The connected domination number of G is the size of its smallest connected dominating set, and is denoted by γ c (G) . In this paper we determine the maximum number of edges that a connected graph with a given number of vertices and a given connected domination number can have. We ...
G. In this paper, we consider the function M(p, d) defined for p, d ⩾ 2 as the maximum number of edges a graph G can have when it has p vertices and the dimension of its incidence poset is at most d. It is easy to see that ...
We study the random intersection graph $G_N$ constructed by these caps. We prove that for $p = \\frac{c}{N^{\\al}},\\:c >0$ and $\\al >2,$ the number of edges in graph $G_N$ follow the Poisson distribution. Also we derive the strong law results for the number of ...

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]] ...
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, ...

The number of components starts at n; when merging two distinct sets, the count drops by 1. If an edge connects two already connected nodes, we can track it as an extra edge. At the end, we need enough extra edges to connect all other connected components to a central component to ...

My question, the answer to which though seemingly obvious, is more on the theoretical side: can a subgraph S of an undirected, unweighted graph G have the same number of edges as G, excluding G itself? There are no constraints on the number of vertices that S can have. My first guess...
