Riley Clement thanks for the response and it definitely helps. Makes sense how the solver is handling things internally. For LP warm start with the Start attribute, I was adding a dummy binary as M...

My temporary fix has been to add a single binary variable to the model, forcing Gurobi to use the variable start attributes since it is now technically a MIP. I am still hoping for a better resolut...

LP Warm Start (Python)
オープンI have an LP implemented with gurobipy. First, it takes 38 simplex iterations to reach optimality. Then, I immediately invoke optimize on the same instance to confirm that the previous solution is ...

Omit Variable in Branch and Bound
回答済みIf I have a model with two integer variables: Y_i: integer time to schedule activity i X_it: binary indicator if activity i is scheduled in time t How can I communicate to Gurobi (prefer...
