Example of a binary max-heap with node keys being integers between 1 and 100. In computer science, a heap is a tree-based data structure that satisfies the heap property: In a max heap, for any given node C, if P is the parent node of C, then the key (the value) of P is greater than or equal to the key of C.
Example of a complete binary max-heap Example of a complete binary min heap. A binary heap is a heap data structure that takes the form of a binary tree. Binary heaps are a common way of implementing priority queues. [1]: 162–163 The binary heap was introduced by J. W. J. Williams in 1964 as a data structure for implementing heapsort. [2]
A skew heap (or self-adjusting heap) is a heap data structure implemented as a binary tree. Skew heaps are advantageous because of their ability to merge more quickly than binary heaps. In contrast with binary heaps, there are no structural constraints, so there is no guarantee that the height of the tree is logarithmic. Only two conditions ...
A heap is a tree data structure with ordered nodes where the min (or max) value is the root of the tree and all children are less than (or greater than) their parent nodes. Pages in category "Heaps (data structures)"
Heap (data structure), a data structure commonly used to implement a priority queue; Heap (mathematics), a generalization of a group; Heap (programming) (or free store), an area of memory for dynamic memory allocation; Heapsort, a comparison-based sorting algorithm; Heap overflow, a type of buffer overflow that occurs in the heap data area
In detail, a b-heap can be implemented in the following way. Poul-Henning Kamp [4] gives two options for the layout of the nodes: one in which two positions per page are wasted, but the strict binary structure of the tree is preserved, and another which uses the whole available space of the pages, but has the tree fail to expand for one level upon entering a new page (The nodes on that level ...

He worked with Donald E. Knuth to develop a two-heap data structure that they called a "priority deque", published as an exercise in The Art of Computer Programming in 1973. [18] [19] After moving to Canada in 1974, he worked for Bell-Northern Research Ltd., Ottawa (BNR) and Northern Telecom (Nortel) until retiring in 1995.
