[Numpy-discussion] [ANN] global constrained solver with discrete variables

hi all,
I've done support of discrete variables for interalg - free (license:
BSD) solver with specifiable accuracy, you can take a look at an example

It is written in Python + NumPy, and I hope it's speed will be
essentially increased when PyPy (Python with dynamic compilation) support
for NumPy will be done (some parts of code are not vectorized and still
use CPython cycles). Also, NumPy funcs like vstack or append produce only
copy of data, and it also slows the solver very much (for mature

Maybe some bugs still present somewhere - interalg code already became
very long, but since it already works, you could be interested in trying
to use it right now.

Regards, D.
