Max flow example

WebExample edit A maximal flow in a network. Each edge is labeled with f/c, where f is the flow over the edge and c is the edge's capacity. The flow value is 5. There are several minimal s - t cuts with capacity 5; one is S = { s, p } and T = { o, q, r, t }. The figure on the right shows a flow in a network.

The value of Δ is determined by the bottleneck of P; that is, the edge with minimum available capacity. Formally, Δ = min e ∈ P ( c e − f e). Go to step 1 until no augmenting paths exist. That is, find a path with available capacity, send flow along that path, and repeat.
