So … WebOct 3, 2024 · The single-source shortest path issue for a directed graph G = (V, E) with non-negative edge weights is solved by the greedy algorithm known as the Dijkstra algorithm, which bears the name of its discoverer, Dutch computer scientist Edsger Dijkstra. In other words, we suppose that for any edge (u, v) є E, w (u, v) ≥ 0.

The Ford–Fulkerson method or Ford–Fulkerson algorithm (FFA) is a greedy algorithm that computes the maximum flow in a flow network. It is sometimes called a "method" instead of an "algorithm" as the approach to finding augmenting paths in a residual graph is not fully specified or it is specified in several implementations with different running times. It was published in 1956 by L. R. Ford Jr. and D. R. Fulkerson.
