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 ...)
