   What is Floyd-Warshall algorithm?

   • Floyd-Warshall Algorithm is an algorithm for finding the shortest path between all the pairs of vertices in a weighted graph. This algorithm works for both the directed and undirected weighted graphs. But, it does not work for the graphs with negative cycles (where the sum of the edges in a cycle is negative).

   What is the time complexity of Floyd-Warshall algorithm?

   • From the pseudocode above, the Floyd-Warshall algorithm operates using three for loops to find the shortest distance between all pairs of vertices within a graph. Therefore, the time complexity of the Floyd-Warshall algorithm is O (n3), where ‘n’ is the number of vertices in the graph. The space complexity of the algorithm is O (n2).

   Is Floyd Warshall a good algorithm?

   • The Floyd Warshall algorithm only considers the number of nodes, hence the maximum number of edges for a directed network can be as high as n* (n-1), meaning that the overall complexity could be as high as O (n^4). As a result, the Floyd-Warshall algorithm is a better option!
