## Does Bellman-Ford algorithm work on undirected graph?

The Bellman-Ford algorithm works on directed graphs. To make it work with undirected graphs we must make each undirected edge into two directed edges (one in each direction) with the same weights as the original undirected edge.

## Is Bellman Ford directed graph?

Bellman-Ford algorithm is designed for directed graphs. initialization At the end, d[v] = δ(s, v).

**Does Floyd warshall work for undirected graphs?**

No it can’t. The Floyd–Warshall algorithm can be used to find the shortest cycle if and only if the graph is directed. For directed graphs the method is as Melissa explained (setting ). But it cannot be used in undirected graphs.

**Can Dijkstra be used for undirected graphs?**

You can use Dijkstra’s algorithm in both directed and undirected graphs, because you simply add edges nodes into the PriorityQueue when you have an edge to travel to from your adjacency list.

### What is routing algorithm describe Bellman-Ford algorithm?

The Bellman–Ford algorithm is an algorithm that computes shortest paths from a single source vertex to all of the other vertices in a weighted digraph. In such a case, the Bellman–Ford algorithm can detect and report the negative cycle.

### Where is Bellman Ford algorithm used?

Bellman-Ford algorithm is used to find the shortest path from the source vertex to every vertex in a weighted graph. Unlike Dijkstra’s algorithm, the bellman ford algorithm can also find the shortest distance to every vertex in the weighted graph even with the negative edges.

**What strategy is used in the Floyd-Warshall algorithm?**

Dynamic Programming

The strategy adopted by the Floyd-Warshall algorithm is Dynamic Programming. The running time of the Floyd-Warshall algorithm is determined by the triply nested for loops of lines 3-6. Each execution of line 6 takes O (1) time. The algorithm thus runs in time θ(n3 ).
