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.

WebThe flow of the network is defined as the flow from the source, or into the sink. For the situation above, the network flow is 19. 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. supported partnership cspThe simplest and most common problem using flow networks is to find what is called the maximum flow, which provides the largest possible total flow from the source to the sink in a given graph.
