Games with a Weak Adversary
, 2014
"... We consider multiplayer graph games with partialobservation and parity objective. While the decision problem for threeplayer games with a coalition of the first and second players against the third player is undecidable in general, we present a decidability result for partialobservation games ..."

observation games where the first and third player are in a coalition against the second player, thus where the second player is adversarial but weaker due to partialobservation. We establish tight complexity bounds in the case where player 1 is less informed than player 2, namely 2EXPTIME
A Competitive Approach to Game Learning
"... Machine learning of game strategies has often depended on competitive methods that continually develop new strategies capable of defeating previous ones. We use a very inclusive definition of game and consider a framework within which a competitive algorithm makes repeated use of a strategy learnan ..."

learnang component that can learn strategies which defeat a given set of opponents. We describe game learning in terms of sets M and X of first and second player strategies, and connect the model with more familiar models of concept learning. We show the importance of the ideas of teaching set [9
Sequential estimation of dynamic discrete games
 Econometrica
"... This paper studies the estimation of dynamic discrete games of incomplete information. Two main econometric issues appear in the estimation of these models: the indeterminacy problem associated with the existence of multiple equilibria and the computational burden in the solution of the game. We ..."

, have some important limitations: they are seriously biased in small samples; they require consistent nonparametric estimators of players ’ choice probabilities in the first step, which are not always available; and they are asymptotically inefficient. Second, we show that a recursive extension
Structural results and explicit solution for twoplayer LQG systems on a finite time horizon
 In IEEE Conference on Decision and Control, pages 6542 – 6549
, 2013
"... It is wellknown that linear dynamical systems with Gaussian noise and quadratic cost (LQG) satisfy a separation principle. Finding the optimal controller amounts to solving separate dual problems; one for control and one for estimation. For the discretetime finitehorizon case, each problem is a ..."

paper has three main contributions. First, we prove a fundamental structural result: sufficient statistics for the controllers can be expressed as conditional means of the global state. Second, we give explicit statespace formulae for the optimal controller. These formulae are reminiscent
Mining Social Interaction Data in Virtual Worlds
"... Abstract. Virtual worlds and massively multiplayer online games are rich sources of information about largescale teams and groups, offering the tantalizing possibility of harvesting data about group formation, social networks, and network evolution. However these environments lack many of the cue ..."

To Mitigate or To Adapt: How to combat with Climate Change
, 2009
"... COMMENTS ARE WELCOME. The strategic interaction between mitigation and adaptation is analyzed with a noncooperative game, where regions are players, and where mitigation and adaptation are prefect substitutes in protecting against climate impacts. We allow for step by step decision making, where m ..."

mitigation is chosen first and adaptation second, and where the benefits of mitigation accrue only in the future. If marginal costs of adaptation negatively depend on global mitigation and if regions are relatively rich in terms of income, they simultaneously invest in both mitigation and adaptation
Asymptotically Good Ideal Linear Secret Sharing with Strong Multiplication over Any Finite Field
 Proceeding of 29th Annual IACR CRYPTO
, 2009
"... Abstract. This work deals with “MPCfriendly ” linear secret sharing schemes (LSSS), a mathematical primitive upon which secure multiparty computation (MPC) can be based and which was introduced by Cramer, Damgaard and Maurer (EUROCRYPT 2000). Chen and Cramer proposed a special class of such schem ..."

Second, we show that for every finite field Fq, there exists an infinite family of LSSS over Fq that is asymptotically good in the following sense: the schemes are “ideal, ” i.e., each share consists of a single Fqelement, and the schemes have tstrong multiplication on n players

"... The author develops a new gametheoretic approach, anchored not in Boolean twovalued logic but instead in linguistic fuzzy logic. The latter is characterized by two key features. First, the truth values of logical propositions span a set of linguistic terms such as true, very true, almost false, v ..."

, very false, and false. Second, the logic allows logical categories to overlap in contrast to Boolean logic, where the two possible logical categories, “true ” and “false, ” are sharply distinct. A game becomes a linguistic fuzzy logic game by turning strategies into linguistic fuzzy strategies
Putting Freeriding to Work: A Partnership Solution to the Commonproperty Problem
 Journal of Environmental Economics and Management
, 2009
"... Abstract The commonproperty problem results in excessive mining, hunting, and extraction of oil and water. The same phenomenon is also responsible for excessive investment in R&D and excessive outlays in rentseeking contests. We propose a “Partnership Solution ” to eliminate or at least mitig ..."
