简单讲解 图的定义时 我们规定一个连通图的生成树是一个极小连通子图 含有N个顶点N-1个边 我们把图中带权的边最小代价生成的树成为最小生成树。 普里姆(Prim)算法prim算法适合稠密图,其时间复杂度为O(n^2),其时间复杂度与边得数目无关以顶点找顶点 考虑权值 存储方式为邻接矩阵 基本思想:假设G=(V,E)是...
Minimum spanning tree algorithms This algorithm works by discovering the smallest trees in graphs; a minimum span tree is a collection of edges connecting all vertices with the least aggregate weight. Some of the minimum spanning tree algorithms are Prim’s algorithm and Kruskal’s algorithm. Breadt...
解析:Explanation:STP is used in LANs with redundant paths or routes to prevent loops in a layer 2 switched or bridged LAN.Incorrect Answers:A, B: The primary purpose of STP is to prevent loops, not for monitoring or management of switches or VLANs.D. VLANs are used to segment a LAN...
In this lesson, we'll discuss the properties of a spanning tree. We will define what a spanning tree is and how they can be used to solve problems...
5. Minimum Spanning Tree (MST) A Minimum Spanning Tree (MST) is a subset of edges of a connected, undirected graph that connects all vertices with the minimum possible total edge weight. Finding a graph’s MST is essential in various applications, such as network design, clustering, and res...

What is the reason for running spanning-tree in a Cisco Single-Site Secure Network Foundation Solution?() A. To protect the network in case someone inadvertently creates a physical loop in it B. To ensure that if a ...
RSTP, an enhancement to STP, allows for rapid network topology convergence. However, both RSTP and STP have a defect, that is, all the VLANs on the same LAN share the same spanning tree. As a result, redundant links cannot be blocked byVLAN, and packets of all VLANs are forwarded alon...
Spanning Tree Protocol (STP) is a widely used and effective method for preventing loops in a network. It helps prevent loops by actively monitoring thenetwork topologyand selectively blocking redundant links. This ensures that there is only one active path between any two network devices. By doing...
Greedy Algorithm Greedy algorithms aim for the best solution at the moment without considering future consequences. They are used in problem solving, such as the Kruskal’s and Prim’s algorithms for finding the minimum spanning tree in a graph. Backtracking Algorithm This type is used in constrai...
