Binary Search trees offer improved average case performance for searching. However, if they are unbalanced their search performance degrades to that of a linked list. AVL trees guarantee that the difference in height of any two subtrees rooted at the same node will be at most one. This guarantees an asymptotic running time of O(log(n)) as opposed to O(n) in the case of a standard bst.
The time complexity of operations in an AVL tree is O(log n), where n is the number of nodes in the tree. This is because AVL trees are balanced, ensuring that the height of the tree remains logarithmic with respect to the number of nodes.
The worst-case height of an AVL tree is approximately 1.44 times the logarithm of the number of nodes in the tree.
The AVL tree is named after its two inventors, G.M. Adelson-Velsky and E.M. Landis.
Yes, an AVL tree is a type of binary search tree (BST) that is balanced to ensure efficient searching and insertion operations.

An AVL tree is a self-balancing binary tree. It is similar in concept to a Red-Black tree, which is also self balancing, but it is more rigorously balanced. As a result, AVL trees tend to be slower on insert than Red-Black trees, but they are faster on retrieval.

not much memory wastage.

In an AVL tree, at what condition the balancing is to be done : If the 'pivotal value' (or the 'Height factor') is greater than 1 or less than -1. niraj
An AVL tree is more efficient than a Binary Search Tree in terms of balancing and searching for elements. AVL trees are self-balancing, ensuring that the tree remains balanced after each operation, which results in faster search times compared to Binary Search Trees.
Binary Search Tree and AVL Tree are dictionary data structures. They are used for many search operations and also those operations where data is constantly inserted and deleted. AVL trees provide a better efficiency than BST as they maintain their upper bound of O(n*log n) through rotations.Eg: the map and set library in c++ isimplementedusing trees.
