Abstract
In multiagent reinforcement learning, independent learners are those that do not observe the actions of other agents in the system. Due to the decentralization of information, it is challenging to design independent learners that drive play to equilibrium. This paper investigates the feasibility of using satisficing dynamics to guide independent learners to approximate equilibrium in stochastic games. For , an -satisficing policy update rule is any rule that instructs the agent to not change its policy when it is -best-responding to the policies of the remaining players; -satisficing paths are defined to be sequences of joint policies obtained when each agent uses some -satisficing policy update rule to select its next policy. We establish structural results on the existence of -satisficing paths into -equilibrium in both symmetric -player games and general stochastic games with two players. We then present an independent learning algorithm for -player symmetric games and give high probability guarantees of convergence to -equilibrium under self-play. This guarantee is made using symmetry alone, leveraging the previously unexploited structure of -satisficing paths.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
