Licence
weak copyleft You can use it in your own software, but changes to the solver itself must be published under the same licence.
- GNU Lesser General Public License 2.1 LGPL-2.1 · weak copyleft
The solver's code stays LGPL when modified and redistributed, but a program that only links to it can keep its own licence. Full text
Read from licence file Riss7.1/riss7/LICENSE; this summary is informative, the licence text prevails. Corrections welcome by pull request.
Pull it from Docker and run it
docker pull satex/riss7.1:2019 docker run --rm -v $PWD:/data satex/riss7.1:2019 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 riss7.1:2019 rebuilds the same image on your own machine if you would rather not trust ours (slower, same solver).
Download the sources Riss7.1.zip, the competition submission as archived by SAT Heritage, to build it yourself with the recipe below. The Zenodo record holding the archives of this year was downloaded 2 973 times (Zenodo counts per record, not per file).
