I find it somewhat amusing that SimHatingTitForTat has an average score second only to CheeseBot, and is one of the constant first-round survivalists... but just doesn't quite make it into the finals. Not bad for an algorithm that was an attempt to translate Tit-for-Tat's simplicity and reflectiveness into this particular tournament's terms. If the terms of the tourney were somewhat different, focusing more on 'avoiding total loss' rather than 'maximized score each game', then, well... :)
(I would be quite happy to see any further tournaments get run - I might even manage to come up with further ideas for the same.)
I'm kinda surprised, my naive intuition was that SimHatingTitForTat would force a cooperative win.
Does anyone know if the lack of SimHatingTitForTat getting into the finals is an artifact of the algorithms knowing the length of the rounds? (I.e. they can decide to backstab on the final turn to get an extra point).
