  2. Baum test - Wikipedia

    en.wikipedia.org/wiki/Baum_test

    The first step is to let the participant draw a tree on a paper. In some cases, participants are also asked to write a short essay about the drawn tree. [7] A psychologist or a psychiatrist will then evaluate the various aspects of the drawing as well as the individual's behavior or comments while completing the test. The evaluation is based on ...

  3. Tree structure - Wikipedia

    en.wikipedia.org/wiki/Tree_structure

    Tree structures can depict all kinds of taxonomic knowledge, such as family trees, the biological evolutionary tree, the evolutionary tree of a language family, the grammatical structure of a language (a key example being S → NP VP, meaning a sentence is a noun phrase and a verb phrase, with each in turn having other components which have ...

  5. R-tree - Wikipedia

    en.wikipedia.org/wiki/R-tree

    The key idea is to use the bounding boxes to decide whether or not to search inside a subtree. In this way, most of the nodes in the tree are never read during a search. Like B-trees, R-trees are suitable for large data sets and databases, where nodes can be paged to memory when needed, and the whole tree cannot be kept in main memory. Even if ...

  6. 2–3–4 tree - Wikipedia

    en.wikipedia.org/wiki/2–3–4_tree

    In computer science, a 2–3–4 tree (also called a 2–4 tree) is a self-balancing data structure that can be used to implement dictionaries.The numbers mean a tree where every node with children (internal node) has either two, three, or four child nodes:

  7. AVL tree - Wikipedia

    en.wikipedia.org/wiki/AVL_tree

    To split an AVL tree into two smaller trees, those smaller than key k, and those greater than key k, first draw a path from the root by inserting k into the AVL. After this insertion, all values less than k will be found on the left of the path, and all values greater than k will be found on the right.

  8. Binary tree - Wikipedia

    en.wikipedia.org/wiki/Binary_tree

    Here the trees have no values attached to their nodes (this would just multiply the number of possible trees by an easily determined factor), and trees are distinguished only by their structure; however, the left and right child of any node are distinguished (if they are different trees, then interchanging them will produce a tree distinct from ...

  9. Tree line - Wikipedia

    en.wikipedia.org/wiki/Tree_line

    The foreground shows the transition from trees to no trees. These trees are stunted in growth and one-sided because of cold and constant wind. The tree line is the edge of a habitat at which trees are capable of growing and beyond which they are not. It is found at high elevations and high latitudes. Beyond the tree line, trees cannot tolerate ...
