What are some common graph algorithms?
Some common graph algorithms include Dijkstra's algorithm, A* search, and Depth-First Search (DFS). Would you like to know more about any specific one?
Can you explain Dijkstra's algorithm?
Dijkstra's algorithm finds the shortest path from a starting node to all other nodes in a weighted graph. It uses a priority queue to explore the nearest unvisited node.
What is the time complexity of Dijkstra's algorithm?
The time complexity of Dijkstra's algorithm is O(V^2) with a simple implementation, but it can be improved to O(E + V log V) using a priority queue.
Are there any limitations to Dijkstra's algorithm?
Yes, Dijkstra's algorithm doesn't work with graphs that have negative weight edges. For such cases, the Bellman-Ford algorithm is a better choice.
