Rank & Group Tournament
 

I have a large list of people that have ranks and are grouped by location.
From this information, I need to make a tournament schedule. Each player
needs to compete against another player from a different location and play a
different rank. For example, I would like a #1 seeded rank to play a #2
seeded rank and a #3 seeded rank, etc. Any thoughts where to start? I am
baffled. Thanks for the help!
