Hi Simran, Thank you for your fast answer! My optimization procedure in summary consists of the following : -Runs suboptimal model without constraint in while loop; -Add constraints in part, until ...

Hi, Would it be possible to run the same model in consecutive optimizations? removing from the previous constraint, then running again, without the last optimization being influenced by the removed...

Hallo gurobot!  The question is :  GRBVar x;GRBLinExrpr b;GRBQuadExpr c;GRBLinExpr d;c=6*x;d=x+x;b= c+d; The solver does not accept, the sum of expr can be easily a LinExpr, but  I think is because...

Hi Matthias, The problem is my array P_wind is one single function output, that was randomly chosen from one data  2-D array [T][N] that will be the Upper Bound (UB) for the Gurobi variable W_curt[...

I already had noted my mistake but Thanks a lot!   

Hallo Jaromil, Yeah ... because if I join it then I get the error message about the list of arguments. "subproblem1 cb = subproblem1(P_wind,t_D_f,Pbss,Pbssd,Ecurrent); Severity    Code    Line    D...

Hallo Jaromil,   I think we mismatch answers and questions please find above the piece of my callback.

Hallo Jaromil,    Please find below the instantiation of part of the callback, that will be applied at the solution node. After I commented Ecurrent expression, then the optimization runs, without ...

Hi David, Really thanks for your answer!  "In the logs, you are showing, the optimality gap has not reached that point", so why the optimization has stopped if no time limit was set? BR, Alessandra.

Hi David, Thanks for your answer , time_limit was reset with : GRB_DoubleParam_TimeLimit, GRB_INFINITY About the MIP_GAP, please see below part of .log file for the same problem, the first one with...
