GraphPeriphery

GraphPeriphery[g]

gives vertices that are maximally distant to at least one vertex in the graph g.

GraphPeriphery[{vw,…}]

uses rules vw to specify the graph g.

Properties & Relations  (8)

In a connected graph, the periphery can be found using VertexEccentricity:

Undirected connected graphs have at least two vertices on the periphery:

For a CompleteGraph, the periphery includes all vertices:

For a PathGraph with positive weights, the periphery consists of the endpoints:

With non-negative weights, the periphery forms two paths ending at the respective endpoints:

For a CycleGraph, all vertices are at the periphery:

For a WheelGraph of size 5 or more, all vertices but the hub are at the periphery:

For a GridGraph, the periphery consists of the vertices at the corners:

For a CompleteKaryTree, the periphery consists of the leaves:
