Minimum Spanning Tree 我们想要在一个图中,找到一个连通的子图,且边权之和最小,我们把该子图叫做Minimum Spanning Tree (MST) 两个重要的结论 Cut Property 对于图中任意一个节点子集S,我们称为Cut,如果存在一条边ee,e有且只有一端在S中,那么一定存在一个MST包含ee Cycle Property 对于图中任意一个环,环中最...

Greedy Algorithm贪心算法
Prim’s algorithm(普里姆算法)是用于解决最小生成树(Minimum Spanning Tree, MST)问题的一种常用贪心算法。它通过逐步添加节点来构建最小生成树,并保证最终生成的树是整个图中权重之和最小的树。 算法步骤如下: 初始化:选择一个起始节点作为树的根节点,将其加入到最小生成树中。同时,将所有其他节点标记为未访问...
《Greedy》翻译:探究贪婪算法及其在不同语境下的含义 “Greedy”一词在英语中意为“贪婪的”,但在计算机科学和数学领域,其含义则更为专业且精准,通常指代一种贪婪算法(Greedy Algorithm)。 理解《Greedy》的翻译,需要从其字面意思出发,逐步深入到其在不同领域的应用和引申含义。 首先,从字面意思来看,《Greedy》最...
A common approach to solving the Activity Selection Problem is to use a Greedy algorithm. The idea is to sort the activities by their finish times and always select the next activity that finishes first. This ensures that there is always enough time to perform the maximum number of activities...
, n). Also note that due to Theorem 3.15 every extreme minimum-weight base can be obtained by the greedy algorithm by appropriately choosing a monotone nondecreasing linear extension (e1, e2,…, en) of D in Step 1. Corollary 3.17 Problem Pw has a unique optimal solution if w: E→ R ...
A minimum spanning tree (shown in red) minimizes the edges (weights) of a tree. For an example of how a simple greedy algorithm works, see:Boruvka’s Algorithm (Sollin’s Algorithm), which is a way to find aminimum spanning treewhere the sum of edge weights is minimized. ...
