Hi, How can I implement a constraint so that resources from facility is sent to customer only when that facility is open?  select is a binary variable to send resource r from station s. deploy is a...

Hello good people, How can I correctly write/save the model.lp file to store non-binding constraints as well? When I write the model.lp file, most constraints are found formulated as expected. Howe...

Hello,  model.objval prints only the optimal objective value. But, I need values of objective function for both optimal (and non-optimal) solutions.     

Is there any API or tools in Gurobi to generate the math equation of constraints based on the Python script of that constraint? I want to get the math formula of the following constraint: model2.ad...

In my current optimization model, I have 3 binding and 6 non-binding constraint. So, I want to perform a detail sensitivity analysis to see if there is any loophole in the model formulation. Is the...

I am trying to implement a constraint of the maximal coverage problem (Equation 16.2 from the image at the bottom of this post). A minimal Python code is below.  But the code is giving me error Key...

I need to show the model structure/equation to the Jupyter notebook.  I wrote the model into local file (using mps, rlp, lp). Here is the model structure if I open it in text editor. I want to show...

One of my constraints of the optimization model is as below. Once optimal solution is found, I am able to remove some variables & (re)optimize the model. But, I also want to update the value of par...

I have the following list of Gurobi decision variables. <Gurobi.Var DV[May2021, Journey1]>, <Gurobi.Var DV[May2021, Journey2]>,<Gurobi.Var DV[May2021, Journey3]>,<Gurobi.Var DV[june2021, Journey1]>...

Hello good people, I am aiming to recalculate (&update) parameters value after each (or possible) iterations if x=1. How can I update value of parameter during model iteration? In the given problem...
