How to determine how long it will take the simulation to finish?
AnsweredHello, I have a model that can take multiple days to solve. I was curious if there is a feature in Gurobi that can tell me how long it should take the model to solve? An estimate up to a few hours ...

What kind of functions can be accepted into Model.setObjective method?
AnsweredHello, I have the following code where I am trying to find the value of 'x' for which the function below will be at a minimum: ...

Why is this model infeasible?
OngoingHello, I cannot understand why this model is infeasible? from gurobipy import Model, GRB solver = Model() X = solver.addVar(0, float('inf')) x = {}for time_interval in range(5):x[time_interval] =...

Gurobi says the model is infeasible, yet I can come up with a solution by hand. Python implementation
AnsweredHere is my model. Gurobi says its infeasible. My apologies if its hard to follow. f = Model() num_steps = 3 steps = [*range(num_steps)] steps_for_C = [*range(num_steps + 1)] A = f.addVar(0, float...

Gurobi says model is 'infeasible' but when I run solver.computeIIS() gurobi says it cant be computed because the model is feasible
AnsweredGurobi says model is 'infeasible' but when I run solver.computeIIS() Gurobi says it cant be computed because the model is feasible. Why is this?
