Here is a 9 round schedule.  All the partnerships are different and every player has one bye round.

(m6 f8 v m1 f5) (m7 f2 v m3 f3) (m5 f4 v m8 f1) (m4 f7 v m2 f6)
(m1 f7 v m3 f1) (m4 f4 v m6 f3) (m2 f9 v m5 f6) (m9 f2 v m7 f5)
(m4 f2 v m8 f8) (m1 f3 v m5 f9) (m2 f5 v m3 f4) (m6 f1 v m9 f6)
(m1 f2 v m2 f4) (m3 f7 v m5 f8) (m7 f3 v m8 f5) (m4 f9 v m9 f1)
(m7 f4 v m4 f6) (m8 f2 v m1 f1) (m3 f8 v m9 f9) (m6 f7 v m2 f3)
(m3 f2 v m7 f7) (m6 f5 v m5 f1) (m8 f9 v m2 f8) (m9 f3 v m1 f6)
(m2 f1 v m7 f8) (m5 f2 v m6 f6) (m8 f4 v m9 f7) (m4 f5 v m1 f9)

Thanks for your help.

I am planning to play a 9-rounds championship for 18 people. We will play on a weekly basis, so two persons will take a rest every week.
I will think about the unfairness score.

Thanks again.

I don't have any existing way of attempting to optimize the couples as you describe. The way to go about this is to define an unfairness score for a match based on how far apart the rankings of the four players were, and then look for schedules that minimize the total unfairness score for all games in the schedule.  This could even be done on an existing mixed doubles schedule, as you could consider permutations of the player numbers within each group, each permutation gives a different unfairness score, and an algorithm could be used to choose permutations that drive down the total score.

I could make a schedule without the couples balance, but how many rounds are you looking for when there are 18 players?  With four courts there will be two byes per round, so only schedules with a multiple of 9 rounds can have the same number of games for each player.

Hello again,

Is there a way to plan the matches in a way that we have well balanced couples? Let me explain myself. I am planning to rank players having the more competent on top of the list. This means that the couple m01 f01 would be "strongest". Is there a way that you can build a fixture where a higher ranked "m" plays with a lower ranked "f". I mean that it is more desirable to have this match "m04f02 vs m03f04" than this other "m03f02 vs m04f04".

I would be interested in this fixture, if possible, for 18 players (we are missing two people in the next tournament).

Thanks a lot.

Requests / Re: 36 Players Rotating Partners 2 Games a night for 8 weeks

If you need up to 11 rounds then take then take the rounds from the top of the schedule here.  No pair of players occur together together more than once, so you are free to assign each foursome to 2 vs 2 in any way you like.

Requests / 36 Players Rotating Partners 2 Games a night for 8 weeks

« Last post by YeosFriends on December 11, 2024, 01:55:50 PM »

So the Knights of Columbus I belong to has been running a cornhole league for YEARS, they have 36 Shooters, They play 2 Teams a night Rotating Partners each time. I believe they play 8 weeks sessions. In scoreholio I can do a set schedule with 32 teams but not 36, so hoping I can find someone that help with this. The rotating partners has been the biggest issue.  

Any help would be amazing.

Is it possible to make a 36 person schedule where you don't the same partner twice and don't play against the same person twice in a 8 week schedule?

For "m" to play against every other "m" you need to have more than 9 rounds.  If it's possible to have an optimal schedule, then after 10 rounds each "m" will have had 8 out of the other 9 "m"s as opponents, then in the 11th round the 2 players with byes, will still be on 8 opponents, so the theoretical minimum number of rounds is 12.  However, if you are also considering "m" against "f" then there are 10 possible opponents and the minimum number of rounds is 13.  My software is not able to achieve anything useful in 13 rounds, so the best I can offer is the schedule below in 15 rounds.  Hope that might be of some use.
