The … 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.
