Bellman-ford
The Bellman–Ford algorithm computes single-source shortest paths in a weighted digraph
Floyd-warshall
The Floyd-Warshall algorithm is an O(|V|^3) algorithm for computing all-pairs shortest paths in a directed weighted graph.

Because bellman-ford runs in time o mn the overall asymptotic runtime is still o mn + n 2 log n so if m o n 2 note that this is little-o of n this approach is asymptotically faster than using floyd-warshall from question Dijkstra vs. Floyd-Warshall: Finding optimal route on all node pairs |
