I seem to have solved this problem for example:  I_1 = [1,2,3,4,5]I = [2,3,4,5]N = model.addVars(I, vtype=GRB.BINARY, name="N")F = model.addVars(I_1, vtype=GRB.BINARY, name="F")model.addConstrs(N[i...

another question, because I previously attempted to write this way by: model.addConstrs((N[k]>=F[k]-F[k-1] for i in range(k-1,k) for k in I),name="Constr2")  and error is  name 'k' is not defined A...

thank you
