Evaluation of model performance on the Game B matrix game environment, focusing on the estimation of joint payoffs and individual Q-values across different strategies.

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.

| Scope | Recorded value |
| --- | --- |
| Task | Matrix Game |
| Dataset (including any stated split) | Game B |
| Metric | Estimated Joint Payoff |
| Unit | SCALAR |
| Direction | Higher is better |
| Results loaded | 2 of 2 |
| Coverage | All results currently returned for this benchmark |

Evaluation settings may differ between results. The original papers and recorded configurations are needed to establish comparability. A shared metric name alone does not establish an identical protocol.

## Metrics

- [Estimated Joint Payoff](<https://www.sota2.com/research/sota/matrix-game-on-game-b.md?metric=Estimated%20Joint%20Payoff>): Higher is better; unit: SCALAR.

- [Estimated Individual Q-value](<https://www.sota2.com/research/sota/matrix-game-on-game-b.md?metric=Estimated%20Individual%20Q-value>): Higher is better; unit: SCALAR.

## Recorded results
