WebNov 17, 2024 · 3. Bellman-Ford Algorithm. As with Dijkstra’s algorithm, the Bellman-Ford algorithm is one of the SSSP algorithms. Therefore, it calculates the shortest path from a starting source node to all the nodes inside a weighted graph. However, the concept behind the Bellman-Ford algorithm is different from Dijkstra’s. 3.1. WebIn my data structures class we covered two minimum spanning tree algorithms (Prim's and Kruskal's) and one shortest path algorithm (Dijkstra's). Minimum spanning tree is a tree in a graph that spans all the vertices and total weight of a tree is minimal. Shortest path is quite obvious, it is a shortest path from one vertex to another.
