A vantage-point tree (or VP tree) is a metric tree that segregates data in a metric space by choosing a position in the space (the "vantage point") and partitioning the data points into two parts: those points that are nearer to the vantage point than a threshold, and those points that are not. By recursively applying this procedure to ...
Radix tree. In computer science, a radix tree (also radix trie or compact prefix tree or compressed trie) is a data structure that represents a space-optimized trie (prefix tree) in which each node that is the only child is merged with its parent. The result is that the number of children of every internal node is at most the radix r of the ...
A top tree is a data structure based on a binary tree for unrooted dynamic trees that is used mainly for various path-related operations. It allows simple divide-and-conquer algorithms. It has since been augmented to maintain dynamically various properties of a tree such as diameter, center and median. A top tree is defined for an underlying ...
I feel tree structure and hierarchical tree structure are the more obvious candidates, as they both describe their subject in similar terms, whereas tree data structure adds 'data' to the equation. But I know too little about the use of tree structures in communications and computer science to decide whether these are three distinct articles.
Formally, a purely functional data structure is a data structure which can be implemented in a purely functional language, such as Haskell. In practice, it means that the data structures must be built using only persistent data structures such as tuples, sum types, product types, and basic types such as integers, characters, strings.
Fusion tree. In computer science, a fusion tree is a type of tree data structure that implements an associative array on w -bit integers on a finite universe, where each of the input integers has size less than 2 w and is non-negative. When operating on a collection of n key–value pairs, it uses O(n) space and performs searches in O(logw n ...
An octree is a tree data structure in which each internal node has exactly eight children. Octrees are most often used to partition a three-dimensional space by recursively subdividing it into eight octants. Octrees are the three-dimensional analog of quadtrees. The word is derived from oct (Greek root meaning "eight") + tree.
