Evaluation of models learning Partial Differential Equations (PDEs) on the specific Helmholtz 2D configuration (a=20), measured by Relative L2 error.

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 | Learning PDEs |
| Dataset (including any stated split) | Helmholtz 2D a=20 |
| Metric | Relative L2 Error |
| Unit | PERCENT |
| Direction | Lower is better |
| Results loaded | 7 of 7 |
| 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

- [Relative L2 Error](<https://www.sota2.com/research/sota/learning-pdes-on-helmholtz-2d-a-20.md?metric=Relative%20L2%20Error>): Lower is better; unit: PERCENT.
