Do you know of any active AI programming contests?

Over the summer, I competed in this programming contest to design an AI to play a complicated version of rock-paper-scissors. My bot ended up in about the top 25%, but there were enough other entrants that I didn’t make it past the first round. It was fun, and I am looking for another contest that I might be able to enter.

A Google search for this returns a ton of past contests, many of which sound fun (like a battleship-playing AI), but ended a while ago. Most active contests that show up are way too advanced for me, such as passing the Turing test. I am looking for something where the basic strategy is simple, but there is a lot of room for improvement. Since Google failed me, I am turning to the help of the collective.
