  PlanetMath: internal node (of a tree)
An internal node of a tree is any node which has degree greater than one.
Or, phrased in rooted tree terminology, the internal nodes of a tree are the nodes which have at least one child node.
This is version 3 of internal node (of a tree), born on 2002-03-02, modified 2002-03-03.

 Binary Search
is the length of the path from the root to external node j.
Then the internal path length I increases by an amount e, the external path length increases by an amount e+2 (why??), and the number of nodes in the tree increases by 2 - the two new external nodes, each having a path length of e+1.
Still, since we have a linked structure, once we determine where a node is to be inserted or deleted (we do this with treesearch), it is a simple matter to link in a new node, or to remove the links for a deletion.

 Root node - Wikipedia, the free encyclopedia
A root node is a specially chosen node in a tree data structure at which all operations on the tree begin.
It is not the child of any other node, and all other nodes can be reached from it by following edges or links.
Every node in a tree can be seen as the root node of the subtree rooted at that node.

 GNU libavl 2.0.1
Formally, a binary tree is either an "external node" or an "internal node" connected to a pair of binary trees called the internal node's left subtree and right subtree.
Every internal node always has exactly two children, although those children may be external nodes, so we must also revise definitions that depend on a node's number of children.
Then, a "leaf" is an internal node with two external node children and a "nonterminal node" is an internal node at least one of whose children is an internal node.

 Internal Mammary Node Drainage and its Role in Sentinel Lymph Node Biopsy: The Initial ALMANAC Experience   (Site not responding. Last check: 2007-10-03)
The practicability and relevance of internal mammary SLN biopsy as a method to improve nodal staging and treatment in breast cancer were investigated.
Lymphoscintigraphy showed internal mammary sentinel nodes in 62 patients (9%), and internal mammary drainage was identified perioperatively in an additional 7 patients (1%) using γ probe detection.
Sampling of the internal mammary basin, based on the results of lymphoscintigraphy and γ probe detection, was done in 31 of 69 patients (45%).

 System Management
Because the internal nodes are not directly connected to the outside, they can use certain reserved IP addresses used for local networks.
For example, the worldly node could be assigned an IP address of 192.168.1.1 and each internal node would be sequentially numbered from 192.168.1.2 to 192.168.1.16.
After configuring the internal node, you ned to make an archive of each disk partition, omitting /proc, which is not a physiscal disk partition.

In this example, however, no node is being modified (the root handle in the Bintree object is modified to reflect an empty tree node at the root).] =========================== insert 25 25 Christiansburg =========================== City Christiansburg successfully inserted at position 25 25.
Empty leaf nodes are not stored explicitly in the tree (they are recognized by their handle value).
The way I think of doing it, the nodes in the tree are actually on disk in the order CGGGB where C is the node for Christiansburg, B is the node for Blacksburg, and G are the internal nodes.

 CISC 320 Lecture Notes for Class No. 10, Feb 27, 2002
Draw a diagram (similar to ones drawn in lecture) that shows the unique paths assigned to each internal node as is done in the proof of theorem 2.12.
The bottom up construction is applied only to the n internal nodes of the heap data structure (actually, it needs to be applied only to the top-most n/2 nodes, an important obervation in an actual implementation, but not important to this argument).
This property of the number of nodes decreasing by a large factor, like 1/2, when the work to process them only increases by a constant amount is usually an indication of a fast algorithm.

 Unsuccessful Search
The preceding analysis shows that the average number of nodes visited during a successful search depends on the internal path length  , which is simply the sum of the depths of all the internal nodes.
Similarly, the average number of nodes visited during an unsuccessful search depends on the external path length  , which is the sum of the depths of all the external nodes.
Since the difference between the internal and external path lengths of any tree with n internal nodes is 2n, then we can say the same thing about the average internal and external path lengths averaged over all search trees.

 Digital gate definition language
Resources available to a GDL program are pins, notated as in "#3"; internal nodes, notated as in "##6"; and state variables, such as "A", "P", or "V26".
A pin or internal node is a true LOG node; it uses a five-valued logic (One, Zero, undriven or "None", and weak One and Zero) and must be assigned to once per time-step.
RISE p The result is One if the specified node is receiving a rising transition, that is, the previous time-step drove the pin to a One, but the time-step before that drove it to a Zero.

One interesting property of full m-ary trees is that you can write a formula relating the number of internal nodes i, the number of leaf nodes l, and the total number of nodes n (obviously, n = i + l).
Definition: a binary search tree is a binary tree such that at each internal node, v, the value stored at v is greater than (or equal) any value stored in v's left subtree and is less than (or equal) any value stored in v's right subtree.
At each node in an AVL tree the difference in height between the left subtree and the right subtree is guaranteed to be -1, 0 or 1.

 2. Weight-Biased Leftist Trees
The weight, w(x), of any node x is the number of internal nodes in the subtree with root x.
Each node of a min-WBLT has the fields: lsize (number of internal nodes in left subtree), rsize, left (pointer to left subtree), right, and data.
While the number of size fields in a node may be reduced to one, two fields result in a faster implementation.

Since the next node has 3 entries, its rightmost (first) entry 46 can replace 43 in both the leaf and internal nodes, leading to the following tree:  Next, we delete 18, which is a rightmost entry in a leaf node and hence appears in an internal node of the B + -tree.
This is normally done by moving 56 up to replace 60 in the internal node, but since this leads to underflow in the node that used to contain 56, the nodes can be reorganized as follows:  Finally, removing 37 causes serious underflow, leding to a reorganization of the whole tree.
One approach to deleting the value in the root node is to use the rightmost value in the next leaf node (the first leaf node in the right subtree) to replace the root, and move this leaf node to the left subtree.

 COS 435, Spring 2002: Problem Sets
If all internal nodes are at capacity, we will still need a tree of height 2 since we can get at most 616 leaves in a tree of height one.
For the internal nodes, we need not store entire index terms, but rather just the minimal prefix of each term that distinguishes the index terms in subtree to the left from those in the subtree to the right.
In its simplest form, each index term except the first in a sequence of terms for a node is represented as a difference from the preceding term in the sequence.

A binary tree is made up of a finite set of nodes that is either empty or consists of a node called the root together with two binary trees, called the left and right subtrees, which are disjoint from each other and from the root.
Full binary tree: each node either is a leaf or is an internal node with exactly two non­empty children.
All elements stored in the right subtree of a node whose value is K have values greater than or equal to K.

 (WO 02/30134) DISTRIBUTED ADMISSION CONTROL   (Site not responding. Last check: 2007-10-03)
(57) A mobile communications system has a radio network controller (18a, 18b) and a Node B (20a, 20b, 20c, 20d) coupled to the radio network controller (18a, 18b), the Node B (20a, 20b, 20c, 20d) being operable to control a plurality of its Node B internal resources for admission control.
Admission control is moved from a controlling radio network controller (CRNC) (44) to the Node B (20a, 20b, 20c, 20d) so as to avoid possible errors relating to fragmentation that occur in systems in which the CRNC (44) controls admission.
To support network related requirements, such as reserving capacity for high priority calls and incoming handovers, the CRNC (44) informs the Node B (20a, 20b, 20c, 20d) about the reservations that shall be applied, and the Node B configures the admission control algorithm in accordance with the reservations.
