3. In the min-cost max-flow problem defined on a directed network

3. In the min-cost max-flow problem defined on a directed network $G= (N, A)$, we wish to send the maximum amount of flow from a node $s$ to a node $t$ at the minimum possible total cost. That is, among all maximum flows, find the one with the smallest cost. Show how to formulate any minimum cost flow problem as a min-cost max- flow problem. CS.VS. 984
