If you take the schedule in reply#1 here, ignore the extra round, then take each game of the form (H W vs H W) and rearrange the four players to give (H H vs W W), then if H and W are the two teams, then I believe the schedule will meet the requirements that you have set.

Requests / Schedule please 2 teams of 8 players

Hi,
Have searched with little luck so posting a request.
2 teams of 8 players in a doubles competition Team A against Team B
Criteria - 4 courts, 7 rounds, Team A playing with a different partner each round
against different opposition in Team B also playing with a different partner each round.
Chatgpt and MetaAI both failed to produce a schedule meeting all the criteria.

Thanks in advance, Cheers, Bart

What would be the best way to fill in the remaining three rounds with as few repeats as possible?

Any suggestions?

Thank you Ian!

For someone who is both a math lover and event nerd, this forum and what do are just incredible.

There is an old Excel file called foursome-tournaments-v4 in this thread that you can download if you are logged in.  This will give you a solution for the related problem of 20 teams in 5 rounds with 5 games, but unfortunately I don't think there is a solution for 24 teams, the most you can manage is the 3 rounds of play shown.  Note that these schedules involve dividing the teams into 4 sub-groups, but you don't have to tell the players about this.

Requests / Yard Games Tournament

Hey,

Not sure if this one is possible, my inclination tells me no, but here goes.

I have 6 different games being played. I have 24 teams.

I would like to break the teams into groups of 4 and have a round robin at each game, but id like the grouping to be different for each game.
So each team would play a total of 18 games(a 3 game round robin of each) by the end.

Is it possible to do this with out a team playing a game more than once or repeating opponents?

You schedule looks pretty good to me.  I have come up with the following where the referees are in square brackets:

(B C)  (G F)  [D A]
(E H)  (D A)  [B C]
(C J)  (B I)  [E H]
(G D)  (F A)  [I J]
(I E)  (H J)  [G F]
(G B)  (F C)  [H A]
(H A)  (E D)  [G I]
(J F)  (G I)  [E D]
(H C)  (E B)  [J F]
(D I)  (A J)  [B C]
(E F)  (G H)  [I J]
(A B)  (C D)  [E F]
(I J)        [C]
   
   
(C G)  (A E)  [B D]
(B D)  (F H)  [A G]
(I A)  (J E)  [C H]
(B H)  (D F)  [G J]
(C I)  (J G)  [A E]

I am not sure what criteria you will used to evaluate how good the schedule is, so let me know what you think.

Requests / Volleyball scheduling for 10 teams / 2 courts w/work team - 7 pool play matchs

« Last post by KNVBC Volleyball on January 25, 2025, 11:18:44 AM »

We are hosting a volleyball tourney where we guarantee 8 matches.  We have 10 team pools and want to give 7 pool play matches to seed teams - then move all teams to a 10 team playoff bracket based on pool seeding (I have all tie break procedures laid out).  This is a youth tournament played on 2 courts over the course of 2 days.  We need a work team on each of the pool play matches so will have 6 teams playing or working at each round.  Preference is to give as much equal rest and work / play time as possible. 

We have 80 teams across 6 divisions using 16 courts so this is a fun one.  Anyone have a program or work anything like this n the past.  I have my schedules from last couple of years but hoping someone has another view?  If no other options - any suggesting that can improve the below?

Is reply #9 here, from a conversation we had about three years ago, something close to what you are looking for?  If not, can you specify more about the format of play - how many courts, and how many rounds?
