Strange log: infeasible root relaxation, feasible MIP
AnsweredHello, I am getting a strange log with the MIP I'm trying to solve. The MIP is feasible, as proved by the optimal solution displayed below. However, the log says "infeasible" for the root relaxatio...

Issue with warm-start after changing rows
AnsweredSometimes I need to change the variable coefficient of a constraint and then reoptimise from the previous solution. Whenever this change makes the problem primal infeasible, the dual simplex doesn'...

Primal and dual simplex
AnsweredHow does Gurobi go about re-optimising an LP model when we add both rows and columns to the model from the last solve? Does it do it sequentially, i.e. add columns -> warm start primal simplex -> a...
