Question: If a graph has negative weight edges, which algorithm should be used instead of Dijkstra\'s algorithm?

Options:

Correct Answer: Bellman-Ford algorithm

Solution:

The Bellman-Ford algorithm should be used instead of Dijkstra\'s algorithm when the graph has negative weight edges, as it can handle such cases.

If a graph has negative weight edges, which algorithm should be used instead of Dijkstra's algorithm?

If a graph has negative weight edges, which algorithm should be used instead of Dijkstra's algorithm?

Step 1: Understand that Dijkstra's algorithm is used to find the shortest path in a graph with non-negative edge weights.
Step 2: Recognize that if a graph has edges with negative weights, Dijkstra's algorithm may not work correctly.
Step 3: Learn about the Bellman-Ford algorithm, which is designed to handle graphs with negative weight edges.
Step 4: Conclude that when dealing with negative weight edges, you should use the Bellman-Ford algorithm instead of Dijkstra's algorithm.
