Given n nodes labeled from 0 to n - 1 and a list of undirected edges (each edge is a pair of nodes), write a function to find the number of connected components in an undirected graph. Example 1: 0 3 | | 1 --- 2 4 Given n = 5 and edges = [[0, 1], [1, 2], [3, ...
You have a graph ofnnodes. You are given an integernand an arrayedgeswhereedges[i] = [ai, bi]indicates that there is an edge betweenaiandbiin the graph. Returnthe number of connected components in the graph. Example 1: Input: n = 5, edges = [[0,1],[1,2],[3,4]] Output: 2...

As an example, consider theArrow Distributed Directory Protocol, a solution to ensure exclusive access to mobile objects in a distributed system. The distributed system is given as an undirected graphG, where vertices and edges, respectively, represent nodes and communication links. Costs are associat...
Once generalized similarity measures have been computed, each neuron is represented as an object in a graph and connected by an edge whose weight wij equals the (i,j)th entry of the generalized similarity matrix. The outcome of this step is an undirected graph similar to the example shown ...
摘要: In this paper, we give an explicit and algorithmic description of Graver basis for the toric ideal associated with a simple undirected graph and apply the basis for testing the beta model of random graphs by Markov chain Monte Carlo method.关键词:...
摘要: In 1970 Poeth [7], a student at the department of Industrial Engineering asked us to develop an algorithm for finding all cliques in an undirected graph. He needed the results for analysing the data of a sociological survey in an organisation. These data resulted in a...
In the corresponding social network modeled as a graph, a user is denoted by a vertex and an edge between two vertices means that these two users communicate a lot above some threshold and they trust each other. An online social community is usually corresponding to a dense region in such ...
