In computer science, an AVL tree (Georgy Adelson-Velsky and Evgenii Landis' tree, named after the inventors) is a self-balancing binary search tree. It was the first such data structure to be invented. In an AVL tree, the heights of the two child subtrees of any node differ by at most one; if at any time they differ by more than one, rebalancing is done to restore this property.

What is an AVL Tree? The term AVL tree was introduced by Adelson-Velsky and Landis. It is a balanced binary search tree and is the first data structure like this. In the AVL tree, the heights of the subtree cannot be more than one for all nodes. The above picture is of an AVL tree.

### AVL Trees - University Of Wisconsin–Madison

To describe AVL trees we need the concept of tree height, which we de-ﬁne as the maximal length of a path from the root to a leaf. So the empty tree has height 0, the tree with one node has height 1, a balanced tree with three nodes has height 2. If we add one more node to this last tree is will have height 3.

The main difﬁculty is that they are efﬁcient only when they are balanced. Straightforward sequences of

AVL Trees An AVL Tree is a binary search tree that has conditions on the height of each node. The height is defined to be the number of nodes in the longest path from that node to a leaf node. Thus, in the left tree in the last diagram, Eunice's height is four and Binky's height is three.

AVL trees require the heights of the subtrees of any node to differ by no more than one level, which ensures that the height is O(log N). Red-black trees can be viewed as an implementation of 2-3 trees that represents each 3-node as a pair of binary nodes, one red and one black. It can also be viewed as variation on AVL trees.

What is Tthe AVL Tree? AVL tree is a binary search tree in which the difference of heights of left and right subtrees of any node is less than or equal to one. The technique of balancing the height of binary trees was developed by Adelson, Velskii, and Landi and hence given the short form as AVL tree or Balanced Binary Tree. An AVL tree can be defined as follows:
