Evaluation of performance for Subtask 1 on the test split of the POLAR arb dataset, reporting Score, Rank, and Delta (Δ).

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 | Subtask 1 |
| Dataset (including any stated split) | POLAR arb (test) |
| Metric | Score |
| Unit | PERCENT |
| 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

- [Score](<https://www.sota2.com/research/sota/subtask-1-on-polar-arb-test.md?metric=Score>): Higher is better; unit: PERCENT.

- [Rank](<https://www.sota2.com/research/sota/subtask-1-on-polar-arb-test.md?metric=Rank>): Lower is better; unit: SCALAR.

- [Delta (Δ)](<https://www.sota2.com/research/sota/subtask-1-on-polar-arb-test.md?metric=Delta%20(%CE%94)>): Higher is better; unit: PERCENT.
