive, Multi-Agent Populations and Networks
Neil F. Johnson, Pak Ming Hui
We discuss a crowd-based theory for describing the collective behavior in a generic multi-agent population which is competing for a limited resource. These systems -- whose binary…
Non-universal scaling in a model of information transmission and herd behavior
Dafang Zheng, P. M. Hui, N. F. Johnson
We present a generalized dynamical model describing the sharing of information, and corresponding herd behavior, in a population based on the recent model proposed by Eguiluz and Z…
