Tree (data structure) — A simple unordered tree; in this diagram, the node labeled 7 has two children, labeled 2 and 6, and one parent, labeled 2. The root node, at the top, has no parent. In computer science, a tree is a widely used data structure that emulates a… … Wikipedia
Tree worship — (dendrolatry) refers to the tendency of many societies throughout history to worship or otherwise mythologize trees. Trees have played an important role in many of the world s mythologies and religions, and have been given deep and sacred… … Wikipedia
Splay tree — A splay tree is a self balancing binary search tree with the additional property that recently accessed elements are quick to access again. It performs basic operations such as insertion, look up and removal in O(log(n)) amortized time. For many… … Wikipedia
Binary tree — Not to be confused with B tree. A simple binary tree of size 9 and height 3, with a root node whose value is 2. The above tree is unbalanced and not sorted. In computer science, a binary tree is a tree data structure in which each node has at… … Wikipedia
Radix tree — In computer science, a radix tree (also patricia trie or radix trie) is a space optimized trie data structure where each node with only one child is merged with its child. The result is that every internal node has at least two children. Unlike… … Wikipedia
Dancing tree — For the film Dancing tree, see Dancing tree (film) In computer science, a dancing tree is a tree data structure, which is similar to B+ tree. Invented by Hans Reiser, for use by the Reiser4 file system. As opposed to self balancing binary search… … Wikipedia
Hash tree — A binary hash tree In cryptography and computer science Hash trees or Merkle trees are a type of data structure[citation needed] which contains a tree of summary information about a larger piece of da … Wikipedia
Metric tree — This article is about the data structure. For the type of metric space, see Real tree. A metric tree is any tree data structure specialized to index data in metric spaces. Metric trees exploit properties of metric spaces such as the triangle… … Wikipedia
Cover tree — The cover tree is a type of data structure in computer science that is specifically designed to facilitate the speed up of a nearest neighbor search. It is a refinement of the Navigating Net data structure, and related to a variety of other data… … Wikipedia
Doubly chained tree — In computer science, a Doubly chained tree is a tree data structure in which each node has two pointers. Typically, each node has one pointer pointing to its child and one pointing at the node to its right. Then the following node will have one… … Wikipedia
