## Useful for

- Solve a vehicle routing problem with capacity and time-window constraints
- Model and solve a linear programming task with Glop or PDLP solver
- Use CP-SAT to schedule jobs or assign tasks under constraints

## Why it’s here

- Star-counter measurements on 2026-11-04 (UTC), 00:25–01:54: 14323 → 14323 stars (+0). This is the change over that interval.
- Estimated end-of-day forecast: about +3 stars, using observed gains and the previous day.
- Recent forks include notable developers: @elmaestrotic (269 followers).

## Star trust

Star growth looks organic.

Star-trust labels are heuristics based on the repository’s behavior, not a check of every stargazer.

## Numbers

- Forks: 2,542
- Issues and pull requests: 4,375
- Watchers: 311
- Average over the last week: 4 per day
- Usual pace: 7 per day
- Stars in the last hour (measured): 0
- Latest release: v9.15 (2026-01-12)

Magnitude (0–10) measures how fast and how unusually interest in a repository is growing right now. It is not a quality score.
Days are UTC. “So far today” is a fact; “expected by the end of the day” is a forecast.
Summaries and use cases are written by an LLM (DeepSeek V4.1 Flash) from the README and may be inaccurate: verify specific claims (benchmarks, speed, hardware) in the repository itself.
Data as of 2026-11-04 01:58 UTC, updated every 30 minutes.
