Floyd-Warshall
Floyd-Warshall finds the shortest paths between all pairs of vertices in a weighted graph using dynamic programming. It works with both positive and negative edge weights but not negative cycles. It is ideal when you need shortest paths between every pair of nodes simultaneously.
Use Cases
- •All-pairs shortest path computation
- •Transitive closure of a graph
- •Detecting negative cycles in a weighted graph
