Hi Hamza, Gurobi unfortunately does not have tools for creating stochastic models from deterministic ones.The solver has the Multi Scenario feature but this is basically a sequence of deterministic...

Hi Panagiotis, The KeyError does not seem to originate from Pyomo or Gurobi, it seems to be come from the data structures you obtain (dicts, pandas dataframe). Did you check how the data structures...

It looks ok in terms of syntax, what is the error you get?

Hi, Could you please post the code for the balance constraints that you already have and that does not work? Then we can see if we can spot the mistake. Best regards,Mario

Hi Yuankai, We usually do not transfer academic licenses from one machine to another. Just create a new license for the new machine (in Gurobi's User Portal). Alternatively, you could create a WLS ...

Hi Mohammad, Your code snippet is a bit confusing for me, e.g., variable job_tardy is never used after creating it.Additionally, you are using GRBQuadExpr, does your model contain quadratic terms?I...

Hi, Gurobi's branch-and-bound algorithm is based on node relaxations (relaxing integrality), and involves a lot of other strategies that deviate from classical textbook branch-and-bound algorithms....

Hi, Here are some resources that you could use to formulate your model: Small code examples in Python Different modeling approaches for basic VRP variants in Python Gurobi Python Tutorials on Yo...

Hi Viktor, To fully understand your issue with the formulation: In each time step you have 2 non-negative variables, one for charging and one for discharging. You currently obtain solutions that e...
