WebJul 5, 2024 · The Floyd-Warshall algorithm basically works on a v * v adjacency matrix. It considers every vertex and decides what would be the shorter route if could you go via that vertex. This is a constant time comparison and an insert-operation (into a 2D array) carried out for all v^2 elements of the matrix. This needs to be performed for every vertex. WebThe value of C[i][j] is 1 only if a directed path exists from vertex i to vertex j.Note that all diagonal elements in the connectivity matrix are 1 since a path exists from every vertex to itself.. Practice this problem. Method 1. As discussed in the previous post, we can use the Floyd–Warshall algorithm to find the transitive closure of a graph with V vertices in …
