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!
