How do I choose between Dijkstra's Algorithm and Bellman-Ford for shortest paths?
Davora AI Lecturer

Use Dijkstra's algorithm with a min-heap when all edge weights are strictly non-negative (O((V + E) log V)). Choose Bellman-Ford (O(V · E)) when graphs contain negative edge weights or when you need to detect negative-weight cycles.
