The AVL tree is named after its two Soviet inventors, G. M. Adelson-Velskii and E. M. Landis, who published it in their 1962 paper " An algorithm for the organization of information.

AVL and tree
In computer science, an AVL tree is a self-balancing binary search tree, and it was the first such data structure to be invented.
In other words AVL tree is a binary search tree where the height of the left subtree differs from the height of the right subtree by at most 1 level, if it exceeds 1 level then rebalancing occurs.
Basic operations of an AVL tree involve carrying out the same actions as would be carried out on an unbalanced binary search tree, but modifications are preceded or followed by one or more operations called tree rotations, which help to restore the height balance of the subtrees.
Tree rotations are used in a number of tree data structures such as AVL trees, red-black trees, splay trees, and treaps.
* AVL tree, red-black tree, and splay tree, kinds of binary search tree data structures that use rotations to maintain balance.
AVL and is
Similar to red-black trees, AVL trees are in general not weight-balanced, that is sibling nodes can have hugely differing numbers of descendants.
After inserting a node, it is necessary to check each of the node's ancestors for consistency with the rules of AVL.
Automatic vehicle location ( AVL or ~ locating ; telelocating in EU ) is a means for automatically determining the geographic location of a vehicle and transmitting the information to a requester.
The main purpose of using AVL is not only to locate the vehicles, but also to obtain information about engine data, fuel consumption, driver data and sensor data from i. e. doors, freezer room on trucks or air pressure.
Another scenario for sensor functions is to connect the AVL to driver information, to collect data about driving time, stops, or even driver absence from the vehicle.
AVL technology is predominately used when applying vehicle tracking to fleet or driver management solutions.
Since only basic GIS information is included, if AVL was available, it would simply display service vehicle locations on a map.
If an AVL system is used, the CAD system will look through a list of most recent reported vehicle positions.
For example, where everyone is used to the convenience of automatic vehicle location ( AVL ), an AVL outage can suddenly increase staff workloads.
A related device classification, specific to the transportation industry, is called automatic vehicle location ( AVL ).
This is loosely similar to AVL trees, in that the actual rotations depend on ' balances ' of nodes, but the means of determining the balance differs greatly.
Since AVL trees check the balance value on every insertion / deletion, it is typically stored in each node ; scapegoat trees are able to calculate it only as needed, which is only when a scapegoat needs to be found.
AVL and its
Under the Valencian Statute of Autonomy, the Acadèmia Valenciana de la Llengua ( AVL ) has been established as its regulator.
Because most AVL consists of two parts, GPS and GSM modem with additional embedded AVL software contained in a microcontroller, most AVL systems are fixed for its purposes unless they connect to an open bus system for expansion possibilities.
AVL and two
Specifically, Lehman and Carey's article describes a T-tree balanced like an AVL tree: it becomes out of balance when a node's child trees differ in height by at least two levels.
AVL and .
AVL trees are often compared with red-black trees because they support the same set of operations and because red-black trees also take O ( log n ) time for the basic operations.
Because AVL trees are more rigidly balanced, they are faster than red-black trees for lookup intensive applications.
Both AVL trees and red-black trees are self-balancing binary search trees, so they are very similar mathematically.
AVL trees are more rigidly balanced than red-black trees, leading to slower insertion and removal but faster retrieval.
* Simple implementation — simpler than other self-balancing binary search trees, such as red-black trees or AVL trees.
