Graphs: •A graph is a data structure that has two types of elements, vertices and edges. •An edge is a connection between two vetices •If the connection is symmetric (in other words A is connected to B B is connected to A), then we say the graph is undirected. •If an edge only implies one direction of connection, we say the graph is directed. Graph Theory has become an important discipline in its own right because of its applications to Computer Science, Communication Networks, and Combinatorial optimization through the design of efﬁcient algorithms. It has seen increasing interactions with other areas of Mathematics. Although this book can ably serve as a reference for many of the most important topics in Graph Theory, it even.

A graph is a pictorial representation of a set of objects where some pairs of objects are connected by links. The interconnected objects are represented by points termed as vertices, and the links that connect the vertices are called edges. Formally, a graph is a pair of sets, where V is the set of vertices and E is the set of edges, connecting the pairs of vertices. Take a look at the following graph −.

(b) A directed graph with a self-loop. In a directed graph, edges are directed; that is they are ordered pairs of elements drawn from the vertex set. The ordering of the pair gives the direction of the edge.8 The graph above has a degree sequence d = (4;3;2;2;1). These are the degrees. Data structure is a representation of logical relationship existing between individual elements of data. In other words, a data structure defines a way of organizing all data items that considers not only the elements stored but also their relationship to each other. The term data structure is used to describe the way data is stored. To develop a program of an algorithm we should select an. the way i n which standard graphs behave under minors. This deep truth is best evidenced by the work of Thor Johnson, who developed an analogue of the Robertson -Seymour Graph Minor Theory for 2 -regular digraphs under immersion. We will discuss some recent work tog ether with Archdeacon, Hannie, and Mohar in this vein. Namely, we establish the excluded immersions for certain surface.## See This Video: Graph theory in data structure pdf
