Evaluation of Vehicle Routing Problem solvers on the training set of the OVRPL n=50 instances, reporting the objective value and solution gap.

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 | Vehicle Routing Problem |
| Dataset (including any stated split) | OVRPL n=50 (train) |
| Metric | Objective Value |
| Unit | SCALAR |
| Direction | Lower is better |
| Results loaded | 5 of 5 |
| 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

- [Objective Value](<https://www.sota2.com/research/sota/vehicle-routing-problem-on-ovrpl-n-50-train.md?metric=Objective%20Value>): Lower is better; unit: SCALAR.

- [Solution Gap](<https://www.sota2.com/research/sota/vehicle-routing-problem-on-ovrpl-n-50-train.md?metric=Solution%20Gap>): Lower is better; unit: PERCENT.
