Multicommodity Flows and Edge-Disjoint Paths,The . is a generalization of the .. Given a digraph . with capacities ., we now ask for an .-.-flow for several pairs (.) (we speak of several commodities), such that the total flow through any edge does not exceed the capacity.

Spanning Trees and Arborescences,uffice to connect all cities and they should be as cheap as possible. It is natural to model the network by a graph: the vertices are the cities and the edges correspond to the cables. By Theorem 2.4 the minimal connected spanning subgraphs of a given graph are its spanning trees.
