Evaluation of agent performance on the standard 4x4 FrozenLake environment, specifically measuring critical state safety rate, trajectory-level safety, and total reward.

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 | Source Task Performance |
| Dataset (including any stated split) | Frozen Lake standard\_4x4 |
| Metric | Critical State Safety Rate |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 4 of 4 |
| 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

- [Critical State Safety Rate](<https://www.sota2.com/research/sota/source-task-performance-on-frozen-lake-standard_4x4.md?metric=Critical%20State%20Safety%20Rate>): Higher is better; unit: PERCENT.

- [Trajectory-Level Safety](<https://www.sota2.com/research/sota/source-task-performance-on-frozen-lake-standard_4x4.md?metric=Trajectory-Level%20Safety>): Higher is better; unit: PERCENT.

- [Total Reward](<https://www.sota2.com/research/sota/source-task-performance-on-frozen-lake-standard_4x4.md?metric=Total%20Reward>): Higher is better; unit: PERCENT.
