Flow in graph theory

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 ... WebNetwork Flow Problem Settings: Given a directed graph G = (V,E), where each edge e is associated with its capacity c(e) > 0. Two special nodes source s and sink t are given (s 6= t) Problem: Maximize the total amount of flow from s to t subject to two constraints – Flow on edge e doesn’t exceed c(e)
