关于拟平稳平均场对策模型

On quasi-stationary Mean Field Games models

Charafeddine Mouzouni

摘要:

我们探讨了近视球员在平均场比赛中的决策机制。在每一个瞬间,代理人设定一个策略,通过假设他们的环境是不变的来优化他们的预期未来成本。随着系统的发展,玩家观察系统的发展,并在没有预料的情况下适应新的环境。在特定的费用结构下,这些模型产生了准平稳性质的偏微分方程的耦合系统。我们给出了这类系统存在唯一经典解的充分条件,并从N-局中人随机微分对策模型出发,给出了这类系统的严格推导.最后,我们证明了人口可以自组织和指数快速收敛到遍历平均场博弈均衡,如果初始分布是足够接近它和哈密尔顿是二次的。

英文摘要:

We explore a mechanism of decision-making in Mean Field Games with myopic players. At each instant, agents set a strategy which optimizes their expected future cost by assuming their environment as immutable. As the system evolves, the players observe the evolution of the system and adapt to their new environment without anticipating. With a specific cost structures, these models give rise to coupled systems of partial differential equations of quasi-stationary nature. We provide sufficient conditions for the existence and uniqueness of classical solutions for these systems, and give a rigorous derivation of these systems from N-players stochastic differential games models. Finally, we show that the population can self-organize and converge exponentially fast to the ergodic Mean Field Games equilibrium, if the initial distribution is sufficiently close to it and the Hamiltonian is quadratic.
