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 …

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 …

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 …

The price of anarchy in series-parallel network congestion games

B Hao, C Michini - Mathematical Programming, 2024 - Springer
We study the inefficiency of pure Nash equilibria in symmetric network congestion games
defined over series-parallel networks with affine edge delays. For arbitrary networks, Correa …

Contention issues in congestion games

E Koutsoupias, K Papakonstantinopoulou - … 2012, Warwick, UK, July 9-13 …, 2012 - Springer
We study time-dependent strategies for playing congestion games. The players can time
their participation in the game with the hope that fewer players will compete for the same …

Uniform mixed equilibria in network congestion games with link failures

V Bilò, L Moscardelli, C Vinci - 45th International Colloquium on …, 2018 - drops.dagstuhl.de
Motivated by possible applications in fault-tolerant routing, we introduce the notion of
uniform mixed equilibria in network congestion games with adversarial link failures, where …

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 …

Routing (un-) splittable flow in games with player-specific affine latency functions

M Gairing, B Monien, K Tiemann - ACM Transactions on Algorithms …, 2011 - dl.acm.org
In this work we study weighted network congestion games with player-specific latency
functions where selfish players wish to route their traffic through a shared network. We …

Symmetry in network congestion games: Pure equilibria and anarchy cost

D Fotakis, S Kontogiannis, P Spirakis - International Workshop on …, 2005 - Springer
We study computational and coordination efficiency issues of Nash equilibria in symmetric
network congestion games. We first propose a simple and natural greedy method that …

Inefficiency of pure nash equilibria in series-parallel network congestion games

B Hao, C Michini - International Conference on Web and Internet …, 2022 - Springer
We study the inefficiency of pure Nash equilibria in symmetric unweighted network
congestion games defined over series-parallel networks. We introduce a quantity y (D) to …
