1:

Input: G = (V, E), N (number of controllers), Constraints (e.g., capacity of links)

2:

$MinCost\leftarrow \infty$

3:

For each solution k in the set of possible solutions Do

4:

Assign the set of controllers in k to network devices

5:

$Cos{t}_k=CostFunc\left(G,k\right)$

6:

If ( $Cos{t}_k<MinCost$ ) and (Constraint Check) Then

7:

$MinCost=Cos{t}_k$

8:

End If

9:

End For

10:

Return N Controller Placements, Controller Assignments, MinCost
