Evaluation of policy performance for a 2x2 Queueing Network configuration where arrival rates result in utilization (rho) of (0.90, 0.90). Performance is measured by Value, Standard Error, and Gap percentage.

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 | Policy Evaluation |
| Dataset (including any stated split) | 2x2 Queueing Network rho = (0.90, 0.90) |
| Metric | Value |
| Unit | SCALAR |
| Direction | Higher is better |
| Results loaded | 6 of 6 |
| 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

- [Value](<https://www.sota2.com/research/sota/policy-evaluation-on-2x2-queueing-network-rho-0-90-0-90.md?metric=Value>): Higher is better; unit: SCALAR.

- [Standard Error](<https://www.sota2.com/research/sota/policy-evaluation-on-2x2-queueing-network-rho-0-90-0-90.md?metric=Standard%20Error>): Lower is better; unit: SCALAR.

- [Gap (%)](<https://www.sota2.com/research/sota/policy-evaluation-on-2x2-queueing-network-rho-0-90-0-90.md?metric=Gap%20(%25)>): Lower is better; unit: PERCENT.
