We consider the problem of computing additively approximate Nash equilibria in noncooperative two-player games. We provide a new polynomial time algorithm that achieves an approximation guarantee of 0.36392. We first provide a simpler algorithm, that achie ...
The advances in automatic facial expression recognition make it possible to mine and characterize large amounts of data, opening a wide research domain on behavioral understanding. In this paper, we leverage the use of a state-of-theart facial expression r ...
This paper presents a game-theoretic model for the international negotiations that should take place to renew or extend the Kyoto protocol beyond 2012. These negotiations should lead to a self-enforcing agreement on a burden sharing scheme to realize the n ...
The increasing adoption of smartphones and tablets has provided tens of millions of users with substantial resources for computation, communication and sensing. The availability of these resources has a huge potential to positively transform our society an ...
We summarize classical and recent results about two-player games played on graphs with omega-regular objectives. These games have applications in the verification and synthesis of reactive systems. Important distinctions are whether a graph game is turn-ba ...

We present a human computation game based on the popular board game - Dixit. We ask the players not only for annotations, but for a direct critique of the result of an automated system.We present the results of the initial run of the game, in which the ans ...
In games, the goals and interests of players are key factors in their behavior. However, techniques used by networked games to cope with infrequent updates and message loss, such as dead reckoning, estimate a player's movements based mainly on previous obs ...

Smartphones are an ideal platform for local multiplayer games, thanks to their computational and networking ca- pabilities as well as their popularity and portability. How- ever, existing game engines do not exploit the locality of players to improve game ...
