SAT solvers from the first competitions to Knuth's programs, each as a Docker image with a binary ready to run, the most thorough traceability we can offer (original sources, dated build environment, recipe and verification), and reproducible in a few clicks on your own machine.

A collective site, still being completed: please check, correct and contribute. Everything on these pages is generated from the data of the sat-heritage/docker-images repository as it stands today: which solvers build, which answer correctly, who wrote them, under which licence, with which awards. Much of it was assembled recently, year by year, partly with the help of an AI assistant, and is still being verified. Treat every claim as provisional and check it against the original competition material before relying on it. We strongly encourage pull requests and verification reports: a corrected author line, a licence, a working recipe, a missing solver, or the outcome of running an image on your own machine are all welcome as pull requests or issues. The goal is a site maintained by the SAT community as a whole. Images not on Docker Hub yet can be built locally with satex build <solver>:<year> (pip install satex).

Notes

The solver of the SAT 2002 competition, in its own release series. This release predates the competition output format, so a launcher turns its answer and its bare assignment lines into the s and v lines; the 2002 image prints them itself.

Licence

permissive You can use it, modify it and ship it in your own software, commercial or not, as long as you keep the copyright notices.

Read from Permission notice of the archive, a three-clause BSD licence, signed Armin Biere, Computer Systems Institute, ETH Zurich; this summary is informative, the licence text prevails. Corrections welcome by pull request.

Build it and run it

pip install satex && satex build limmat:biere
docker run --rm -v $PWD:/data satex/limmat:biere instance.cnf

This image is not on Docker Hub yet (checked 2026-11-13): the images are pushed in batches, and some entries cannot be built. Until then, satex build makes it on your machine from the archived sources and the recipe below, and the run command is the same. Mount the directory that holds your instance on /data; the proof file is optional and not produced by this solver. Its full provenance is kept: the archived sources, the pinned build environment and the recipe are all listed below, and satex build limmat:biere rebuilds the same image on your own machine if you would rather not trust ours (slower, same solver).

Download the sources limmat-1.3.tar.gz, the competition submission as archived by SAT Heritage, to build it yourself with the recipe below.
