Hi,
I'm looking for software (open source preferable) with python
interface preferable (otherwise may be c or c++) to solve an
optimization problem with non linear objective function and
constraints and mixed real and binary variables.
I've seen GLPK but it seems don't support non linearity, and CVXOPT
but it seems don't support integer variables.

Thanks in advance,
H
