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.
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.
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 O
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.
AVL and search
Both AVL trees and red-black trees are self-balancing binary search trees, so they are very similar mathematically.
* Simple implementation — simpler than other self-balancing binary search trees, such as red-black trees or AVL trees.
* AVL trees, Red-black trees, splay trees and Tango Trees which are instances of self-balancing binary search trees ;
AVL and insertion
AVL trees are more rigidly balanced than red-black trees, leading to slower insertion and removal but faster retrieval.
AVL and .
Because AVL trees are more rigidly balanced, they are faster than red-black trees for lookup intensive applications.
Under the Valencian Statute of Autonomy, the Acadèmia Valenciana de la Llengua ( AVL ) has been established as its regulator.
tree and is
Just because a tree or other object appears in a certain spot is absolutely no reason to place it in the same position in the painting, unless the position serves the design of the whole composition.
Now the thing for us to do is to find ourselves a couple of those wonderful flowering currants such as the red Ribes sanguineum of our Pacific Northwest, or otherwise a good sloe tree, or perhaps some nice pussy willow in bloom, preferably one with male or staminate catkins.
This is in honor of John Ledyard, class of 1773, who scooped a canoe out of a handy tree and first set the course way back in his own student days.
Apollo as a handsome beardless young man, is often depicted with a kithara ( as Apollo Citharoedus ) or bow in his hand, or reclining on a tree ( the Apollo Lykeios and Apollo Sauroctonos types ).
Young of the Cuban tree frog ( Osteopilus septentrionalis ) can occasionally be cannibalistic, the younger tadpoles attacking a larger, more developed tadpole when it is undergoing metamorphosis.
The granular poison frog ( Oophaga granulifera ) is typical of a number of tree frogs in the poison dart frog family Dendrobatidae.
The usually nocturnal Cuban tree frog ( Osteopilus septentrionalis ) produces a rain call when there is rainfall during daylight hours.
Less can be said about the Asterales themselves with certainty, although since several families in Asterales contain trees, the ancestral member is most likely to have been a tree or shrub.
The calcium carbonate dust is a respiratory irritant and the particles can penetrate into the lower respiratory tree and cause irritant bronchitis and other respiratory irritation responses.
Amber is fossilized tree resin ( not sap ), which has been appreciated for its color and natural beauty since Neolithic times.
It is thought that, in addition to exuding onto the surface of the tree, amber resin also originally flowed into hollow cavities or cracks within trees, thereby leading to the development of large lumps of amber of irregular form.
Both the Latin and the Germanic words derive from the Proto-Indo-European root el -, meaning " red " or " brown ", which is also a root for the English words " elk " and another tree: " elm ", a tree distantly related to the alders.
Old Norse askr literally means " ash tree " but the etymology of embla is uncertain, and two possibilities of the meaning of embla are generally proposed.
