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
Link cut tree implementation
Did you know?
Cut and link have O(1) cost, plus that of the access. FindRoot has an O(log n) amortized upper bound, plus the cost of the access. The data structure can be augmented with additional information (such as the min or max valued node in its subtrees, or the sum), depending on the implementation. Thus Path can return this information in constant time plus the access bound. So it remains to bound the access to find our running time. NettetIf you need to navigate up the tree, then the Node class needs a link to its parent node. Build an AddChild method that takes care of all the minutia of these two points and any other business logic that must be implemented (child limits, sorting the children, etc.) Share Improve this answer answered Sep 15, 2008 at 21:04 David Boike 18.5k 7 59 94

NettetThe link-cut trees solves problems in paths, you want know about the amount vertices in a subtree, for this you can use Euler Tour Tree that solves problems in components, and is very close to link-cut trees. → Reply faiyaz26 9 years ago, # ^ 0 you are saying Euler tour than using segment tree to update a range, right ?
