WebUniversity of Limerick. Dijkstra’s algorithm finds the shortest path between a single pair of nodes, while Floyd-Warshall finds the shortest paths between all pairs of nodes. Of course, you can ... WebWe know we can compute APSP by running Dijkstra’s algorithm on each node v2V and obtain a total runtime of O(mn+ n2 logn). The runtime of the Floyd-Warshall algorithm, on the other hand, is O(n3). We know that in the worst case m= O(n2), and thus, the Floyd-Warshall algorithm can be at least as bad as running Dijkstra’s algorithm ntimes!

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).

WebJun 2, 2016 · It is important to note that in this analysis, the implementation of Dijkstra's algorithm will use a Fibonacci heap as its minimum priority queue, as it is the most efficient structure for the algorithm. Though, even using a simple minimum heap will yield a faster result than Floyd-Warshall.
