移动Agent间协作的演化

Evolution of Cooperation among Mobile Agents

摘要:

我们研究了移动球员之间的合作,模仿生物群体的集体运动,并在规定的半径$R$内与邻居互动的演化的影响。采用囚徒困境的游戏和雪堆游戏的比喻,我们发现,合作可以保持,甚至提高低速度和小的回报参数,当与所有代理不动的情况下相比。但是这种协作的增强在很大程度上取决于$R$的值,并且对于适当的$R$值,存在最佳速度值以引起最大协作水平。此外,我们还发现,当速度一定时,$R$的中间值或初始种群密度最有利于合作。根据支付参数,系统可以达到一个吸收的合作状态时,雪堆游戏。我们的发现可能有助于理解社会系统中个体流动性与合作行为之间的关系。

英文摘要:

We study the effects of mobility on the evolution of cooperation among mobile players, which imitate collective motion of biological flocks and interact with neighbors within a prescribed radius $R$. Adopting the prisoner's dilemma game and the snowdrift game as metaphors, we find that cooperation can be maintained and even enhanced for low velocities and small payoff parameters, when compared with the case that all agents do not move. But such enhancement of cooperation is largely determined by the value of $R$, and for modest values of $R$, there is an optimal value of velocity to induce the maximum cooperation level. Besides, we find that intermediate values of $R$ or initial population densities are most favorable for cooperation, when the velocity is fixed. Depending on the payoff parameters, the system can reach an absorbing state of cooperation when the snowdrift game is played. Our findings may help understanding the relations between individual mobility and cooperative behavior in social systems.
