Flow network cut

WebIn a network flow problem, it is useful to work with a cut of the graph, particularly an s-t cut. An s-t cut of network \(G\) is a partition of the vertices \(V\) into 2 groups: \(S\) and \(\bar{S}=V\setminus S\) such that \(s\in S\) and \(t\in \bar{S}\). ... (Max-flow min-cut theorem).
