WebAbstract. In Graph Theory, maximum flow is the maximum amount of flow that can flow from source node to sink node in a given flow network. Ford-Fulkerson method implemented as per the Edmonds-Karp algorithm is used to find the maximum flow in a given flow network.. Scope of the Article. Maximum flow problem has been introduced, … WebOne of the classic problems in graph theory is to find the shortest path between two vertices in a graph. ... A flow network is a directed graph G=(V,E) with a source vertex s and a sink vertex t. Each edge has a positive real valued capacity function c and there is a flow function f defined over every vertex pair. The flow function must ...

Graphs can be used to model many types of relations and processes in physical, biological, social and information systems. Many practical problems can be represented by graphs. Emphasizing their application to real-world systems, the term network is sometimes defined to mean a graph in which attributes (e.g. names) are associated with the vertices and edges, and the su…
