摘要：

A variant of the evolutionary minority game is Proposed. Agents' strategies given by probabilities p can be changed by imitation. Numerical results show that the agents evolve into a state in which they self-segregate into opposite groups characterized by extreme behaviours. The evolution by imitation can considerably enhance the system's coordination.
