  2. Tree traversal - Wikipedia

    en.wikipedia.org/wiki/Tree_traversal

    In computer science, tree traversal (also known as tree search and walking the tree) is a form of graph traversal and refers to the process of visiting (e.g. retrieving, updating, or deleting) each node in a tree data structure, exactly once. Such traversals are classified by the order in which the nodes are visited.

  3. Longest common substring - Wikipedia

    en.wikipedia.org/wiki/Longest_common_substring

    One can find the lengths and starting positions of the longest common substrings of and in (+) time with the help of a generalized suffix tree. A faster algorithm can be achieved in the word RAM model of computation if the size σ {\displaystyle \sigma } of the input alphabet is in 2 o ( log ⁡ ( n + m ) ) {\displaystyle 2^{o\left({\sqrt {\log ...

  4. Top tree - Wikipedia

    en.wikipedia.org/wiki/Top_Tree

    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.

  6. Dichotomic search - Wikipedia

    en.wikipedia.org/wiki/Dichotomic_search

    Abstractly, a dichotomic search can be viewed as following edges of an implicit binary tree structure until it reaches a leaf (a goal or final state). This creates a theoretical tradeoff between the number of possible states and the running time: given k comparisons, the algorithm can only reach O(2 k ) possible states and/or possible goals.

  7. LCP array - Wikipedia

    en.wikipedia.org/wiki/LCP_array

    Augmenting the suffix array with the LCP array allows one to efficiently simulate top-down and bottom-up traversals of the suffix tree, [1] [2] speeds up pattern matching on the suffix array [3] and is a prerequisite for compressed suffix trees.

  8. k-d tree - Wikipedia

    en.wikipedia.org/wiki/K-d_tree

    implicit k-d tree, a k-d tree defined by an implicit splitting function rather than an explicitly-stored set of splits; min/max k-d tree, a k-d tree that associates a minimum and maximum value with each of its nodes; Relaxed k-d tree, a k-d tree such that the discriminants in each node are arbitrary; Related variations:

  9. Binary tree - Wikipedia

    en.wikipedia.org/wiki/Binary_tree

    A tree whose root node has two subtrees, both of which are full binary trees. A perfect binary tree is a binary tree in which all interior nodes have two children and all leaves have the same depth or same level (the level of a node defined as the number of edges or links from the root node to a node). [18] A perfect binary tree is a full ...
