WebApr 19, 2024 · MaxFlow. The maximum flow problem is an optimization problem seeking the feasible flow through a single-source, single-sink flow network. A flow network G= (V, E) is a directed graph where each edge (u,v) in the graph, has a capacity (c >=0 ). A flow network must follow these properties; there are no self-loops, there are a single source … WebMar 25, 2024 · The max flow problem is a flexible and powerful modeling tool that can be used to represent a wide variety of real-world situations.
