DICOPT: Serious problems in MIP master problem

Post by Ebru »

Hello experts,

I'm always opening a new toic in last days, so I apologize, but unfortunately I need to solve this GAMS problem for my doctoral thesis. I am just getting familiar with GAMS.

I have a nonlinear problem and this problem also includes binary variables. The solvent used is DICOPT. I think DICOPT consists of two basic phases, NLP and MIP. A solution cannot be produced at the MIP stage. Here's the warning GAMS gave me:
DICOPT: Serious problems in MIP master problem

And none of my binary variables are getting binary values. How can I fix this problem?

I'm very stuck, if you can help me I would be very grateful.
