An edge in a graph theory represents a connection between two vertices, while a vertex is a point where edges meet or terminate.

We are also able to compute in linear time a sparse certificate for 2-vertex connectivity, i.e., a subgraph of the input graph that has O(n) O ( n ) mathContainer Loading Mathjax edges and maintains the same 2-vertex connectivity properties as the input graph....
3- A-B-C-D-E 4- A-C-B-E Graphs: Graphs are very important data structures for computer science. They basically consist of 2 main parts which are nodes (or vertices) and edges that are the uni- or bi-directional paths between 2 no...
A labeling of the edges of a graph is called vertex-coloring if the labeled degrees of the vertices yield a proper coloring of the graph. In this paper, we show that such a labeling is possible from the label set 1,2,3 for the complete graph K n , n ≥ 3.关键词:Edge-labeling ...
Similarly, edge Padmakar–Ivan index of a graph G, denoted by PIe(G), is the sum over all edges uv of G of the number of edges which are not equidistant from u and v. In this paper, PIv and PIe of the generalized hierarchical product of two connected graphs are obtained. Using the...
A simple solution would be to perform aDFS(orBFS) on all the graph vertices until we encounter a vertex from which every other vertex can be reached. The time complexity of this solution isO(V × (V + E)), whereVandEare the total number of vertices and edges in the graph, respectively...

Notice that the number of edges to be added to each step has been calibrated in order to assure that the resulting graph has a number of edges comparable to the graphs obtained with ER and WS models with the same number of vertices. Notice that these results are in line with Chi and Ca...
