Intrinsic robustness of the price of anarchy
T Roughgarden - Journal of the ACM (JACM), 2015 - dl.acm.org
The price of anarchy, defined as the ratio of the worst-case objective function value of a
Nash equilibrium of a game and that of an optimal outcome, quantifies the inefficiency of …

The price of anarchy in games of incomplete information
T Roughgarden - Proceedings of the 13th ACM Conference on Electronic …, 2012 - dl.acm.org
We define smooth games of incomplete information. We prove an" extension theorem" for
such games: price of anarchy bounds for pure Nash equilibria for all induced full-information …

Bounding the inefficiency of outcomes in generalized second price auctions
Abstract The Generalized Second Price (GSP) auction is the primary auction used for
monetizing the use of the Internet. It is well-known that truthtelling is not a dominant strategy …

Utility design for distributed resource allocation—part i: Characterizing and optimizing the exact price of anarchy
D Paccagnan, R Chandan… - IEEE Transactions on …, 2019 - ieeexplore.ieee.org
Game theory has emerged as a fruitful paradigm for the design of networked multiagent
systems. A fundamental component of this approach is the design of agents' utility functions …

Altruism and its impact on the price of anarchy
We study the inefficiency of equilibria for congestion games when players are (partially)
altruistic. We model altruistic behavior by assuming that player i's perceived cost is a convex …
