Also known as link-cut trees, they predate ET-trees and were the first to support dynamic-tree operations in loga-rithmic time. ST-trees represent rooted trees. The basic structural operations are link(v,w), which creates an arc from a root v to a vertex w, and cut(v), which

Nettet• Trees. For trees, we can support O(log n) time for queries and updates using Euler-Tour trees or Link-Cut trees. If the trees are only decremental, then we can support queries in constant time, as we will see in this lecture. • Planar graphs.

As far as I can tell, once you access a node v and splay it to the root, it no longer has a preferred child and therefore no longer has a right sub-tree. Furthermore, you move this tree up to the root of the entire structure, thus the link/cut tree is unbalanced at the root. bing hd wallpapers 1920 x 1080Nettet16. des. 2013 · Description: This is the implementation of link cut trees.
