WebJun 23, 2024 · To find the diameter of a graph, first find the shortest path between each pair of vertices. The greatest length of any of these paths is the diameter of the graph. Regarding your question about G having 5 node and 8 vertices: Let assume each edge is weighted 1. Notice that the max E for DAG is V * ( V -1) /2 -> so in your case is 10 (5*4/2). Web3.1. The diameter of a graph In a graph G, the distance between two vertices uand v, denoted by d(u;v), is de ned to be the length of a shortest path joining uand vin G. (It is …

You need to repair it a bit. Where you say that by definition d(u,v)≤g(G), that's certainly true but it's not strong enough to complete your argument.

In graph theory, the hypercube graph Qn is the graph formed from the vertices and edges of an n-dimensional hypercube. For instance, the cube graph Q3 is the graph formed by the 8 vertices and 12 edges of a three-dimensional cube. Qn has 2 vertices, 2 n edges, and is a regular graph with n edges touching each vertex. The hypercube graph Qn may also be constructed by creating a vertex for each subset of an n-el…
