The Lemonade Stand Game Competition: Solving Unsolvable Games

In December 2009 and November 2010, the first and second Lemonade Stand game competitions were held. In each competition, 9 teams competed, from University of Southampton, University College London, Yahoo!, Rutgers, Carnegie Mellon, Brown, Princeton, et cetera. The competition, in the spirit of Axelrod's iterated prisoner's dilemma competition, which addressed whether or not you should cooperate, asks the questions, "how should you cooperate, and with whom?" The third competition (whose results will be announced at IJCAI 2011) is open for submissions until July 1st, 2011.
