The 2nd German Day on Computational Game Theory will take place on Wednesday, February 11th, 2015, at the Department of Mathematics, TU Berlin. The event will be preceded by a reception and an open problems session in the afternoon of Tuesday 10th. We want to bring together researchers who are interested in algorithmic or computational aspects of game theory, social choice, and related areas. The aim of this one-and-half-day-event is to provide an opportunity to foster collaboration, present research and exchange ideas at an informal and relaxed level. This website will be updated with further informations as soon as they are available.
