No error nor solution reported

Hi, there

My model is trying to solve the same model by updating one variable U,as in line 196 and 199 in my code:

UR(I,J) = max(0, URP(I,J)+theta*(TF1.L(I,J) - RW(I,J,“Capacity”)))
UH(I,J) = max(0, UHP(I,J)+theta*(TF1.L(I,J) - HW(I,J,“Capacity”)))

When I ran this model, there is no error reported and no solution reported ( not due to infeasibility). The serve status is normal completion. My code is attached here. Any comment is highly appreciated.

Hi Peyiu

It is not solving the model, because you have at the beginning of the loop iter$count with count equal to zero. So no looping at all.

Set count equal to 1 and it solves fine.

Hi Peiyu



You have count equal to 0 at the start of the loop, so the loop is not executed because of iter$count.

Set count equal to 1 and the model runs fine.
