Can you vectorize Decision Variable and Constraint generation in Python

[taylor leonard]

Hello, 

I generate a large number of iterations of various MIPs and am curious if there is vectorized code in Python for generating the Decision Variables and Constraints, or if they all need to be looped through individually.

Thank you, 

Taylor

Hello Taylor,

you can create whole batches of decision variables in gurobipy using the Model.addVars() function.  If you can phrase batches of your constraints as a generator expression, you can add them all at once to the model using Model.addConstrs() function.

Best,

Robert

Hi Robert, 

Thank you for the reply and the solution, I should have been able to figure that out.  I've already implemented it and it works great.  

Thank you,
