  • Suppress console outputs


    Hello, How do I suppress all console outputs when using Thanks, Xinshuo

  • Retrieve removed variables after presolve


    Is there a way to retrieve the removed variables (especially the binary variables) after presolve for MIP? I assume the values of those variables have been determined by the presovle and should be ...

  • How to make a deep copy of a linear expression using gurobipy


    I need to make changes to my objective function, solve the model and reset the objective function to be the original one. Since my objective function is a LinExp, I was wondering how to make a deep...

  • multiple scenario model running time


    I am using GUROBI multiple-scenario model to solve a MIP with small perturbations from a base model. I know the solution to the base model. So I use var.VarHintVal or var.Start (not both) to guide ...

  • MIP with infinite number of feasible solutions


    I have a MIP where two continuous variables x and y are equivalent. So in the solution the sum (denoted by s) of x and y is determined/fixed, but there are infinite many choices of feasible solutio...

  • Checking new RHS in multiple Scenarios


    I am using the multiple scenario Gurobi model in Python where in one of the scenarios I changed the RHS by: constr.ScenNRHS = new_RHS   Now I would like to see whether this change has been success...

  • Sensitivity analysis for input parameter in LP


    Does GUROBI support sensitivity analysis for input parameters in LP model?
