As early as in 1950s, Ford and Fulkcerson proposed an algorithm to find maximum flow in a network. In this study I presented the full codes of Ford-Fulkcerson algorithm and given an application example. http://www.iaees.org/publications/journals/ces/articles/2018-8(2)/finding-maximum-flow-in-the-network.pdf
