Run the network stream first, then Tarjan in the remaining network.Consider an edge (U,V):When and only if scc[u]! = Scc[v], (u,v) may appear in the smallest cut ... But I'm not going to proveWhen and only if scc[u] = Scc[s] scc[v] = = Scc[t], (U, v) must appear in the smallest cut. This is a good brain tonic, if this side is not full flow, then s-t there is an augmented road.------------------------------
