[SCIP] Problem in getting dual solution with SCIPgetDualsolLinear in my maximization problem

[‪Amir Mansouri‬ ‪]

Hi,
I want to get dual solution to computing reduced cost in the my maximization problem but the solution is 0 for all dual variables. I am sure that my maximization problem is solved correctly and the form of all of my constraints is aTx<=0 and they are linear constraints.
Can anyone help me?
 Best Regards,
Mansouri
