WebThe All Pairs Shortest Path (APSP) calculates the shortest (weighted) path between all pairs of nodes. This algorithm has optimizations that make it quicker than calling the Single … WebAdd u to S, marking u as visited. For each node v which is adjacent to u, update dist[v] as − If (dist[u] + weight of edge u-v) < dist[v], Then Update dist[v] = dist[u] + weight of edge u-v The array dist[] contains the shortest path from s to every other node.
