1. Which complete bipartite graphs Km,n, where m and n are positive integers, are trees? Justify your answer 2. How many edges does a tree with 229 vertices have? Justify your answer.
A bipartite graph is a graph in which the vertices can be divided into two disjoint nonempty sets A and B such that no two vertices in A are adjacent and no two vertices in B are adjacent. The complete bipartite graph Km,n is a bipartite graph in which |A| = m and |B| = n, and every vertex in A is adjacent to every vertex in B. (a) Sketch K3,2. (b) How many edges does Km,n have? (c) For...
Assume that the graphs in this problem are simple undirected graphs A. The minimum possible vertex degree in a connected undirected graph of N vertices is: B. The maximum possible vertex degree in a connected undirected graph of N vertices is: C. The minimum possible vertex degree in a connected undirected graph of N vertices with all vertex degree being equal is: D. The number of edges in a completely connected undirected graph of N vertices is: E. Minimum possible...
Bipartite graph is a graph, which vertices can be partitioned into 2 parts - so that all edges connect only vertices from different parts. For example, this is a bipartite graph where one part has 3 vertices (a,b,c), and the other part - 4 vertices (d.e.f.g). Note there are NO edges in-between vertices coming from the same part. a b d f e g Give the order in which nodes are traversed with BFS. After listing a node, add its...
1. You will be asked questions about graphs. The graphs are provided formally. To answers the questions, it may help to draw the graphs on a separate sheet. a Consider the graph (V, E), V = {a,b,c,d) and E = {{a,d}, {b,d}, {c, d}}. This graph is directed/undirected This graph is a tree y/n. If yes, the leafs are: This graph is bipartite y/n. If yes, the partitions are: a, d, b, c is/is not a path in this graph....
Let G -(V, E) be a graph. The complementary graph G of G has vertex set V. Two vertices are adjacent in G if and only if they are not adjacent in G. (a) For each of the following graphs, describe its complementary graph: (i) Km,.ni (i) W Are the resulting graphs connected? Justify your answers. (b) Describe the graph GUG. (c) If G is a simple graph with 15 edges and G has 13 edges, how many vertices does...
Question 16. A maximal plane
graph is a plane graph G = (V, E) with n ≥ 3 vertices such that if
we join any two non-adjacent vertices in G, we obtain a non-plane
graph. (a) Draw a maximal plane graphs on six vertices. (b) Show
that a maximal plane graph on n points has 3n − 6 edges and 2n − 4
faces. (c) A triangulation of an n-gon is a plane graph whose
infinite face boundary is a...

QotD14 Q1 Homework. Unanswered. Due in 9 hours Consider two graphs, G1 and G2, both containing N vertices. G1 is sparse and G2 is dense. Consider a vertex v in each graph. I would like to find all of the neighbors of v using an adjacency matrix. Choose the correct answer below. O A It will be faster to find the neighbors of vin G1 (the sparse graph). 0 B It will be faster to find the neighbors of vin...
Graph 2 Prove the following statements using one example for each (consider n > 5). (a) A graph G is bipartite if and only if it has no odd cycles. (b) The number of edges in a bipartite graph with n vertices is at most (n2 /2). (c) Given any two vertices u and v of a graph G, every u–v walk contains a u–v path. (d) A simple graph with n vertices and k components can have at most...
