• Binary search tree — In computer science, a binary search tree (BST) is a binary tree data structurewhich has the following properties: *each node (item in the tree) has a value; *a total order (linear order) is defined on these values; *the left subtree of a node… …   Wikipedia

• Self-balancing binary search tree — In computer science, a self balancing binary search tree or height balanced binary search tree is a binary search tree that attempts to keep its height , or the number of levels of nodes beneath the root, as small as possible at all times,… …   Wikipedia

• Randomized binary search tree — A randomized binary search tree (abbreviated RBST, also known as Cartesian tree) is a type of binary search tree, with data nodes organizedas in a normal binary search tree. Each node has also an access priority, namely p(n) which is chosen in a… …   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

• Search algorithm — In computer science, a search algorithm, broadly speaking, is an algorithm that takes a problem as input and returns a solution to the problem, usually after evaluating a number of possible solutions. Most of the algorithms studied by computer… …   Wikipedia

• Ternary search tree — In computer science, a ternary search tree (trie,TST) is a ternary (three way) tree data structure which combines the time efficiency of digital tries with the space efficiency of binary search trees. The resulting structure is faster than… …   Wikipedia

• Threaded binary tree — A threaded binary tree may be defined as follows:A binary tree is threaded by making all right child pointers that would normally be null point to the inorder successor of the node, and all left child pointers that would normally be null point to …   Wikipedia

• Top Trees — The Top Tree is a binary tree based data structure for unrooted dynamic trees which is used mainly for carrying out various path related operations, it allows simple Divide and conquer algorithms. It has since been augmented to maintain… …   Wikipedia
