基于FIFO策略的时间路由博弈

Routing Games over Time with FIFO policy

Anisse Ismaili

摘要:

我们研究原子路由游戏,每个代理人都沿着它决定的边缘和通过时间旅行。到达边缘的代理首先在\emph{first-in-first-out}队列中排队,并且可以等待:边缘与容量相关联,该容量定义了每个时间步长有多少代理可以从队列的头部弹出并进入边缘,以在固定延迟内进行传输。我们表明,最佳响应优化问题是不可近似的,并决定存在一个纳什均衡是完整的第二层次的多项式。然后,我们放弃了合理性假设,引入了基于GPS导航的行为概念,并研究了其最坏情况下的效率比协调。

英文摘要:

We study atomic routing games where every agent travels both along its decided edges and through time. The agents arriving on an edge are first lined up in a \emph{first-in-first-out} queue and may wait: an edge is associated with a capacity, which defines how many agents-per-time-step can pop from the queue's head and enter the edge, to transit for a fixed delay. We show that the best-response optimization problem is not approximable, and that deciding the existence of a Nash equilibrium is complete for the second level of the polynomial hierarchy. Then, we drop the rationality assumption, introduce a behavioral concept based on GPS navigation, and study its worst-case efficiency ratio to coordination.
