24 person RR across 5 courts

[Tennis76]

Hi,

I’m trying to create a round robin schedule, and could use some help.

We are 24 players, across 5 courts, for a rotating-partners doubles tennis round robin. We will only have time for 9 or 10 rounds. I was thinking it might be best to divide the 24 players into two groups (by play level) to make the scheduling easier. For example, 10 players across 2 courts (8 playing, 2 sitting out each round) and 14 players across 3 courts (12 playing, 2 sitting out each round).

My questions are: is this the best way to split the players up? If so, could you give me a balanced schedule please for the 2 RR groups (of 10 and 14)? If not, what split do you suggest for 24 rotating doubles players across 5 courts with 9 (or 10 rounds)? And what would the best schedule be?

Thank you for any help!


Just an update here to help with the parameters I’m hoping to achieve:

- 24 players (can be split into 2 groups, I was thinking maybe a group of 10 and a group of 14)
- There are 5 courts available for each round
- A maximum of 10 rounds (9 would be better)
- Rotating partners so that each person plays with everyone once, and plays against each person at least once but not more than twice

Any help is much appreciated!!

Here is a possible 9 round schedule. All the partnerships are different, and it almost meets your opponents once-but-not-twice criterion. In particular (1 13) never oppose in the 14 player group.

10 player group (2 courts)
( 9 10 v  6  5)  ( 8  7 v  4  3)
(10  2 v  7  5)  ( 6  9 v  8  1)
( 9  8 v  7 10)  ( 3  2 v  4  1)
( 5  9 v  3  1)  ( 2  4 v  6 10)
( 5  1 v  7  4)  ( 8  2 v  6  3)
( 9  7 v  6  2)  ( 5 10 v  4  8)
( 1  7 v  8  6)  ( 9  3 v  4 10)
( 3 10 v  1  6)  ( 4  5 v  9  2)
( 8 10 v  1  2)  ( 7  6 v  3  5)

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

Note that the byes can not be balanced, so some players will have one more round than others.

Hope that helps.
