What is the time complexity of Dijkstra's algorithm?
Dijkstra's algorithm has a time complexity of O(V^2) using a simple array, but it can be improved to O(E + V log V) with a priority queue.
How does the complexity of BFS compare to DFS?
Both BFS and DFS have a time complexity of O(V + E), but their space complexity differs: BFS uses O(V) while DFS uses O(h), where h is the maximum depth.
What factors affect the performance of graph algorithms?
Performance can be affected by the graph's density, the data structure used for representation, and the specific algorithm's design.
Can you explain the complexity of the Floyd-Warshall algorithm?
The Floyd-Warshall algorithm has a time complexity of O(V^3) and is used for finding shortest paths between all pairs of vertices.
