Self-segregation and enhanced cooperation in an evolving population through local information transmission

Effects of local information transmission and imitation among agents in an evolving population consisting of agents competing for limited resources are studied numerically through a model based on the evolutionary minority game (EMG). Enhanced cooperation is found to result from an effective self-segregation of the population into two groups with opposite characters. The self-segregation leads to an enhanced cooperation in that the winners per turn in the present model is higher than that in the minority game and EMG, and approaches the limiting value of (N−1)/2, where N is the number of agents in the population.
