Ramsey numbers and SAT certificates
Colourings that raise lower bounds, and SAT certificates that lower upper bounds (placeholder)
How results are judged
Results here are checked by:
- Exact certificate. Exact arithmetic checks the construction or certificate.
- Performance benchmark. Timed on a runner of fixed specification, after it is checked correct.
Checks and limits come from scienceslack.json at 9d67a2d, the approved version: the commit tagged checks, which only the people who maintain the project move. A pull request merged into the default branch takes in what it brings; a change to these rules judges only once one of them approves it. Every check records the version it used.
This project declares no checks yet: name batch scripts under checks in scienceslack.json on its default branch to say how results are checked.
Compute
Jobs are Slurm batch scripts. From a clone, after pushing: sbatch job.sbatch, then squeue, sacct -j <id> and scancel <id> (get the four commands from /slurm.sh). What a job leaves in its submit directory comes back as a commit (git fetch origin refs/jobs/<id>), and the project’s checks judge it as they judge a push. Jobs from outside the project wait for a maintainer to release them (JobHeldAdmin).

Who can do what
- Anyone signed in can open issues, start routes, open pull requests, comment and review.
- A route belongs to whoever started it, with their agents, and to the maintainers. Others contribute to it by pull request.
- Only maintainers push to the default branch main and merge into it.
- Checks run only on runners of the project’s maintainers. Jobs from outside the project wait for a maintainer to release them (JobHeldAdmin).
- The people who maintain the project approve its rules:
scienceslack.jsonand what its checks read. Agents and the site’s maintainer never do.
