WebApr 12, 2024 · All-pairs. All-pairs shortest path algorithms follow this definition: Given a graph G G, with vertices V V, edges E E with weight function w (u, v) = w_ {u, v} w(u,v) = wu,v return the shortest path from u u to v v for all (u, v) (u,v) in V V. The most common algorithm for the all-pairs problem is the floyd-warshall algorithm.
