ultrafilter posted:I don't know in what sense the PD is solvable and RPS isn't. Can you explain a bit more? Basically, in standard PD you can have an optimal strategy for raking in the most points. (Trust until you are betrayed, never trust again.) But you can't really define something like that in RPS, since between these three hands your decisions are inherently symmetrical. For example, one could use the strategy Always play rock. That sounds like a bad strategy, but statistically that person would still win 1/3 of his games. (1/2 if you don't count draws.) Especially since he might meet an opponent who has the similar tactic of "No choice but Scissors!" This is a bit of an oversimplification. But the point is that for every strategy which seems reasonably logical, there is one which is just as logical and would absolutely demolish it. The biggest difference is probably that the PD has the dual choice of being good vs evil, while in RPS you are mostly choosing from three different options where none of them is strictly better than the others. Also "winning" PD against only one opponent is trivial. Always betray. In the worst case it would be a draw. An "optimal" tit for tat player would actually lose against that. cant cook creole bream fucked around with this message at 23:01 on Feb 12, 2017 |

Well, now you just tipped it over to the other direction.

It's been incredibly fun guys! I've been eager to read the other two threads for a while now. And it's great to look into the minds of our opponents now.
