Fibonacci heap

(data structure)

Definition: A heap made of a forest of trees. The amortized cost of the operations create, insert a value, decrease a value, find minimum, and merge or join (meld) two heaps, is a constant Θ(1). The delete operation takes O(log n).

Generalization (I am a kind of ...)

Aggregate parent (I am a part of or used in ...)
priority queue, Dijkstra's algorithm.

Note: After [CLR90, page 421].
