Has anyone of you ever implemented a Fibonacci-Heap? I did so a few years back, but it was several orders of magnitude slower than using array-based BinHeaps. Back then, I thought of it as a valua...

where is the Fibonacci Heap in STL ? and if STL do not implement Fibonacci Heap what is the best practice to implement it using existing algorithms and containers in STL ?

Are Fibonacci heaps used in practice anywhere? I've looked around on SO and found answers to related questions (see below) but nothing that actually quite answers the question. There are good imp...

Is Dijkstra faster when using Fibonacci heap than with the Binary heap? I did some experiments implementing Fibonacci heap on my own and using it in Dijkstra, I also checked the ready-to-use Fibona...

This picture from Wikipedia article has three nodes of a Fibonacci heap marked in blue . What is the purpose of some of the nodes being marked in this data structure ?

What are the real world applications of Fibonacci heaps and binary heaps? It'd be great if you could share some instance when you used it to solve a problem. Edit: Added binary heaps also. C...

I was looking at the different kind of heap data structures. The Fibonacci heap seems to have the better worst case complexity for (1) insertion, (2) deletion and (2) finding the minimum element....

The Fibonacci heap data structure has the word "Fibonacci" in its name, but nothing in the data structure seems to use Fibonacci numbers. According to the Wikipedia article: The name of Fibonacc...

I've read the Wikipedia article on Fibonacci heaps and read CLRS's description of the data structure, but they provide little intuition for why this data structure works. Why are Fibonacci heaps de...

Is there a Fibonacci heap/priority queue available for Haskell? (Or even an asymptotically better one?) I found a list of various priority queue implementations in this question, but I couldn't fin...

I need to use Fibonacci heap in my project and I am trying to use it from boost library. But I cannot figure out how to set up a user defined compare function for arbitrary data type. I need to con...

I'm learning f-heap from 'introduction to algorithms', and the 'decrease-key' operation really confuses me -- why does this need a 'cascading-cut' ? if this operation is removed: the cost of mak...

I recently made an initial comparison of the running time of Dijkstra's algorithm using two data structures, the Java-based PriorityQueue (based on a binary heap, if I'm not mistaken), and a Fibona...

I'm in a beginner level computer programming class and I (along with 3 other students) want to implement a Fibonacci heap for a final project. Can anyone suggest some good applications of fibonacci...

I am interested in implementing a priority queue to enable an efficient Astar implementation that is also relatively simple (the priority queue is simple I mean). It seems that because a Skip Lis...

I know Prim's algorithm and I know its implementation but always I skip a part that I want to ask now. It was written that Prim's algorithm implementation with Fibonacci heap is O(E + V log(V)) and...
