这是lecture note里面的介绍,但是是这章大后期了 POA (price of anarchy)就是在equilibrium情况下总cost和最小cost的比值。(这个东西很有意义 是因为在没有任何管理的情况下,并不是所有的情况都会发生,每个流量都会前往让自己cost最小的情况,而不是随机的,所以是合理的设定) 当前的例子,equilibrium 是上边走1/2...
POA等于这个game中的全局最优解 比 纳什均衡解中的最小值,也就是说,POA越大,意味着纳什均衡解中差的那一面越差。 POS等于这个game中的全局最优解 比 纳什均衡解中的最大值,POS越接近1,代表这个纳什均衡解好的那一面越好。 发布于 2018-11-23 22:54 AI 总结 如何理解博弈论中的POA(price of ana...
Most of us prefer to commute by the shortest route available, without taking into account the traffic congestion that we cause for others. Many networks, including computer networks, suffer from some type of this "selfish routing." In Selfish Routing and the Price of Anarchy, Tim Roughgarden st...

This solution concept is closely related to the well-studied price of anarchy. Furthermore, for a rich subclass of allocation problems, pure Nash equilibria are guaranteed to exist for our mechanisms. For many problems, the approximation factors we obtain at equilibrium improve upon the best known...

We are also able to quantify the asymptotic behaviour of the price of anarchy for this class of games. More precisely, we prove that if the parameters defining the constraints of each vehicle are drawn randomly from a given distribution, then, the value of the game converges almost surely to...
PoA = Price of Anarchy Anarchy = 无政府主义、混乱 如果不要中心化的authority来组织,那要付出多大的代价(相比性能下降多少)(我的理解)Notation game G = (N,S,u) 玩家有 N 个,单个某个玩家记为 i 单个某个玩家的策略集合为 S_i (这里只假定做的策略是确定性的,只选择某一个动作) 单个某个玩家...
