Question

How to do tracing of algorith for floyd's algorithm?

Answer 1

 When solving practical transportation problems, it is often necessary to calculate the shortest path between all pairs of nodes in a transportation network. If the network has n nodes, then the Dijkstra algorithm must be applied n times, taking a different node each time as the starting node. This is a lengthy process. Hence, Dijkstra's algorithm is rarely used to determine the shortest  path between all pairs of nodes; instead Floyd's algorithm is used.
