Dynamic tree cut algorithm

WebAbstract. A data structure is proposed to maintain a collection of vertex-disjoint trees under a sequence of two kinds of operations: a link operation that combines two trees into one by adding an edge, and a cut operation that divides one tree into two by deleting an edge. Each operation requires O (log n) time. WebA link/cut tree is a data structure for representing a forest, ... Link/cut trees can be used to solve the dynamic connectivity problem for acyclic graphs. Given two nodes x and y, they are connected if and only if FindRoot(x) = FindRoot(y). ... link/cut trees can be used to improve the running time of Dinic's algorithm from () to (⁡). See ...

WebJan 26, 2024 · Relating to the problem of dynamic maintenance of all-pair min(s, t)-cut, Hartmann et al. gave a fully dynamic algorithm for Gomory-Hu tree. Though the algorithm performs well on some real world data, in the worst case the algorithm is as bad as computing the Gomory-Hu tree from scratch. WebSo the algorithm calculates in a top down approach the maximum revenue for rod length 1,2,3 to get the final answer. The recursion tree would explain it more clearly. The recursion tree shows a recursive call resulting from rodCutting(price,4). This figure clearly explains why the computation time for the algorithm is so ridiculous.
