bliss - compute graph automorphisms - by Tommi Junttila, Petteri Kaski - with patches from Debian and for SageMath. Archived because upstream has become active again in 2021.
When filing to ship the SCIP solver on Conda (conda-forge/staged-recipes#13520), we discovered the existence of this fork of Bliss.
Beforehand, we had started our own fork ds4dm/Bliss, as it seems the original authors were not interested in maintaining this project.
We believe we should join efforts to make this project easier to use for all of us.
Here is a list of what we have been working on, and would like to improve:
The first patch used by the SCIP developers was to be able to limits number of search nodes and generators during the backtrack search (ds4dm/Bliss@faeb2d2). This is something that we need to keep on our end, so hopefully we can find a way to merge it without changing API.
