Question: In which scenario would you prefer using Dijkstra\'s algorithm over the Bellman-Ford algorithm?

Options:

Correct Answer: When the graph has non-negative weights

Solution:

Dijkstra\'s algorithm is preferred when the graph has non-negative weights, as it is more efficient in such cases compared to Bellman-Ford.

In which scenario would you prefer using Dijkstra's algorithm over the Bellman-Ford algorithm?

Step 1: Understand what Dijkstra's algorithm does. It finds the shortest path from a starting point to all other points in a graph.
Step 2: Know that Dijkstra's algorithm works best when all the weights (distances) on the edges of the graph are non-negative (zero or positive).
Step 3: Learn about Bellman-Ford algorithm. It can handle graphs with negative weights and also finds the shortest paths.
Step 4: Compare the efficiency of both algorithms. Dijkstra's algorithm is generally faster than Bellman-Ford when there are no negative weights.
Step 5: Conclude that if you have a graph with only non-negative weights, you should choose Dijkstra's algorithm for better performance.

Dijkstra's Algorithm – An algorithm used for finding the shortest paths between nodes in a graph, particularly effective for graphs with non-negative weights.
Bellman-Ford Algorithm – An algorithm that computes shortest paths from a single source vertex to all other vertices in a graph, capable of handling graphs with negative weight edges.
Graph Weights – The values assigned to edges in a graph that represent the cost or distance to traverse from one vertex to another.
