From igraph v1.2.2

##### Theoretical maximum for betweenness centralization

See `centralize`

for a summary of graph centralization.

##### Usage

`centr_betw_tmax(graph = NULL, nodes = 0, directed = TRUE)`

##### Arguments

- graph
The input graph. It can also be

`NULL`

, if`nodes`

is given.- nodes
The number of vertices. This is ignored if the graph is given.

- directed
logical scalar, whether to use directed shortest paths for calculating betweenness.

##### Value

Real scalar, the theoratical maximum (unnormalized) graph betweenness centrality score for graphs with given order and other parameters.

##### Examples

```
# NOT RUN {
# A BA graph is quite centralized
g <- sample_pa(1000, m = 4)
centr_betw(g, normalized = FALSE)$centralization %>%
`/`(centr_betw_tmax(g))
centr_betw(g, normalized = TRUE)$centralization
# }
```
