WebMinimum 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 ... WebThere are a number of real-world problems that can be modeled as flows in special graph called a flow network. a flow network is a directed graph whose edges are labeled with non-negative numbers representing a capacity for a flow of some kind: electrical power, manufactured goods to be distributed, or city water distribution.
