Web16.2 The Network Flow Problem We begin with a deﬁnition of the problem. We are given a directed graph G, a start node s, and a sink node t. Each edge e in G has an associated non-negative capacity c(e), where for all non-edges it is implicitly assumed that the capacity is 0. For example, consider the graph in Figure 16.1 below. 2 4 3 3 2 4 1 ... WebApr 5, 2024 · A 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 ...
