WebIn the mathematical field of graph theory, a bipartite graph (or bigraph) is a graph whose vertices can be divided into two disjoint and independent sets and , that is every edge connects a vertex in to one in .Vertex sets and are usually called the parts of the graph. Equivalently, a bipartite graph is a graph that does not contain any odd-length cycles.. … WebA graph is Eulerian if it has an Eulerian circuit. The degree of a vertex v in a graph G, denoted degv, is the number of edges in G which have v as an endpoint. 3 Exercises Consider the following collection of graphs: (a) (b) (c) (d) (e) (f) (g) (h) 1. Which graphs are simple? 2. Suppose that for any graph, we decide to add a loop to one of the ...
