The price of anarchy (POA) is a worst-case measure of the inefficiency of selfish behavior, defined as the ratio of the objective function value of a worst Nash equilibrium of a g...
Cut games and party affiliation games are well-known classes of potential games. Schaffer and Yannakakis showed that computing pure Nash equilibrium in these games is PLScomplete....
We study network load games, a class of routing games in networks which generalize selfish routing games on networks consisting of parallel links. In these games, each user aims t...

Games may be represented in many different ways, and different representations of games affect the complexity of problems associated with games, such as finding a Nash equilib...
We analyse the computational complexity of finding Nash equilibria in stochastic multiplayer games with ω-regular objectives.While the existence of an equilibrium whose payoff fal...
