WebMay 28, 2012 · Option 2: 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. WebJan 6, 2024 · Floyd's algorithm is basically this algorithm with additional considerations about such weights. Given an n x n adjacency matrix G representing a directed graph, its transitive closure is a boolean n x n matrix where the entry at (i, j) is equal to true if and only if there is a directed path from vertex i to vertex j.
