Looping flow control is a crucial mechanism in controlling the flow of data in a network. It allows for efficient transmission of data across multiple devices, such as routers and switches, by optimizing the flow and rate of traffic. When it comes to network flow control, one of the key considerations is the management of TCP and UDP traffic.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).Network Flow Algorithms.

The flow across any cut equals the flow of a network. In our previous example, the flow was 19. Consider the flow across the cut Vs = {s, a, b}. We have three forward edges with flows of 8, 4, and 15 and two backward edges with flows of 1 and 7. Summing, we have 8+4+15-1-7 = 19, as desired.

A team of computer scientists has come up with a dramatically faster algorithm for one of the oldest problems in computer science: maximum flow.

(f ) = c(A; B). Max-Flow Min-Cut Theorem: in every ow network, the maximum value of. s-t ow is equal to the minimum capacity of an s-t cut. Given a time. In every ow of maximum value, we can compute a minimum s-t cut in O(m) ow network, there is a.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.

Network flow: definitions • Capacity: you can’t overload an edge • Skew symmetry: sending f from uÆv implies you’re “sending -f”, or you could “return f” from vÆu • Conservation: Flow entering any vertex must equal flow leaving that vertex • We want to maximize the value of a flow, subject to the above constraints Network Flow Problems with Electric Vehicles.
