  • How to execute for-loop iterations in parallels in MATLAB using Gurobi as a solver?


    Hello, I have a MIP problem, which I decomposed into subproblems, and I want to solve these subproblems using Gurobi in MATLAB. The only thing that changes in each subproblem is the objective funct...

  • The objective bounds improve slowly!

    Hello, I have a SOC programming problem, which I try to solve. It takes to much time to find an incumbent objective bound, and when it finds one, it improves slowly. I tried different parameters, b...

  • Gurobi and second- order cone constraints.


    Hello, I have SOC constraints set in my model, and Gurobi can not solve it. I guess it could relate to the format of the constraint (the linear part), but I am not sure. This is the constraint: wh...

  • A big gap after 3 hours run!

    Hello, I have a problem that I tried to reformulate as a second-order cone programming problem, and I have a time limit of 3 hours, but after the code terminates, the gap is too big (80%). I know t...
