What is the complexity of shortest path algorithms?

What is the complexity of shortest path algorithms?

The complexity of shortest path algorithms varies. For example, Dijkstra's algorithm has a time complexity of O(V^2) with a simple array, but can be improved to O(E + V log V) using a priority queue.

What factors affect the performance of these algorithms?

Factors include the graph's density, the number of vertices and edges, and the data structure used for the priority queue.

Are there any algorithms that perform better in specific scenarios?

Yes, for example, A* algorithm is more efficient in pathfinding on maps due to its heuristic approach.

Can you explain the difference between Dijkstra's and A* algorithms?

Dijkstra's algorithm finds the shortest path without any heuristics, while A* uses heuristics to guide its search, making it faster in many cases.
