    DeprecationWarning: elementwise comparison failed

    Hi, I was hoping that one of you might be able to shed some light on the following warning message that I have been getting. Optimal solution found (tolerance 1.00e-04)Best objective 0.000000000000...

    Dead kernel

    回答済み

    Dear community, I came across something rather annoying :) When I execute the optimization problem, the solver ends with an optimal solution. Then I extract the solution and try to print/ plot them...

    Select variables in feasRelax()

    回答済み

    Dear community, In the Model.feasRelax() documentation the model.getVars() is used to assign the set of variables whose bounds are allowed to violate when calling feasRelax(). But what if I want to...

    SOS constraint problem

    回答済み

    Dear community, I'm trying to model the part-load efficiency (cop) of a heat pump as a function of the installed capacity and the load-level. In a simple case, let's take that the installed capacit...

    Thank you Eli. So I added (with Gurobi 9.0); model.Params.NonConvex = 2 model.addConstrs(v_hp_load_level[T]*v_hp_power[T] == v_installed_capacity for T in Time) There were some problems but after I...

    Part-load efficiency curve modelling in Gurobi

    Dear community, I would like to model the efficiency of a heat pump as a function of its load level, e.g., efficiency(T) = a*load_level(T)+b, where a and b are constants and T is time.  I have two ...
