I had read a paper of "Characterization of protein-interaction networks in tumors", In table of graph parameters, It has a parameter of **Graph Centrality** and said:

**GCi = 1/ max(d(i,j)**

and describe:

max(d(i,j))is the length of the shortest path between vertices i and j for a given vertices i. This is a define tod(i,j).

I think this is wrong and :

max(d(i,j))is the longest length of the shortest path between vertices i and j for a given vertices i.

This parameter what is say? and I think right?
