Splay Trees

Splay Trees. Sean Lyn April 3, 2008. What is it?. A binary tree structure that is very similar to other trees but with additional properties. Has the potential for speeds faster than O(logn).

Splay trees

Splay trees. Outline. This topic covers splay trees A binary search tree An alternate idea to optimizing run times A possible height of O( n ) but amortized run times of Q (ln( n )) Each access or insertion moves that node to the root Operations are zig-zag and zig-zig

Splay Trees

Splay Trees. In balanced tree schemes, explicit rules are followed to ensure balance. In splay trees, there are no such rules. Search, insert, and delete operations are like in binary search trees, except at the end of each operation a special step called splaying is done.

§5 Splay Trees

Target : Any M consecutive tree operations starting from an empty tree take at most O( M log N ) time. Idea : After a node is accessed, it is pushed to the root by a series of AVL tree rotations. §5 Splay Trees. But if one node takes O( N ) time
