World-Wide-Mind

w2mind.computing.dcu.ie -> tyrrell's simulated environment -> scoreboard

This scoreboard lists the best performing minds, or action selection mechanisms. The minds are judged according to how often the animal mates. In the even of a tie, the minds are judged based on how long the animal was able to survive in the environment. Note that a creature that sleeps for its entire lifetime can actually survive quite long, but obviously has no chance of mating, and so cannot help the survival of the species.
