Max Kleiman-Weiner @maxkw.bsky.social · 22/07/2025In dyadic repeated interactions in the Game Generator, the Bayesian Reciprocator quickly learns to distinguish cooperators from cheaters, remains robust to errors, and achieves high population payoffs through sustained cooperation. 260
Max Kleiman-Weiner @maxkw.bsky.social · 22/07/2025Even in one-shot games with observability, the Bayesian Reciprocator learns from observing others' interactions and enables cooperation through indirect reciprocity 160
Max Kleiman-Weiner @maxkw.bsky.social · 22/07/2025Finally, when we tested it against memory-1 strategies (such as TFT and WSLS) in the iterated prisoner's dilemma, the Bayesian Reciprocator: expanded the range where cooperation is possible and dominated prior algorithms using the *same* model across simultaneous & sequential games. 160
