    I have to solve in each iteration a cluster that is in dict_F_l. This dictionary has the cluster key and the values ​​of the farms that I need to solve in each iteration. Thus, in the first iterati...

    3. Change sets in a optimization loop

    I see...thank you soo much for this analogy! It's very clear to me now. There is anyway that is possible to define sets dynamically into the loop? (Uptading all model)

    Sorry... I believe that the message above is not clear enough... Unfortanelly this strategy (model.copy) don´t work to mee.... I give this error: AttributeError: Unable to retrieve attribute 'x'   ...

    3. Change sets in a optimization loop

    I need to build the large model once and, solved it in each iteration only the variables associated to pair (key, value) of my dictionary. This strategy is based in decoposition. My problem has ten...

    2. Programming

    I had large problem to solve and, I´m decided to create a methaeuristic for decomposit it. Basic I have to redefine 2 sets in a loop: print(dict_F_l.items()) dict_items([(0, [6, 8, 9]), (1, [5, 7...

    3. Change objective function during optimization

    Hi Jaromil, a have a similar problem. I need to delete and insert the same objective function during each iteration in the loop of the rolling horizon. I  coded my model in Pyomo framework and used...
