Abstract

The MULTICOMMODITY FLOW PROBLEM is a generalization of the MAXIMUM FLOW PROBLEM. Given a digraph with edge capacities, we now ask for an s-t-flow for several pairs (s, t) (we speak of several commodities), such that the total flow through any edge does not exceed the capacity. We specify the pairs (s, t) by a second digraph; for technical reasons we have an edge from t to s when we ask for an s-t-flow.
