Algorithmic game theory is a rather recent research field that lies at the intersection of economics, computer science and mathematics. Its origins in the early 1990's were largely motivated by the wealth of new applications that came into existence with the emergence of the Internet. The field pursues mathematical studies of games with a particular focus on computational and algorithmic issues. These studies are interdisciplinary in flavor and often demand for a combination of methodologies and techniques from the areas of optimization, algorithms and game theory. Algorithmic game theory contributed successfully to the understanding of many fundamental games in recent years and has become a highly active research field.

The two-day workshop will be hosted at the Center for Mathematics and Computer Science (CWI) in Amsterdam and will take place September 2-3, 2010. There will be four keynote talks and about 12 contributed talks.

Please register before August 16, 2010. For more information, see http://www.cwi.nl/~schaefer/agt10/

Positional games are a class in the wide spectrum of combinatorial games. Their main characteristic is a simple basic concept, but at the same time, in contrast to most of the other combinatorial games, a non-trivial theory supporting them. The scientific community working in positional games has witnessed a rapid expansion lately, and there are plenty of new topics in the area.

Abstract: The standard way of modelling imperfect information in games is in terms of information partitions for players. In this view, each player is associated with an equivalence relation over the set of game positions. For multi-player games of imperfect information defined in this manner it turns out that most of the interesting algorithmic questions like determining the winning strategy and synthesis of an equilibrium profile are undecidable. The crucial element which yields undecidability is the ability of the game model to implicitly encode arbitrary private communication between players. In this light, we propose a model where the players' information partitions are generated explicitly by means of communication. We define a notion of locally consistent equilibrium and suggest that this better captures the intuition of stable behaviour of players. We show that when communication is by means of public announcements, it is decidable to check whether locally consistent equilibrium profile exists.

This work is joint with R. Ramanujam (IMSc., Chennai).

The SIGDIAL venue provides a regular forum for the presentation of cutting edge research in discourse and dialogue to both academic and industry researchers. Continuing with a series of successful ten previous meetings, this conference spans the research interest area of discourse and dialogue. The conference is sponsored by the SIGDIAL organization, which serves as the Special Interest Group in discourse and dialogue for both ACL and ISCA. SIGDIAL 2010 will be co-located with Interspeech 2010 as a satellite event.

The Amsterdam Graduate Philosophy Conference 2010 is organised by the Department of Philosophy and the Institute for Logic, Language, and Computation of the Universiteit van Amsterdam. The 3rd Amsterdam Graduate Philosophy Conference is devoted to continue the discussions that were raised in the previous two conferences, as well as to lay the ground for new ones. The theme this year is Truth, Meaning, and Normativity.

We invite submissions from graduate researchers conducting novel philosophical research into any of the three conference topics. We also encourage submissions that inform the discussion about truth, meaning, and/or normativity by offering a philosophical interpretation of results from other fields such as logic, cognitive psychology and linguistics (including formal semantics and sociolinguistics).

Since the topics of truth, meaning, and normativity naturally feed into each other, we also welcome contributions whose particular aim is to explore any of the many intricate ways in which these notions relate to one another. Submissions on the role that these notions have played, or play, in the broad (analytic) tradition or, more specifically, within the linguistic turn are also of interest to the conference.
