Diameter in a graph
WebApr 1, 2024 · An orientation of an undirected graph G is an assignment of exactly one direction to each edge of G. The oriented diameter of a graph G is the smallest … WebSince G has diameter exactly 2, w is adjacent to some neighbor of v. Let s = deg ( w). Because G has diameter 2, each of the n − 2 − s neighbors of v that are not neighbors of w must be adjacent to some neighbor of w. Hence, there are a total of at least. ( n − 2) + s + ( n − 2 − s) = 2 n − 4. edges in G.

WebJul 19, 2024 · I know that a complete bipartite graph k_ {n,m} has a diameter equals one when m=n=1 and 2 otherwise. My question is about a bipartite graph K_ {n,n} with two partite sets of vertices U and V of size n where each vertix from U is adjacent to only one vertix from V. What is the diameter of this graph? Thank you graph-theory Share Cite … WebThis link provides an algorithm for finding the diameter of an undirected tree using BFS/DFS.Summarizing: Run BFS on any node s in the graph, remembering the node u discovered last. Run BFS from u remembering the node v discovered last. d(u,v) is the diameter of the tree.
WebFor your first question, look at $C_ {2n+1}$, the cycle graph on $2n+1$ vertices. Its diameter is $n$, since the distance between two vertices maximally far apart is only $n$: there is a path of length $n+1$ between them, but it’s the longer way round the cycle. The girth, however, is clearly $2n+1$. WebWhat is the diameter of a graph in graph theory? This is a simple term we will define with examples in today's video graph theory lesson! Remember that the d...
