FAQs

Question: What is the main advantage of using Dijkstra's algorithm?
Answer: The main advantage of Dijkstra's algorithm is its efficiency in finding the shortest path in graphs with non-negative weights.

Question: Can Dijkstra's algorithm be used for negative weight edges?
Answer: No, Dijkstra's algorithm cannot handle graphs with negative weight edges; for such cases, the Bellman-Ford algorithm is preferred.
