Due to its complexity, a lot of attention has focused on deriving approximate solutions to this problem (Takahashi and Matsuyama, 1980; Waxman, 1988; Hauptmann and Karpinski, 2013). The problem of routing with static multicast groups in wired networks is often formulated as a Steiner tree ...

The edge between uu and its parent is a bridge if and only if dp[u]=0dp[u]=0. Directing edges to form a strongly connected graph Consider the following problem. Unfortunately I don't know if you can submit solutions somewhere. This is 118E - Bertown roads. Problem 1. You are given...
Segment Tree Problems - 1- Segment Tree for the Sum— This is the basic and easiest question of the segment tree. Here is my AC simple solution 2- Segment Tree for the Minimum— Here we have to find the minimum element from a segment and can also update an index.This is also a basi...
根据第二段However,seeing ecosystem restoration as tree planting can be very dangerous because tree planting is often used as an excuse to avoid cutting carbon emissions(碳排放).In fact,if the oil and gas industry continues to increase in size,even 10 planets full of trees could not deal with...
solutions to the problem for a small constantk. Based on geometric properties of optimal location of Steiner points, we present anO(nlogn) time exact algorithm fork = 1 and anO(n2) time algorithm fork = 2. Also, we present anO(nlogn) time exact algorithm to the problem for a...
Therefore, we need a kind of more proper data container, namedTreeValue. It is designed for solving the following problems: Ease of Use: When the existing operations are applied to tree structures such as dict, they will become completely unrecognizable, with really low readability and maintainabi...
Other well-studied network optimization problems that we do not attempt to survey here include minimum cost matching (which has polynomial-time exact and approximate solutions; see [36,379,380,389]) and minimum weight triangulation (MWT) (whose complexity status is still open, although constant-fa...
