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 flow … WebAn adjacency list is a hybrid between an adjacency matrix and an edge list that serves as the most common representation of a graph, due to its ability to easily reference a vertex 's neighbors through a linked list. Through the use of adjacency list, it is easy to look up a node's neighbors in constant or O (1) time.
