Here, The vertices of the graph can be decomposed into two sets. The two sets are X = {A, C} and Y = {B, D}. The vertices of set X join only with the vertices of set Y and vice-versa. The vertices within the same set do not join. Therefore, it is a bipartite graph.

We will frequently use the notation V(G) and E(G) to denote the vertex set and edge set, respectively, of G. If V is a ﬁnite set, then G is called a ﬁnite graph. In this book, we consider only ﬁnite graphs. A graph can be used to encode some relationship of interest between entities.

It is possible to test whether a graph is bipartite, and to return either a two-coloring (if it is bipartite) or an odd cycle (if it is not) in linear time, using depth-first search. The main idea is to assign to each vertex the color that differs from the color of its parent in the depth-first search forest, assigning colors in a preorder traversal of the depth-first-search forest. This will necessarily provide …
