## Theoretical maximum for betweenness centralization

### Description

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 theoretical maximum (unnormalized) graph betweenness centrality score for graphs with given order and other parameters.
