Each tuple in R corresponds to a driver, with the first element in each tuple being the origin of the driver and the second element being the destination of the driver.  Each tuple in L corresponds...

Thank you very much ! This is clearer ! I followed your advice and proceeded as follows :  RL = [(r, l) for r in R for l in L]with gp.Env() as env, gp.Model(env=env) as model: x = model.addVars(le...

Thank you for your answer. The only issue I have is that I won't be able to refer to my variables using the tuples but I would have to use the 15th elemnt for example.  In order to refer to my vari...

Hi Ronald,  Could you give me an example ?  Suppose I have two lists of tuples :  R = [('e', 'e'), ('e', 'e'), ('a', 'a'), ('e', 'e'), ('d', 'd')]L = [('d', 'd'), ('e', 'e'), ('d', 'd'), ('c', 'c')...

Thank you very much for your answer !  Would this be the correct way to do it ?  for r in R: x = model.addVar(r, vtype=gp.GRB.BINARY)

Hi Ronald,  Thanks a lot for your answer.  I realize I wasn't very clear in my previous message.  I have a list of tuples :  R = [('b', 'b', 2), ('b', 'b', 2), ('e', 'e', 2), ('d', 'd', 2), ('c', '...
