WebMay 12, 2024 · In graph theory, a flow network is defined as a directed graph involving a source(S) and a sink or a target(T) and several other nodes connected with edges. Every edge in a flow network has a capacity associated with it. Capacity of a flow network is defined as the maximum limit of flow that is possible along a given edge. WebIn computer science and optimization theory, the max-flow min-cut theorem states that in a flow network, the maximum amount of flow passing from the source to the sink is equal to the total weight of the edges in a minimum cut, i.e., the smallest total weight of the edges which if removed would disconnect the source from the sink..
