Write down true (T) or false (F) for each statement. Statements are shown below If a graph with n vertices is connected, then it must have at least n − 1 edges. If a graph with n vertices has at least n − 1 edges, then it must be connected. If a simple undirected graph with n vertices has at least n edges, then it must contain a cycle. If a graph with n vertices contain a cycle, then it...

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...

G3: I can determine whether a graph has an Euler trail (or circuit), or a Hamiltonian path (or cycle), and I can clearly explain my reasoning. Answer each question in the space provided below. 1. Draw a simple graph with 7 vertices and 11 edges that has an Euler circuit. Demonstrate the Euler circuit by listing in order the vertices on it. 2. For what pairs (m, n) does the complete bipartite graph, Km,n contain a Hamiltonian cycle? Justify your...
