Definition. A flow network is a directed graph G Æ (V,E) with distinguished vertices s (the source) and t (the sink), in which each edge (u,v) 2 E has a nonnegative capacity c(u,v). We require that E never contain both (u,v) and (v,u) for any pair of vertices u,v (so in particular, there are no loops).

If there is no such path P then f is a maximal flow for G′ (by the Lemma in the proof of the Max-Flow Min-Cut Theorem). Otherwise, e0 is on the path P. The residual capacity of e0 is c′ f(e0) = c′(e0) − f(e0) = 1. Note, since we used BFS, the path is a simple path and no edge appears twice or more on P. Therefore the bottleneckA flow network is defined by a weighted directed graph G = (V; E): 20 u. 10. s 30. s is the only source node. t is the only sink node each edge has a capacity nodes other than s or t. t are internal nodes. 10. 20.
