	Tree data structure - Wikipedia, the free encyclopedia
		In graph theory, a tree is a connected acyclic graph.
		Binary search trees are one kind of ordered tree, and there is a one-to-one mapping between binary trees and general ordered trees.
		There are many different ways to represent trees; common representations represent the nodes as records allocated on the heap with pointers to their children, their parents, or both, or as items in an array, with relationships between them determined by their positions in the array (e.g., binary heap).

	Binary tree - Wikipedia, the free encyclopedia
		The height of a node n is the length of the path from the node n to its furthest leaf.
		In-order traversal is useful in binary search trees, where this traversal visits the nodes in increasing order.
		There is a one-to-one mapping between general ordered trees and binary trees, which in particular is used by Lisp to represent general ordered trees as binary trees.

	Station Information - Graph theory
		Structures that can be represented as graphs are ubiquitous, and many problems of practical interest can be formulated as questions about certain graphs.
		Every graph gives rise to a matroid, but in general the graph cannot be recovered from its matroid, so matroids are not truly generalizations of graphs.

	trie (Site not responding. Last check: 2007-09-19)
		In computer science, a trie (from "retrieval", usually pronounced like the word "try") is an ordered tree data structure that is used to store an associative array where the keys are stringss.
		Unlike a binary search tree, no node in the tree stores the key associated with that node; instead, its position in the tree shows what key it is associated with.
		Although it seems restrictive to say a trie's key type must be a string, many common data types can be seen as strings; for example, an integer can be seen as a string of bits.

	Elementary Patterns: Linear Indexed Data Structure
		The order of the elements in the collection is important but elements will not be added to the collection in order and their location in the final order is dependent on the other objects in the collection.
		In many languages, such as C, C++, and Java, valid indices for a structure with N elements ranges from 0 to N-1, where 0 is the index of the 1st element in the Linear Indexed Data Structure and N-1 is the index of the last element.
		Thus, it is possible with these data structures to have an index that is valid as far as the language and the specification of the data structure is concerned, but refers to an element that never had meaningful data assigned to it.

	VDM Specification of an Ordered Binary Tree
		A binary tree is a recursive data structure in the sense that the structure consists of either an ``empty'' root node or a root node that has a value together with two further ``branches'' (left and right) which are themselves further instances of the same data structure.
		In VDM, we can specify such a data structure using a composite which is recursively defined, with an extension of a type definiton method introduced in Chapter 3.
		The invariant then states that all natural numbers n that belong to the set of node values returned from the left subtree of the tree with ``val'' as the root must be less than val, and all the numbers returned from the right subtree must be greater than val.

		Trees provide both these characteristics, and are also one of the most interesting data structures.
		The two children of each node in a binary tree are called the "left child" and the "right child", corresponding to their position when you draw a picture of a tree.
		A node in a binary tree doesn't necessarily have the maximum of two children; it may have only a left child, or only a right child, or it can have no children at all (in which case it's a leaf).

		In computer science, a trie is an ordered tree data structure that is used to store an associative array where the keys are strings.
		Due to its etymology some sources say it should be pronounced as "tree", while others encourage the use of "try" in order to distinguish it from the more general tree.
		A trie can be seen as a deterministic finite automaton, although the symbol on each edge is often implicit in the order of the branches.

	XSL Transformations (XSLT)
		For simple transformations where the structure of the result tree is independent of the structure of the source tree, a stylesheet can often consist of only a single template, which functions as a template for the complete result tree.
		When the source tree is created by parsing a well-formed XML document, the root node of the source tree will automatically satisfy the normal restrictions of having no text node children and exactly one element child.
		If a newline occurring in an attribute value in the tree were output as a newline character rather than as character reference, then the attribute value in the tree created by reparsing the XML would contain a space not a newline, which would mean that the tree had not been output correctly.

	Techquila - Conclusions
		In practice, we believe that the real reasons for choosing one API over another are not so much the size and representational complexity issues as they are an issue of having a basic data model suitable for the representation of a topic map and convergence with XTM syntax to flatten the learning curve.
		As explained in the analysis for that model, API-1 is not really suitable for representing a topic map as it is based on an programming model originally developed for the representation of an ordered tree data structure rather than the graph structure of a topic map.
		A further practical consideration in the evaluation of these APIs for the development of a common topic map API is that a number of implementations of topic map APIs are already developed and deployed.

		In the shown example, keys are listed in the nodes and values below them.
		Looking up a key of length m takes only O(m) time; in the worst case in a BST, O(m²) time is required, because initial characters are examined repeatedly during multiple comparisons.
		This saves space in maps where long paths down the trie do not have branches fanning out, for example in maps where many keys have a long common prefix or where many portions of keys are composed of characters all unique.
