WebAlgorithm 9. Given a flow network ( G, c, s, t). Initialize f by setting f ( e) ← 0 for all edges. This is a valid flow. While t is reachable from s in G f: Construct the graph D by doing a BFS from s ( dinitz_bfs ). Use the blocking-flow algorithm ( dinitz_dfs) to find a flow Δ f in D ⊆ G f. Let f ← f + Δ f.
