# CarButton1 on Safety Gymnasium Source: [CarButton1 on Safety Gymnasium]() Collection index: [llms.txt]() Data updated: 2026-04-30T07:42:41.060Z Evaluation of performance on the CarButton1 task within the Safety Gymnasium environment, measured by Reward and Cost. 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 | CarButton1 | | Dataset (including any stated split) | Safety Gymnasium | | Metric | Reward | | Unit | SCALAR | | Direction | Higher is better | | Results loaded | 19 of 19 | | 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 - [Reward](): Higher is better; unit: SCALAR. - [Cost](): Lower is better; unit: SCALAR. ## Recorded results | Method | Reward | Result date | Report paper | | --- | --- | --- | --- | | CPQ | 0.42 | Not recorded | 69f2e23455a3c32af89fc7ec | | CPQ | 0.42 | Not recorded | 69f2e23455a3c32af89fc7ec | | CDT + SAS | 0.27 | Not recorded | 69f2e23455a3c32af89fc7ec | | CDT + SAS | 0.27 | Not recorded | 69f2e23455a3c32af89fc7ec | | CDT | 0.21 | Not recorded | 69f2e23455a3c32af89fc7ec | | CDT | 0.21 | Not recorded | 69f2e23455a3c32af89fc7ec | | BEAR-Lag | 0.18 | Not recorded | 69f2e23455a3c32af89fc7ec | | BEAR-Lag | 0.18 | Not recorded | 69f2e23455a3c32af89fc7ec | | DT + SAS | 0.17 | Not recorded | 69f2e23455a3c32af89fc7ec | | DT + SAS | 0.17 | Not recorded | 69f2e23455a3c32af89fc7ec | | DCRL | 0.12 | Not recorded | 69f2e23455a3c32af89fc7ec | | BC-Safe | 0.07 | Not recorded | 69f2e23455a3c32af89fc7ec | | BC-Safe | 0.07 | Not recorded | 69f2e23455a3c32af89fc7ec | | BCQ-Lag | 0.04 | Not recorded | 69f2e23455a3c32af89fc7ec | | BCQ-Lag | 0.04 | Not recorded | 69f2e23455a3c32af89fc7ec | | BC-All | 0.03 | Not recorded | 69f2e23455a3c32af89fc7ec | | BC-All | 0.03 | Not recorded | 69f2e23455a3c32af89fc7ec | | COptiDICE | -0.08 | Not recorded | 69f2e23455a3c32af89fc7ec | | COptiDICE | -0.08 | Not recorded | 69f2e23455a3c32af89fc7ec | ### CPQ Reward: 0.42.
