[SciPy-user] Need Help: Linear Programming

Hello Aditya,

If all you need is an LP solver, I have had a lot of luck with
lp_solve 5.5 (http://lpsolve.sourceforge.net/5.5/)..  It's a mature
package that I use heavily in my research and it works very, very
well.  It has a python wrapper, which isn't bad and is quite full
featured.  For what I'm doing, though, I've written a (simpler) cython
interface that works directly with numpy arrays and is great to use in
conjunction with numpy/scipy. The documentation is currently rather
sparse, but if you're interested I'll work on that a bit and send it
to you.   Note that it's LGPL, not BSD like numpy/scipy.

But my friend assures me that sine SciPy has a lot more complex
Non-linear programming solvers, there must be something for Linear
Programming in there but I am not able to find it.

Any help will be greatly appreciated.thi@gmail.com> wrote:
