Definitions A network is a triplet 9'2 = (N, 94, c), where N is a nonempty finite set whose elements are the nodes, d is a set of ordered … WebA Flow network is a directed graph where each edge has a capacity and a flow. They are typically used to model problems involving the transport of items between locations, using a network of routes with limited capacity. Examples include modeling traffic on a network of roads, fluid in a network of pipes, and electricity in a network of circuit components.
