WebMaximum (Max) Flow is one of the problems in the family of problems involving flow in networks.In Max Flow problem, we aim to find the maximum flow from a particular source vertex s to a particular sink … WebFirstly, we create flow graph G as mentioned in Section 4. As we know, the key to solve the problem using the network flow is to map the problem into the network flow graph. MVMFA is based on the classical network flow method of Ford–Fulkerson. The basic idea of MVMFA is to find the augmenting path iteratively with a bigger ρ:
