A spanning tree (blue heavy edges) of a grid graph. In the mathematical field of graph theory, a spanning tree T of an undirected graph G is a subgraph that is a tree which includes all of the vertices of G. In general, a graph may have several spanning trees, but a graph that is not connected will not contain a spanning tree (see about spanning forests …Graph Theory - Fundamentals. A graph is a diagram of points and lines connected to the points. It has at least one line joining a set of two vertices with no vertex connecting itself. The concept of graphs in graph theory stands up on some basic terms such as point, line, vertex, edge, degree of vertices, properties of graphs, etc.Graph isomorphism. In graph theory, an isomorphism of graphs G and H is a bijection between the vertex sets of G and H. such that any two vertices u and v of G are adjacent in G if and only if and are adjacent in H. This kind of bijection is commonly described as "edge-preserving bijection", in accordance with the general notion of isomorphism ...Two graphs that are isomorphic must both be connected or both disconnected.

They are called 2-Regular Graphs. Complete Graph. A simple graph with ‘n’ mutual vertices is called a complete graph and it is denoted by ‘K n ’. In the graph, a vertex should have edges with all other vertices, then it called a complete graph.A complete graph with n vertices (denoted by K n) in which each vertex is connected to each of the others (with one edge between each pair of vertices). Steps to draw a complete graph: First set how many vertexes in your graph. Say 'n' vertices, then the degree of each vertex is given by 'n – 1' degree. i.e. degree of each vertex = n – 1.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 problem is …We present upper and lower bounds on these four parameters for the complete graph K n on n vertices. In three cases we obtain the exact result up to an additive constant. In particular, the local page number of K n is n / 3 ± O ( 1), while its local and union queue number is ( 1 - 1 / 2) n ± O ( 1). The union page number of K n is between n ...A complete graph invariant is computationally equivalent to a canonical labeling of a graph.
