I suggest an everlasting battle of 1024 (or something) strategy bots. They die and survive at the more or less present tournament laws. Everybody has a right to come with a viable bot and throw it inside, let say once a day. Provided, that a bot with exactly the same code isn't already there. The upper limit for the code size is 1024 (or something) bytes. The current menagerie is visible here or somewhere else. Along with the most vital statistics.
