The evolutionary minority game consisting of a competing population with imitation possibility

We propose and study a modified version of the evolutionary minority game consisting of a competing population. Agents in the population are repeatedly competing to be in a minority and they have a common strategy. Each agent has a parameter p characterizing the probability with. which he is following the prediction of the common strategy. Agents are lined up in a one-dimensional chain with periodic boundary condition. Imitation is allowed among nearest neighboring agents. Numerical results show that the agents evolve into a state in which they self-segregate into opposite groups characterized by extreme behavior and imitation leads to considerable enhancement in the overall Performance of the population.
