Abstract:

The evolutionary minority game by imitating neighbor's p value is investigated. We allow the agent to modify her p value after imitation. Numerical results show that there exists an optimal level of correlation between the agent's new p value and her neighbor's p value after imitation, at which the agents evolve into a state in which they self-segregate into nearly equal-sized opposing groups characterized by extreme behavior.The evolution by imitation can considerably enhances the system's coordination.

Key words: minority game, imitation, evolution
