The recent introduction of inexpensive eyetrackers has opened up a wealth of opportunities for researchers to study attention in interactive tasks. No software package has previously been available to help researchers exploit those opportunities. We created "the pyeTribe," a software package that offers, among others, the following features: first, a communication platform between many eyetrack...

A game of incomplete information or a Bayesian game is a game in which players do not have full information about each others payoffs. In a strategic situation where a player’s payoff depends on what actions his rivals will take, this poses a problem because a player does not know which game is being played. There are several reasons why players may not have full information about each others’p...

We present a simple primal-dual algorithm for computing approximate Nash equilibria in two-person zero-sum sequential games with incomplete information and perfect recall (like Texas Hold’em poker). Our algorithm only performs basic iterations (i.e matvec multiplications, clipping, etc., and no calls to external first-order oracles, no matrix inversions, etc.) and is applicable to a broad class...

A key challenge in solving extensive-form games is dealing with large, or even infinite, action spaces. In games of imperfect information, the leading approach is to find a Nash equilibrium in a smaller abstract version of the game that includes only a few actions at each decision point, and then map the solution back to the original game. However, it is difficult to know which actions should b...

many appealing multicast services such as on-demand tv, teleconference, online games and etc. can benefit from high available bandwidth in multi-radio multi-channel wireless mesh networks. when multiple simultaneous transmissions use a similar channel to transmit data packets, network performance degrades to a large extant. designing a good multicast tree to route data packets could enhance the...

game theory models decision makers' behaviors in strategic situations. since the structures of games are different, behavior and preferences of the players are different in various types of game. this paper reviews various situations of games. here, characteristics of some common games are discussed and compared. specifically, we focus on a group of games called symmetric games including p...

The theory of large one-shot simultaneous-play games with a biosocial typology has been presented in both the individualized and distributionalized forms— large individualized games (LIG) and large distributionalized games (LDG), respectively. Using an example of an LDG with two actions and a single trait in which some Nash equilibrium distributions cannot be induced by the Nash equilibria of t...

Sometimes, in dynamic games, it is useful to reason not only about the existence of strategies for players, but also about what these strategies are, and how players select and construct them. We study dynamic games with simultaneous moves, repeated normal form games and show that this reasoning can be carried out by considering a single game, and studying composition of “local” strategies. We ...
