Flows in networks

WebA graph flow is, in its simplest formulation, a labelling of the directed edges with real numbers subject to various constraints. A common constraint is conservation in a vertex, meaning that the sum of the labels on the incoming edges of this vertex equals the sum of those on the outgoing edges. One easy fact is that if a flow is conserving in ...

Flows in Networks - Lester Randolph Ford Jr., D. R. Fulkerson

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. Web1 Network Flow A network N is a set containing: a directed graph G(V;E); a vertex s 2V which has only outgoing edges, we call s the source node; a vertex t 2V which has only …
