Maybe? Does tit-for-tat have the utility-wasting “defect on the last move” injunction?
Not by default. From what I’ve seen, though, few PD tourneys are arranged in such a way that the competing programs can know which move is the last, so there’s less evidence available.
I just compared “always cooperate with other TDT users; for everyone else, tit-for-tat” to ‘tit-for-tat’ in the case that’s what TDT says.
