   What is Floyd Warshall algorithm?

   • The Floyd Warshall Algorithm is an all pair shortest path algorithm unlike Dijkstra and Bellman Ford which are single source shortest path algorithms. 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).

   How does Floyd-Warshall algorithm work in GIS?

   • GIS applications leverage the algorithm for analyzing spatial relationships and optimizing routes in maps. The classic Floyd-Warshall algorithm can handle graphs with negative edge weights but may produce incorrect results if the graph contains negative cycles. Variations exist to detect and handle negative cycles.

   What is the auxiliary space complexity of Floyd-Warshall algorithm?

   • With V vertices, each loop iterates V times, resulting in a time complexity of O (V3) for the worst case as well. The auxiliary space complexity of the Floyd-Warshall algorithm is O (V2), where V is the number of vertices in the graph.
