In a cycle of 25 vertices, all vertices have degree as 2. 2) n = 3, Here, in this graph let us suppose vertex A is coloured with C1 and vertices B, C can be coloured with colour C2 => chromatic number is 2 In the same way, you can check with other values, Chromatic number is equals to 2, A simple graph with no odd cycles is bipartite graph and a Bipartite graph can be colored using 2 colors (See this). c) Simple Graph Let G be the non-planar graph with the minimum possible number of edges. Option III) 7,6,6,4,4,3,2,2 → 5,5,3,3,2,1,1 → 4,2,2,1,1,0 → 1,1,0,0,0 → 0,0,0,0 so its graphical. Hence, we can eliminate because S1 = S4. An Eulerian cycle exists if and only if the degrees of all vertices are even.And an Eulerian path exists if and only if the number of vertices with odd degrees is two (or zero, in the case of the existence of a Eulerian cycle).In addition, of course, the graph must be sufficiently connected (i.e., if you remove all isolated vertices from it, you should get a connected graph). An antihole is the complement of a graph hole. View Answer, 4. Which of the following statements for a simple graph is correct? a) 15 At least two vertices have the same degree.

Graph III has 5 vertices with 5 edges which is forming a cycle ‘ik-km-ml-lj-ji’. **NOTE**: In original GATE question paper 45 was not an option. b) False The expression ξ(G) is basically sum of all degrees in a tree. A Computer Science portal for geeks. I. Enumerating the f alse returns, 1) if L doesn’t have enough elements after the current one or 2) if any element of the list becomes negative, then it means that there aren’t enough nodes to accommodate edges in a simple graph fashion, which will lead to violation of either of the two conditions of the simple graph (no self-loops and no multiple-edges between two nodes), if not others. a) True View Answer, 9. It can be proved by induction. Using this 6-tuple the graph formed will be a Disjoint undirected graph, where the two vertices of the graph should not be connected to any other vertex ( i.e. iii) A graph is said to be complete if there is no edge between every pair of vertices. For (1, 2), there can be an edge to (1, 1), (2, 1), (2, 2), (2, 3), (1, 3) a) v=e A Hamiltonian circuit ends up at the vertex from where it started. v is number of vertices Sanfoundry Global Education & Learning Series – Data Structure. The number of edges in this graph? Let G=(V,E) be a directed graph where V is the set of vertices and E the set of edges. View Answer, 2. The resultant graph is two edge connected, and of minimum degree 2 but there exist a cut vertex, the merged vertex. there is a path of length ≤ 2 from u and v in E, Where V4 is the set of vertics in G which are not isolated, If we reverse directions of all arcs in a graph, the new graph has same set of strongly connected components as the original graph. (Such a closed loop must be a cycle.)

This Test Section specifically contain the hand picked Multiple choice Questions and Answers asked in the various competitive exam.this section mainly contain the MCQ on Data Structure and Algorithms - Graph. ….a) All vertices with non-zero degree are connected. It is important to know what days each phase occurs, the role of hormones (such as FSH, LH, estrogen, and progestrone), and what happens during each phase of the reproductive cycle Which of the following graphs has an Eulerian circuit? a) Must be connected The answer is, ξ(G) and ξ(T) is same for two trees, then the trees have same number of vertices. There can be total 6C4 ways to pick 4 vertices from 6. d) Complete Graph d) (n*n-n+2*m)/2 First we can check if there is an Eulerian path.We can use the following theorem. i) Network is a graph that has weights or costs associated with it. A graph with all vertices having equal degree is known as a __________ Below is a cyclic graph with 5 vertices and its complement graph. c) Must have no loops or multiple edges , dn → Then, D is graphical if and only if D0 is graphical. View Answer, 11. = 800 + 106 + 106 There is an edge between (a, b) and (c, d) if |a − c| <= 1 and |b − d| <= 1. Note that there can be self-loop as mentioned in the question. And A, B, C and D should have their degree as <3, 3, 3, 1> respectively. In graph theory, a cycle graph or circular graph is a graph that consists of a single cycle, or in other words, some number of vertices (at least 3, if the graph is simple) connected in a closed chain.The cycle graph with n vertices is called C n.The number of vertices in C n equals the number of edges, and every vertex has degree 2; that is, every vertex has exactly two edges incident with it. It's degree will also become as 3. Computer Science Engineering (CSE) c) 2,4,5 e is number of edges In complement graph, all vertices would have degree as 22 and graph would be connected. c) (n*n-n-2*m)/2 View Answer, 10. d) A graph may contain no vertices and many edges Trivia quiz which has been attempted 2885 times by avid quiz takers.

Construct a new graph G3 by using these two graphs G1 and G2 by merging at a vertex, say merge (4,5). This test is Rated positive by 94% students preparing for Computer Science Engineering (CSE).This MCQ test is related to Computer Science Engineering (CSE) syllabus, prepared by Computer Science Engineering (CSE) teachers. (Q) The line graph of a clique is a clique. There can be 6 different cycle with 4 vertices. Which of the following statements is true for every planar graph on n vertices? The degree sequence of a simple graph is the sequence of the degrees of the nodes in the graph in decreasing order.

Which of the following sequences can not be the degree sequence of any graph? If we add a vertex, then the new vertex (if it is not the first node) increases degree by 2, it doesn't matter where we add it. These graphs have 5 vertices with 10 edges in K5 and 6 vertices with 9 edges in K3,3 graph. a) 1,2,3 The objects of the graph correspond to vertices and the relations between them correspond to edges.A graph is depicted diagrammatically as a set of dots depicting vertices connected by lines or curves depicting edges. 2 III minimum possible number of edges present in a plane without crossing edges written, thought.
