AVL Tree Full Form: A Brief Introduction
When learning about data structures, especially in the context of trees, one name that often comes up is the AVL Tree. But what exactly does “AVL” stand for, and why is it important in the world of computer science? Let’s dive into the full form and significance of this powerful data structure.

What is the Full Form of AVL?
The full form of AVL is Adelson-Velsky and Landis, named after the two Soviet mathematicians Georgy Adelson-Velsky and Evgenii Landis, who first introduced this concept in 1962. The AVL tree was the first-ever self-balancing binary search tree, solving a major issue with basic binary search trees — maintaining efficiency as the tree grows.
Why AVL Trees Matter
Before understanding the importance of an AVL tree, it’s crucial to know what makes tree structures efficient. A Binary Search Tree (BST) allows for fast searching, insertion, and deletion, but it can become inefficient when the tree becomes unbalanced, leading to operations taking longer. In a worst-case scenario, the time complexity can degrade from O(log n) to O(n).
This is where the AVL tree steps in. AVL trees automatically balance themselves during insertions and…
