On the Complexity of Pareto-optimal Nash and Strong Equilibria
We consider the computational complexity of coalitional solution concepts in scenarios related to load balancing such as anonymous and congestion games. In congestion games, Paret...

Congestion Games with Linearly Independent Paths: Convergence Time and Price of Anarchy
Abstract. 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 Anar...

A Unified Approach to Congestion Games and Two-Sided Markets
Abstract. Congestion games are a well-studied model for resource sharing among uncoordinated selfish agents. Usually, one assumes that the resources in a congestion game do not hav...

Weighted Congestion Games: Price of Anarchy, Universal Worst-Case Examples, and Tightness
We characterize the price of anarchy in weighted congestion games, as a function of the allowable resource cost functions. Our results provide as thorough an understanding of this ...

Congestion Games: Optimization in Competition
In a congestion game, several players simultaneously aim at allocating sets of resources, e.g., each player aims at allocating a shortest path between a source/destination pair in ...

Computing Approximate Nash Equilibria in Network Congestion Games
We consider the problem of computing -approximate Nash equilibria in network congestion games. The general problem is known to be PLS-complete for every > 0, but the reductions...

Taxes for Linear Atomic Congestion Games
We study congestion games where players aim to access a set of resources. Each player has a set of possible strategies and each resource has a function associating the latency it i...

Nash Dynamics in Constant Player and Bounded Jump Congestion Games
We study the convergence time of Nash dynamics in two classes of congestion games – constant player congestion games and bounded jump congestion games. It was shown by Ackermann ...

Congestion games with failures
We introduce a new class of games, congestion games with failures (CGFs), which extends the class of congestion games to allow for facility failures. In a basic CGF (BCGF) agents ...

Probabilistic Techniques in Algorithmic Game Theory
We consider applications of probabilistic techniques in the framework of algorithmic game theory. We focus on three distinct case studies: (i) The exploitation of the probabilistic...
