An adjacency list represents a graph as an array of linked lists. The index of the array represents a vertex and each element in its linked list represents the other vertices that form an edge with the vertex. For example, we have a graph below. An undirected graph. We can represent this graph in the form of a linked list on a computer as shown ...The complete bipartite graph, \(K_{m,n}\), is the bipartite graph on \(m + n\) vertices with as many edges as possible subject to the constraint that it has a bipartition into sets of …A graph with an odd cycle transversal of size 2: removing the two blue bottom vertices leaves a bipartite graph. Odd cycle transversal is an NP-complete algorithmic problem that asks, given a graph G = (V,E) and a number k, whether there exists a set of k vertices whose removal from G would cause the resulting graph to be bipartite.The examples of complete graphs and complete bipartite graphs illustrate these concepts and will be useful later. For the complete graph K n, it is easy to see that, κ(K n) = λ(K n) = n − 1, and for the complete bipartite graph K r,s with r ≤ s, κ(K r,s) = λ(K r,s) = r. Thus, in these cases both types of connectivity equal the minimum ...I can see why you would think that. For n=5 (say a,b,c,d,e) there are in fact n! unique permutations of those letters. However, the number of cycles of a graph is different from the number of permutations in a string, because of duplicates -- there are many different permutations that generate the same identical cycle.

A perfect graph is a graph G such that for every induced subgraph of G, the clique number equals the chromatic number, i.e., omega(G)=chi(G). A graph that is not a perfect graph is called an imperfect graph (Godsil and Royle 2001, p. 142). A graph for which omega(G)=chi(G) (without any requirement that this condition also hold on induced subgraphs) is called a weakly perfect graph.

3. Unweighted Graphs. If we care only if two nodes are connected or not, we call such a graph unweighted. For the nodes with an edge between them, we say they are adjacent or neighbors of one another. 3.1. Adjacency Matrix. We can represent an unweighted graph with an adjacency matrix.

An undirected graph that has an edge between every pair of nodes is called a complete graph. Here's an example: A directed graph can also be a complete graph; in that case, there must be an edge from every node to every other node. A graph that has values associated with its edges is called a weighted graph. The graph can be either directed or ...
