the Network Flow Problem. Network flow is important because it can be used to model a wide variety of different kinds of problems. So, by developing good algorithms for solving flows, we get algorithms for solving many other problems as well. In Operations Research there are entire courses devoted to network flow and its variants. 14.2. THE NETWORK FLOW PROBLEM 59 Our goal is to push as much flow as possible from s to t in the graph. The rules are that no edge can have flow exceeding its capacity, and for any vertex exceptfors and t,theflowin to the vertex must equal the flow out from the vertex. That is, Capacity constraint: On any edge e we have f(e) ≤ c(e). Analysis. Assumption: capacities are integer-valued. Finding a flow path takes Θ(n + m) time. We send at least 1 unit of flow through the path If the max-flow is f⋆, the time complexity is O((n + m)f⋆) “Bad” in that it depends on the output of the algorithm. Nonetheless, easy to code and works well in practice. the Network Flow Problem. Network flow is important because it can be used to model a wide variety of different kinds of problems.
