Description

The reach centrality of a node $w$ is the smallest distance $r$ such that any $s-t$ shortest path passing through $w$ has either $s$ or $t$ in the ball of radius $r$ around $w$.

Directed All-Nodes Reach Centrality is the version of the problem in a directed graph where you must calculate the reach centrality of each node.
