Congestion games with linearly independent paths: Convergence time and price of anarchy

D Fotakis - Theory of Computing Systems, 2010 - Springer
We investigate the effect of linear independence in the strategies of congestion games on
the convergence time of best improvement sequences and on the pure Price of Anarchy. In …

Path deviations outperform approximate stability in heterogeneous congestion games

P Kleer, G Schäfer - … Game Theory: 10th International Symposium, SAGT …, 2017 - Springer
We consider non-atomic network congestion games with heterogeneous players where the
latencies of the paths are subject to some bounded deviations. This model encompasses …

Inefficiency of pure Nash equilibria in network congestion games: the impact of symmetry and network structure

B Hao, C Michini - ACM Transactions on Economics and Computation, 2024 - dl.acm.org
We study the inefficiency of pure Nash equilibria in symmetric unweighted network
congestion games. We first explore the impact of symmetry on the worst-case PoA of …

Optimal price of anarchy of polynomial and super-polynomial bottleneck congestion games

R Kannan, C Busch, AV Vasilakos - International Conference on Game …, 2011 - Springer
We introduce (super) polynomial bottleneck games, where the utility costs of the players are
(super) polynomial functions of the congestion of the resources that they use, and the social …

[PDF][PDF] The impact of collusion on the price of anarchy in nonatomic and discrete network games

T Harks - Preprint, 2008 - optimization-online.org
Hayrapetyan, Tardos and Wexler recently introduced a framework to study the impact of
collusion in congestion games on the quality of Nash equilibria. We adopt their framework to …

Congestion games with linearly independent paths: Convergence time and price of anarchy

D Fotakis - International Symposium on Algorithmic Game Theory, 2008 - Springer
We investigate the effect of linear independence in the strategies of congestion games on
the convergence time of best response dynamics and on the pure Price of Anarchy. In …

Complexity of pure Nash equilibria in player-specific network congestion games

H Ackermann, A Skopalik - Internet Mathematics, 2008 - Taylor & Francis
Network congestion games with player-specific delay functions do not possess pure Nash
equilibria in general. We therefore address the computational complexity of the …

The inefficiency of Nash and subgame perfect equilibria for network routing

J Correa, J de Jong, B De Keijzer… - … of operations research, 2019 - pubsonline.informs.org
This paper provides new bounds on the quality of equilibria in finite congestion games with
affine cost functions, specifically for atomic network routing games. It is well known that the …
