An AA tree in computer science is a form of balanced tree used for storing and retrieving ordered data efficiently. AA trees are named after their originator, Swedish computer scientist Arne Andersson .
The above picture is a balanced ternary search tree for the same set of 12 words. The low and high pointers are shown as angled lines, while equal pointers are shown as vertical lines. A search for the word "IS" starts at the root, proceeds down the equal child to the node with value "S", and stops there after two comparisons.
A B-tree of depth n+1 can hold about U times as many items as a B-tree of depth n, but the cost of search, insert, and delete operations grows with the depth of the tree. As with any balanced tree, the cost grows much more slowly than the number of elements.
If the two trees are balanced, join simply creates a new node with left subtree t 1, root k and right subtree t 2. Suppose that t 1 is heavier (this "heavier" depends on the balancing scheme) than t 2 (the other case is symmetric). Join follows the right spine of t 1 until a node c which is balanced with t 2.
A tournament tree can be represented as a balanced binary tree by adding sentinels to the input lists (i.e. adding a member to the end of each list with a value of infinity) and by adding null lists (comprising only a sentinel) until the number of lists is a power of two. The balanced tree can be stored in a single array.

The BAlanced Tree Overlay Network (BATON) is a distributed tree structure designed for peer-to-peer (P2P) systems. Unlike other overlays that employ a distributed hash table, BATON organises peers in a distributed tree to facilitate range search.
Our tech editor Rick Broida tried and tested quite a few different types of trackers and the Apple AirTag got top ranks. We especially love these for travel. Putting one in your luggage takes all ...
