MathOptimizer Professional (MOP) is a Mathematica interface to the LGO global optimization software developed by Janos Pinter
LGO uses compiled code for high speed optimization. Versions of MOP using the MingGW GCC compiler, the G95 compiler and Microsoft Visual Studio are available. There is also a free demo version using G95 that can handle up to 10 variables and constraints. Interested parties can contact me at frank@physicistatlarge.com . A Mathematica notebook describing the features of MOP and showing example problems is attached.
