Evaluation of Vertex Cover algorithms on Barabási–Albert random graphs generated with N=256 nodes and attachment parameter m=2. Performance is measured by solution quality metrics including Energy, Cover size, and Uncovered ratio.

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 | Vertex Cover |
| Dataset (including any stated split) | Barabási–Albert BA256 (m = 2) |
| Metric | Best Cover Size |
| Unit | SCALAR |
| Direction | Lower is better |
| Results loaded | 8 of 8 |
| 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

- [Best Cover Size](<https://www.sota2.com/research/sota/vertex-cover-on-barab-si-albert-ba256-m-2.md?metric=Best%20Cover%20Size>): Lower is better; unit: SCALAR.

- [Energy](<https://www.sota2.com/research/sota/vertex-cover-on-barab-si-albert-ba256-m-2.md?metric=Energy>): Lower is better; unit: SCALAR.

- [Cover Size](<https://www.sota2.com/research/sota/vertex-cover-on-barab-si-albert-ba256-m-2.md?metric=Cover%20Size>): Lower is better; unit: SCALAR.

- [Uncovered Ratio](<https://www.sota2.com/research/sota/vertex-cover-on-barab-si-albert-ba256-m-2.md?metric=Uncovered%20Ratio>): Lower is better; unit: PERCENT.
