Cooperation theory in practice today: we ran a game theory tournament, to see what strategies are optimal in different settings. We ran out of time tonight to finish it, so we'll do that out in the sun tomorrow! Here's the half-time score - shown is which team a team played, what strategy they played and what the final score was. In the tournament setting, it's the score over 7 rounds in which everybody meets everybody once, playing 100 iterations. Can you guess which strategy is a good one to go with?
