## Activity overview

• In addition to the above, maybe a slightly simpler problem can be considered. Again, I am trying to minimize the number of variables I am using in order to speed up the code. My eventual goal is to...

• Hello Steven. Thank you for your previous comment. I have a question about a slightly harder problem, in which I am trying to minimize the number of variables and constraints that I am using.  Here...

• ### How to determine how long it will take the simulation to finish?

Hello, 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?

Hello, 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: ----------------------------------------------------------------------...

• My apologies Steven. Here is what I mean.  As you can see I defined z to be dictionary first. Then I said that for each key in z, z[time_interval] is defined as a Gurobi variable, suing the .addVar...

• Thank you Steven. I restarted my kernel and got the same answer as you. Now I was wondering about something else. As you can see I am calculating y based on z, and z based on x, for every time inte...

• ### Why is this model infeasible?

Ongoing

Hello, 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] =...

• Hello Jaromil. Thank you very much for the suggestions. The problem ended up being consistently subtracting (step+1)/113880 term from D which makes it less than 0. I had another question. Is ther...
