Hi Simranjit, I can run the code:  for c in model.getConstrs():    print(c.IISConstr) But I cannot run: for c in model.getConstrs():    print(c.IISQConstr) OR for c in model.getConstrs():    print(...

Thanks for the help, Riley. So basically I have to put the for loop outside of the logarithm constraint function. that is the difference between this type of constraint with the rest of the constra...

No I know how to define x, and y. They are multi-parameter variables and from what you say I have to put the for outside of the logarithm function. That was something I was not aware of. You have a...

Hi Riley, I think I have found the solution. I have put a one note with the explanation and my question in the Dropbox link. And the new version of my code named Benders new. The modeling explained...

Hi Riley, my code is in this folder in dropbox: https://www.dropbox.com/scl/fo/0w8bt6jue8dn5cykewa94/h?dl=0&rlkey=2h1vvq0plpt8b6rl8pepehtos There are 2 excel files that it reads. You do not have to...

Hi Riley, I have found a way to go around all these, my problem is how to set a logarithmic equation with parameterized variables. I cannot find this. Do you know how I could make the below code wo...

Hi Riley, Another example to make myself clear is: suppose I have the constraint: Can I create a function f that takes as input R_i, R_w and returns their log difference and then set this function ...

What I mean is instead of writing the first equation as a non-linear constraint in the optimization model(that I suppose is impossible), I am wondering if I could make it a function and then use th...

Hi Riley, By the same logic if I have a non-linear function like the below:where x_a is variable and P_a and t_{0,a} are parameters. Can I define it not as a model constraint but as a function and ...

I want the input of the function to be: a,k,i,r,s and the output 0/1. If I define this function somewhere in my code in the initial stages can I later use it in the constraint of the optimization m...
