[igraph] Implementation of "Finding set of Key players on the network!

[shahab mokarizadeh]

Thanks a lot, I solved the errors, of invalid vertex id while
computing shortest path,  simple by applying your hints.

I find in the archives of the "igraph" forum, some implementation for
finding key players in a social network (following link)

I wonder whether the full algorithm is implemented or not?  Honestly I
didn't understand the optimization algorithm well.
Is there anyone who has implemented that algorithm?
