In a fibonacci heap, a node can have more than two children or no children at all. Also, it has more efficient heap operations than that supported by the binomial and binary heaps. The fibonacci heap is called afibonacciheap because the trees are constructed in a way such that a tree of...
Mergeable heaps A mergeable heap is any data structure that supports the following five operations, in which each element has a key: MAKE-HEAP./ creates and returns a new heap containing no elements. INSERT.H; x/ inserts element x, whose key has already been filled in, into heap H. MI...
The Fibonacci heap is a classic data structure that supports deletions in logarithmic amortized time and all other heap operations in O(1) amortized time. We explore the design space of this data structure. We propose a version with the following improvements over the original: (i) Each heap ...
fibheap is small and simple Fibonacci Heap implementation, written in Go. It can be utilized as a min or max heap, depending on the implementation of the Item.Less method. Fibonacci heaps are a type of heap data structure that provide faster insertion and deletion operations compared to binary...
The present application relates to Fibonacci heaps and, in particular to a specialized Fibonacci heap concept that is suited for application to Internet link-state protocols that use a Dijkstra-like algorithm to determine shortest paths through a portion of a computer network. ...

Karger proposed a simple randomized variant of Fibonacci heaps in which mark bits are replaced by coin flips. This variant still has expected amortized cost O(1) for insert, decrease-key, and merge. Karger conjectured that this data structure has expected amortized cost O(log s) for delete-...
This note describes a data structure that has the same theoretical performance as Fibonacci heaps, supporting decrease-key operations in O (1) amortized time and delete-min operations in O (log n ) amortized time. The data structure is simple to explain and analyze, and may be of pedagogical...
Our structure, Fibonacci heaps (abbreviated F-heaps), extends the binomial queues proposed by Vuillemin and studied further by Brown. F-heaps support arbitrary deletion from an n-item heap in 0(log n) amortized time and all other standard heap operations in 0(1) amortized time. Using F-...
Data structuresPriority queuesFibonacci heapsamortized analysis decrease keyWe give a priority queue that achieves the same amortized bounds as Fibonacci heaps. Namely, find-min requires O(1) worst-case time, insert, meld and decrease-key require O(1) amortized time, and delete-min requires O(...
