Dijkstra and Shortest Path Algorithms - Applications - Case Studies

Q. In a case study involving a city map, which application of Dijkstra's algorithm is most relevant?

Solution

In a city map scenario, Dijkstra's algorithm is most relevant for finding the fastest route between two locations.

Correct Answer: A — Finding the fastest route between two locations

Q. What is the main advantage of using Dijkstra's algorithm over other shortest path algorithms?

Solution

The main advantage of Dijkstra's algorithm is that it guarantees the shortest path in graphs with non-negative weights.

Correct Answer: C — It guarantees the shortest path in graphs with non-negative weights

Q. Which of the following is NOT a limitation of Dijkstra's algorithm?

Solution

Dijkstra's algorithm is designed to find the shortest path from a single source to all other nodes, which is one of its primary functions.

Correct Answer: C — It finds the shortest path from a single source

Q. Which of the following scenarios would require the use of an alternative to Dijkstra's algorithm?

Solution

If the graph contains negative weight edges, an alternative algorithm like Bellman-Ford should be used instead of Dijkstra's.

Correct Answer: B — Calculating the shortest path in a graph with negative weights
