Hello, Almost a year ago there was a brief discussion about this topic:
http://groups.google.com/group/sage-devel/browse_thread/thread/fed15c54478e8d5 GLPK is a GPLv3 program from the FSF for linear programming: http://www.gnu.org/software/glpk/ Many of the awesome graph theory functions (such as for Hamiltonian graphs) depend on some LP program being installed, and I think it would be great if sage-standard could, e.g. solve the is_hamiltonian question. Here are a few William Stein quotes from the last discussion: > NOTE: GLPK is GPLv3. Since we need to retain the ability to release GPLv2 > versions of Sage for now, this is another very good reason to make it > optional for a while (so it is easy to swap out). ... > I personally think GLPK will end up being standard in Sage before > long, so I think your approach right now is pretty good. It's just > that it has to be optional for a bit (a month or so), since that's > what we do. I recently emailed him about the GPLv3 issue, asking "is GPLv3 a deal-breaker?" and he replied "No, it is not a dealbreaker." As more and more functions requiring LP get merged into Sage, I think the time has come to reconsider this. -- Robert L.
