The programs that produce SAT benchmarks, each as a Docker image: the families the competitions used, and others that live outside them, in papers and in solver tuning.

A pilot, and a collective one: please check, correct and contribute. Everything here is generated from the data of the sat-heritage/benchs-generators repository. A generator whose licence is unknown has its recipe published but no image, and a family with no generator is one we could not find or could not run: corrections, missing generators and licence clarifications are welcome as pull requests or issues. Adding your own generator takes four files, or just an issue with a link to your code: see adding a generator. The companion project for solvers is SAT Heritage.
