Return the radius of a graph from its enhanced routing table.
[R] = NL_G_GraphRadius(E)
Enhanced routing table.
Graph radius.
NL_G_GraphRadius computes the graph radius R in respect with the graph G defined by its enhanced routing table E. E stores all paths between any couple of distinct nodes within the network. can be generated with the application of NL_R_RT2ERT on the routing tables created from NL_R_FloodRT, NL_R_DijkstraRT, or NL_R_BellmanFordRT. For a better convenience, we already generated a scenario whith the creation of a graph composed by 100 nodes. We have also performed 5 enhanced routing tables
providing multiple paths for each connection between two nodes. The route between the nodes
and
can be extracted at the line of index
where
represents the network size. Then for each path stored into a single line, its hop length can be found in the first column, followed by its length and finally the path composed by a list of nodes ([hop length | length | path]). The radius is the minimum eccentricity of a graph (WIKIPEDIA).
