WebFord–Fulkerson algorithm is a greedy algorithm that computes the maximum flow in a flow network. The main idea is to find valid flow paths until there is none left, and add them up. It uses Depth First Search as a sub-routine.. Pseudocode * Set flow_total = 0 * Repeat until there is no path from s to t: * Run Depth First Search from source vertex s to find a … Web27 mei 2024 · The bipartite graph is super “simple” in the beginning. This causes the shortest path problem to become “harder”, that is, to involve more edges in the residual graph as we send more flow, and this impacts D´Esopo-Pape greatly.)
