WebThe maximum flow problem can be seen as a special case of more complex network flow problems, such as the circulation problem. The maximum value of an s-t flow (i.e., flow from source s to sink t) is equal to the minimum capacity of an s-t cut (i.e., cut severing s from t) in the network, as stated in the max-flow min-cut theorem. duties of commi 3

Cuts A cut is a partition of vertices (V s, V t) such that the s V s and t V t. An edge that goes from u to v is a forward edge if u V s and v V t. If the opposite is true, then it is a backward edge. 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).
