Question

Which of the following shortest path algorithm cannot detect presence of negative weight cycle graph?
1) Bellman Ford Algorithm
2) Dijsktra's Algorithm
3) Floyd- Warshall Algorithm
4) None of the above

Answer 1

Answer:- Option B.........

Answer 2

Option (B)

The shortest path algorithm cannot detect the presence of a negative weight cycle graph Dijkstra's Algorithm.

Dijkstra's Algorithm:

• The algorithm can take on a variety of forms. The original Dijkstra algorithm found the shortest path between two nodes.
• However, a more common variant chooses a single node as the "source" node and searches for the shortest paths between it and all other nodes in the network, yielding a shortest-path tree.
• The approach determines the shortest path between a specified source node and the remaining nodes in the graph.
• It can also be used to find the shortest paths between a single node and a single destination node, with the process finishing once the shortest path between the target node and the destination node has been found.
