Sage-combinat

Sage-combinat is a collection of experimental patches (i.e. extensions) on top of Sage, developed by a community in algebraic combinatorics. Its main purpose is to improve Sage as an extensible toolbox for computer exploration, and foster code sharing between researchers in this area. The intent is that most of those patches eventually will get integrated into sage as soon as they are mature enough, with a typical short life-cycle of a few weeks. In other words: just install Sage, and you will benefit from all the Sage-combinat development, except for the latest bleeding edge features.

NEWS

• July 25-29: *-Combinat 2009

  • We will hold an International Sage Workshop on Free and Practical Software for Algebraic Combinatorics at RISC, Linz, Austria, right after FPSAC'09.

• 2009-02-20: Submission of a software demonstration request for FPSAC 2009 PDF, LaTeX Source LaTeX bibliography

• January 26-30: Sage-Combinat Workshop in Orsay

• 2008-06-19: MuPAD-Combinat join forces with Sage

  • Sage-combinat was born as a partial port of MuPAD-Combinat. After months of discussions and experiments, an enthusiastic consensus emerged in the MuPAD-Combinat community to join Sage. Sage-combinat henceforth became the natural successor of MuPAD-Combinat.

  • The transition is going to be a massive investment: seven years of hard work to port over! However a lot of experience was gained since 2000, and most of the design is now pretty clear. By sharing the work the transition will hopefuly be relatively quick.

    See the road map and current status of the port.

How to participate and contribute

• Join our mailing list: http://groups.google.com/group/sage-combinat-devel.

• Post bug reports, suggestions, patches on the Sage-Combinat trac server or on the mailing list.

• Cite Sage-Combinat when you use it for research publications (TODO: provide a standard citation here).

• The collection of patches is managed using a patch server (mercurial queues). Use it to try out the latest experimental features, or contribute your own patches! (You may still need to access to the old patch server)

  • Step by step tutorial (in particular, how to download Sage-Combinat)

  • Technical background on the Sage-Combinat patch server (messy).

• Have a look and participate to design discussions.

• Contribute to the list of quirks and weirdness issues in the *-Combinat design.
