Diameter in a graph
WebAbstract For a connected graph G, the Kirchhoff index is defined as K f ( G ) = ∑ 1 ≤ i < j ≤ n R G ( v i , v j ) and the multiplicative eccentricity resistance-distance index ξ R ∗ ( G ) = ∑ { v i... WebNov 30, 2024 · The diameter in a graph. The diameter is the longest path of the shortest path between two vertices in a network or graph. To clearly understand, look at the following graph. We have 5 vertices and 7 edges. What is the diameter of the graph? It must be 2.

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 diameter among all the orientations of G. WebA graph geodesic is the shortest path between two vertices of a graph. The graph diameter is the longest possible length of all graph geodesics of the graph. PseudoDiameter finds an approximate graph diameter. It works by starting from a vertex u, and finds a vertex v that is farthest away from u.
WebMay 13, 2024 · Note that in this example, the diameter of the graph is 4; the longest shortest path is from node 6 to node 4. The randomly selected source node was 7 - the … 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.

If there are many shortest paths … WebThe degree/diameter problem is to determine the largest graphs or digraphs of given maximum degree and given diameter. General upper bounds - called Moore bounds - for the order of such graphs and …
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 possible to de ne the distance by various more general measures.) The diameter of G, denoted by D(G), is the maximum distance over all pairs of vertices in G.The
WebFeb 18, 2024 · The diameter is the longest [shortest path] in a graph. To show that the diameter is some amount requires you to construct a shortest path with that length, and showing that all other paths are at most as long as that path. For the cycle graph, opposite vertices can be used for constructing the longest [shortest path]. – Element118. sharon davisonWebdiameter. #. The diameter is the maximum eccentricity. A precomputed dictionary of eccentricities. If this is a string, then edge weights will be accessed via the edge attribute with this key (that is, the weight of the edge joining u to v will be G.edges [u, v] [weight] ).
