The "Search and Shortest Path" section could also include other functions about paths and cycles : sage: g = digraphs.Circuit(4) sage: g.all_ g.all_cycles_iteratorg.all_simple_cycles g.all_paths g.all_simple_paths g.all_paths_iterator The only problem is that these functions are

Hi ! Thank you for the detailed answer. It will help to find someone who could work on the Windows port and I'm glad it seems reasonable to ask a good undergraduated student in computer science to do the job, at least partially. Alexandre -- To post to this group, send an email to sage-devel@go

[sage-devel] Windows port status

2011-04-14 Thread Alexandre Blondin Massé
Hi, all! I know this is a recurrent subject, but I was wondering what was the status about the Windows port. As many other users/developers of Sage, I promote it the most I can but one obstacle that keeps showing up is that it does not work natively on Windows. I know that there is the VMWare solu

2011-02-16 Thread Alexandre Blondin Massé
Hi, everyone! I'm interested in including a Sage module that allows one to handle systems of equations on words. For instance, if one wants to find all solutions of the equation u = ~(u) (where ~ means the reversal of the word, i.e. rewriting it in the opposite order), one should get the palindrom
