Given that 2-bot is currently in seventh place, above the majority of clones and Chaos Army, EarlyBirdMimicBot's early success might be as much due to its willingness to fold in early rounds as to its more sophisticated tricks.

My being in the middle of the clone pack last round but above it this round may be because the GoofBots that CloneBot best exploits, 0-bot and 1-bot, are now dead or marginal.

I posted the full source code of MeasureBot in a comment here [LW(p) · GW(p)]:

I'm not sure how to link to comments. EDIT: I figured it out.

Needless to say, I am very happy that nobody chose to disqualify AbstractSpyTreeBot, although I was hoping that a few people would submit modified versions of it that had the same weakness.
