What are the applications of Fibonacci heaps?

Fibonacci heaps are primarily used in network optimization algorithms, like Dijkstra's and Prim's algorithms, due to their efficient decrease-key operation.

Can you explain how they improve the performance of Dijkstra's algorithm?

Sure! Fibonacci heaps allow for a more efficient decrease-key operation, which reduces the overall time complexity of Dijkstra's algorithm to O(E + V log V), where E is the number of edges and V is the number of vertices.

Are there any other algorithms that benefit from Fibonacci heaps?

Yes, they are also beneficial in the implementation of the minimum spanning tree algorithms, such as Prim's algorithm, and in various graph algorithms that require priority queues.

What are the limitations of using Fibonacci heaps?

While Fibonacci heaps offer theoretical advantages, they have higher constant factors and are more complex to implement than simpler heap structures like binary heaps.
