I have a program written in App Engine (python) and I want to use an integer linear programming solver in it. All solvers I could find seems to be written partly in C, so I would imagine they won't work in App Engine.

Anyone knows of a pure python library that solves integer linear programming with inequalities?

I managed to find this http://projects.scipy.org/scipy/ticket/1252 but it seems that it doesn't deal with inequalities.

  • Have you tried the ones you've found? (could you link to them in your question?) Commented Sep 22, 2012 at 10:56
  • I just downloaded whatever I could find on stackoverflow / wikipedia and checked if they have c files. All of them did. Commented Sep 22, 2012 at 12:33
  • And those would be helpful links to include in your question (see whathaveyoutried.com). My point was "you don't imagine they'd work in app engine", I think they will, did you try?? Commented Sep 22, 2012 at 14:09
  • I have reason to believe they won't work (developers.google.com/appengine/docs/python/runtime#Pure_Python), so I am not interested in investing the time in trying. If you think otherwise you are welcome to post an answer/comment and say why. Furthermore maybe it would be better to keep your general views about the culture of asking questions in meta/up and down votes. Commented Sep 22, 2012 at 15:42
  • I think that is more relevant to writing your own C extensions... Commented Sep 23, 2012 at 1:32
