Floyd-Warshall Algorithm Explained
in this video, the Floyd-Warshall Algorithm for finding the shortest path between any pair of nodes in a graph has been explained visually. Here we use the adjacency matrix of the graph and update it iteratively by checking a shorter path via Each node and if a shorter path is found we update the matrices. We repeat this for all the nodes ...

Floyd-Warshall Algorithm Example
How would you modify the Floyd-Warshall algorithm on a weighted, directed graph G = (V,E) to solve the following problems? Carefully justify your answer in each case:a) Find the number of shortest paths between each pair of vertices.b) Find the number of simple paths of even length and of odd length between each pair of vertices.
