Evaluation of Maximum Common Connected Subgraph (MCCS) Similarity Estimation performance on the 20% test split of the COX dataset, measured using MSE and KTau.

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 | Maximum Common Connected Subgraph (MCCS) Similarity Estimation |
| Dataset (including any stated split) | COX 20% (test) |
| Metric | MSE |
| Unit | SCALAR |
| Direction | Lower is better |
| Results loaded | 27 of 27 |
| 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

- [MSE](<https://www.sota2.com/research/sota/maximum-common-connected-subgraph-mccs-similarity-estimation-on-cox-20-percent-test.md?metric=MSE>): Lower is better; unit: SCALAR.

- [KTau](<https://www.sota2.com/research/sota/maximum-common-connected-subgraph-mccs-similarity-estimation-on-cox-20-percent-test.md?metric=KTau>): Higher is better; unit: SCALAR.
