SpletMinimum Cost Maximum Flow. Minimum Cost flow problem is a way of minimizing the cost required to deliver maximum amount of flow possible in the network. It can be said as an extension of maximum flow problem with an added constraint on cost (per unit flow) of flow for each edge. One other difference in min-cost flow from a normal max flow is ...
