In http://ask.sagemath.org/question/3282/ it was revealed that in Sage, the MILP interface defaults (like most such software) to assuming nonnegative variables as a constraint, which they has to be explicitly undone. It looks like the (possibly unrelated) linear_program command also does this. This is natural in that world. However, Nathann did a little digging upon my request and discovered that Matlab and Maple apparently (?) don't assume this.
So... should we change our interface? Or should we keep it the same as it was? I can think of arguments for both. Input would be appreciated, especially from those who have actually used this functionality (perhaps in contexts not "about" LP). - kcrisman -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
