Title: Schedule for Tennis Block Time
Post by: justy96 on August 23, 2009, 12:03:25 PM

I'm having a hard time trying to work out a schedule for my block time this year. We have 9 players for 2 courts (8 people playing every week). How can I make a schedule where everyone plays the same amount of time and plays an even amount of time with the other players? We play 35 weeks. Thanks for your help!

Here is the standard Whist schedule for 9 players, it is doubles play where all possible partners occur once and all opponents twice.  The schedule has 9 rounds so you will need to generate 4 variants, each time making a different random assignment of the letters A to I to your 9 players.  Finally delete one of the 36 rounds to give a schedule for 35 weeks.

  (B C) v (D G)    (E I) v (F H)    (A)
  (C A) v (E H)    (F G) v (D I)    (B)
  (A B) v (F I)    (D H) v (E G)    (C)
  (E F) v (G A)    (H C) v (I B)    (D)
  (F D) v (H B)    (I A) v (G C)    (E)
  (D E) v (I C)    (G B) v (H A)    (F)
  (H I) v (A D)    (B F) v (C E)    (G)
  (I G) v (B E)    (C D) v (A F)    (H)
  (G H) v (C F)    (A E) v (B D)    (I)

Hope that helps.
