WebThe smallest eccentricity occurs at the central vertex with an eccentricity of $3$. This is your radius. Your center consists of all the vertices which have eccentricity equal to the radius, in this case $3$. For this graph, there is only a single such vertex, so your center in the single vertex labelled $3$ in the graph. WebThe eccentricity of a vertex v is the maximum distance of a vertex from v, and the eccentricity sequence of a graph is the sequence of the eccentricities of its vertices (sorted in nondecreasing order).

"WebEccentricity is basically the ratio of the distances of a point on the hyperbola from the focus, and the directrix. If the distance of the focus from the center of the hyperbola is 'c' and the distance of the vertex of the hyperbola from the center is 'a', then eccentricity of hyperbola e = c/a.

The Average Eccentricity of a Graph and its Subgraphs

WebThe more general condition of this type I can think about is the following: If G is a k -regular graph and k ≥ V ( G) 2, then all vertices have the same eccentricity. To see this, note that either G is a complete graph or for every vertex v, every non-neighbor of v is at distance exaclty 2, since they have a common neighbor. WebOct 2, 2024 · Eccentricity is defined in terms of maximum shortest path between a given node and all the other nodes in a (sub-) graph. It would not seem to make sense to talk about the maximum eccentricity for a particular node?
