DICOPT: Serious problems in MIP master problem
Posted: Fri Feb 18, 2022 9:05 pm
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.
