WebBellman-Ford algorithm is a single-source shortest path algorithm, which allows for negative edge weight and can detect negative cycles in a graph. Dijkstra algorithm is also another single-source shortest path algorithm. However, the weight of all the edges must be non-negative. WebNov 24, 2024 · The Bellman-Ford algorithm is a single-source shortest path algorithm. This means that, given a weighted graph, this algorithm will output the shortest distance from a selected node to all other nodes. It is very similar to the Dijkstra Algorithm.
