GAMS returns unknow QCP status(13): unknown

Post by feifan »

Hi, all,

I used the GAMS/Gurobi solver to solve a QCP problem, and the solver got an optimal solution. But, GAMS returns unknow QCP status(13): unknown and no solution displays.

What happened here?

By the way, I also want to mention that GAMS/Gurobi solver and GAMS/Cplexd got different objective values although they all claimed that optimal solution was found. Why did it happen?

Thanks in advance!

Kind regards,
Feifan

Hard to say with this little information. You might want to post the log and lst, or even the model so someone can reproduce and check what's going on.
