This algorithm is used to find the shortest path between every pair of vertices in a given edge graph. Let G = (V,E) be a directed graph with n vertices. Let cost be a cost adjacency matrix for G such that cost (i,i) = 0, 1<=i<=n.

WebPerhaps because of this, the first algorithm for all-pairs shortest paths (in the 1960's) by Floyd based on Warshall's work took a dynamic programming approach. (We'll get to that later.) But then Johnson had a bright idea in 1977 that salvaged the greedy approach.
