General nonlinear mixed integer problems

Hello,

 

I'm trying to solve a nonlinear mixed integer problem (quadratic objective function, quadratic constrains, non convex, mixed integer) using mmxnlp, but I'm getting a feasible solution that is not optimal, I found a solution that is better that the one Xpress is giving. Can Xpress solve this kind of problems? If yes, why am I getting this wrong solution?

 

Thank you very much.
