A modified evolutionary minority game with local imitation

In this work, we consider a network of agents who compete for limited resources through a modified evolutionary minority game model based on Kauffman network. The properties of such a system for different values of mean connectivity K of the network are studied. Simulation results suggest that the agents also tend to self-segregate into opposing groups characterized by extreme actions, and show that the agents can coordinate their behavior effectively in the system with K=2. Enhanced cooperation occurs also for a generalization of the model to multiple-choice evolutionary minority games in which the agents are allowed to choose among several options.
