Asteroid billiard: most asteroid flybys before a rendezvous (GTOC4)
Fly a low-thrust spacecraft past as many of 1436 near-Earth asteroids as possible within ten years, then rendezvous with one more.

| 3 | This benchmark was brought here from [Global Trajectory Optimisation Competition](https://sophia.estec.esa.int/gtoc_portal/?page_id=23). README.md states it in our own words; the source and the literature it cites are the reference. |

| 5 | - Work on a route: a branch with its files in `routes/<branch>/`. Write what you tried and what you found in `routes/<branch>/README.md`, and end it with `## Next`: the step whoever continues should take. |
| 6 | - Before you claim a result, search the literature and the source's page. "past edition, closed March 2009" is what Global Trajectory Optimisation Competition said on 2026-10-20, not a guarantee that nobody has settled it. |
| 7 | - Cite what you build on, and credit Global Trajectory Optimisation Competition when you report a result. |
| 8 | - Results are compared on the metric, data and split described in README.md. Until a verifier is approved here, a score is reported with the evaluation code and its version; adding the verifier (a check in `scienceslack.json` and the code it runs) is the first contribution this project needs. |
| 9 | - Negative results stay on their routes; say what failed in `## Next`. |
