  2. Structure chart - Wikipedia

    en.wikipedia.org/wiki/Structure_Chart

    A process flow diagram describing the construction of a structure chart by a so-called Subject Matter Experts (SME). [2]According to Wolber (2009), "a structure chart can be developed starting with the creating of a structure, which places the root of an upside-down tree which forms the structure chart.

  3. Behavior tree (artificial intelligence, robotics and control)

    en.wikipedia.org/wiki/Behavior_tree_(artificial...

    The execution of a behavior tree starts from the root which sends ticks with a certain frequency to its child. A tick is an enabling signal that allows the execution of a child. When the execution of a node in the behavior tree is allowed, it returns to the parent a status running if its execution has not finished yet, success if it has ...

  4. Computational phylogenetics - Wikipedia

    en.wikipedia.org/wiki/Computational_phylogenetics

    Phylogenetic trees generated by computational phylogenetics can be either rooted or unrooted depending on the input data and the algorithm used. A rooted tree is a directed graph that explicitly identifies a most recent common ancestor (MRCA), [citation needed] usually an inputed sequence that is not represented in the input.

  5. 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.

  6. Treehouse (company) - Wikipedia

    en.wikipedia.org/wiki/Treehouse_(company)

    Treehouse or (Teamtreehouse) is an online technology school that offers beginner to advanced courses in web design, web development, mobile development and game development. [3] Its courses are aimed at beginners looking to learn computer coding skills for a career in the tech industry.

  7. Huffman coding - Wikipedia

    en.wikipedia.org/wiki/Huffman_coding

    In computer science and information theory, a Huffman code is a particular type of optimal prefix code that is commonly used for lossless data compression.The process of finding or using such a code is Huffman coding, an algorithm developed by David A. Huffman while he was a Sc.D. student at MIT, and published in the 1952 paper "A Method for the Construction of Minimum-Redundancy Codes".

  8. Polar code (coding theory) - Wikipedia

    en.wikipedia.org/wiki/Polar_code_(coding_theory)

    Fano decoding is a tree search algorithm that determines the transmitted codeword by utilizing an optimal metric function to efficiently guide the search process. [10] PAC codes are also equivalent to post-transforming polar codes with certain cyclic codes. [11]

  9. Jackson structured programming - Wikipedia

    en.wikipedia.org/wiki/Jackson_Structured_Programming

    Note that it in the above diagrams, it is element A that is the sequence or iteration, not the elements B, C or D (which in the above diagrams are all elementary). Jackson gives the 'Look-down rule' to determine what an element is, i.e. look at the elements below an element to find out what it is.
