WebJan 15, 2024 · Exercises 1: Now that basic concepts of graphs are discussed, the following exercises are a good method to practice: How many nodes are in the above graph? How many edges are in the above... WebSince deg v < ν 2 we remove at most ν degrees from the total degree of the graph. The average degree of the n − 1 vertex graph is then. ν n − 1 ≥ n ν − ν n − 1 = ν. More specifically, the average degree is non-decreasing. Therefore by the inductive hypothesis, there exists a subgraph of G ∖ { v } with minimum degree at least ... WebThis page shows some corrected exercises about graph theory modeling and trees.
