Title: Scrambled Volleyball Doubles Schedule
Post by: VolleyFreak on September 07, 2017, 03:22:54 PM
I'm back with another volleyball league quandary.  Had to make it bigger & better.

Here's the scoop.  The league format is scrambled doubles, where the players play with different teammates and against different opponents throughout league play.  I've got 14 people in the league.  I've got 3 courts available per time slot, so 2 people would be on BYE each time slot.  Unfortunately, I've only got 10 total match time slots so that means some players would get 1 BYE, others would get 2.  I'm trying to figure out the league format for randomizing teammates & opponents for the league.  We'll randomly draw for the 1 or 2 BYE schedules and normalize ranking per match played to deal with the shortened season.

Any help you could provide would be greatly appreciated.  Love the site.

It's a difficult problem since there are only 10 rounds and the byes are unbalanced, but here is a possible schedule you could use.


  ( 4  9 v 10 13) ( 6 11 v  5 12) (14  7 v  3  8)   ( 2  1)
  (13  5 v  7  3) ( 6 10 v  1  2) ( 4 11 v  9 14)   (12  8)
  ( 4 13 v  8 11) (12  2 v 14 10) ( 7  5 v  1  9)   ( 6  3)
  ( 2  4 v  3 12) ( 9  7 v 11 10) ( 1  6 v 14  8)   (13  5)
  ( 2 13 v 11  1) ( 9  8 v  6  3) ( 5 14 v  7 12)   (10  4)
  (10  4 v  6  5) ( 1  8 v 12 11) (13  9 v  2 14)   ( 3  7)
  ( 4  6 v 11  7) ( 8 13 v 10  5) ( 9  3 v 12  1)   ( 2 14)
  ( 6  2 v 11  3) (12 10 v  7  8) ( 1  5 v  4 14)   (13  9)
  (10  1 v  4  3) ( 6 14 v 13  7) ( 9  2 v  8  5)   (12 11)
  (13  6 v  9 12) (11 14 v 10  3) ( 2  8 v  7  4)   ( 5  1)
