WebTheorem (Max-flow min-cut Theorem): The value of a maximum ( s, t) -flow equals the smallest possible value of an ( s, t) -cut. This means that if you can find an ( s, t) -cut with a value that equals the current value of the ( s, t) -flow, then the flow is definitely maximum. Since we've found an ( s, t) -cut with value 12, and you also have a ... WebGraph Theory 151. Graph Theory and Network Flows.

Web(Minty, 1966)) the duality is a very natural structure of network-flow theory, i.e., that "part" of network flow theory which can be stated in terms of concepts related to edges only without reference to vertices possesses a "dual" logical structure. This duality of the theory comes from the duality of graph theory, and every proposition for ...
