Hi!

I’m using Gurobi in combination with Python. My model contains several variables that have a lower bound of zero. I added these by using the lb=0 parameter to the addVars() method (although I know that this is unnecessary as the lb of 0 is default). When I use model.write() and inspect the bounds, the lower bounds of these variables are not printed. Is this a design choice of Gurobi as lower bounds of zero are default? Or is this a sign that something is wrong with my model?

Thank you!

kind regards

  Hi,

  This is expected behavior, the zero lower bounds of the variables are not printed because they are default.

  Best regards,

  Elisabeth
