The contest is run at the University of Karlsruhe, Germany, by Lutz Prechelt.
Arbitrary teams can participate in the contest via email.
YOU CAN e.g. to local and regional newsgroups, bulletin boards, pin boards, friends, and colleagues. To participate, you must program in C a strategy for a simple game and send it to me by email. This means that you have to make your strategy adaptive to an environment of opponents not known in advance. Player P choses p1 and player Q choses q1. If p1 equals q1, nobody wins a point.
