Cc: sage-support@googlegroups.comHi - I was asking for some capability to do integer programming (not linear programming) via Sage. I don't believe that cdd does this. But let me know if you know otherwise. T here appears to be some packages at http://www.zib.de/Software/ that might be good if the licenses agree. For instance, I think SoPlex was in some version of Gfan. It might still be there. SCIP seems to an IP solver. If you know of others, I'd be interested to know. It would be great if Sage could do both linear and integer optimization. -Rekha On Tue, Apr 1, 2008 at 12:25 AM, William Stein <[EMAIL PROTECTED]> wrote: > On Mon, Mar 31, 2008 at 7:56 PM, Marshall Hampton <[EMAIL PROTECTED]> wrote: > > > > Hello, > > > > What do you want to do with polymake?
