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).

Licence

weak copyleft Components under different licences: the strictest one rules the whole. You can use it in your own software, but changes to the solver itself must be published under the same licence.

Read from licence header of cryptominisat-ccnr/cms/src/msvc/stdint.h, cryptominisat-ccnr/breakid/src/bliss/utils.hh, cryptominisat-ccnr/breakid/src/Graph.cpp; this summary is informative, the licence text prevails. Corrections welcome by pull request.

Pull it from Docker and run it

docker pull satex/cryptominisat-ccnr:2020
docker run --rm -v $PWD:/data satex/cryptominisat-ccnr:2020 instance.cnf proof.out

No build needed: the image is published on Docker Hub (checked 2026-09-25). Mount the directory that holds your instance on /data; the proof file is optional. Its full provenance is kept: the archived sources, the pinned build environment and the recipe are all listed below, and satex build cryptominisat-ccnr:2020 rebuilds the same image on your own machine if you would rather not trust ours (slower, same solver).
