Requests / Re: Am I asking for the impossible?

« Last post by Mike Von on June 20, 2025, 03:32:07 PM »

Ian,

I searched the site but couldn't find:

doubles tennis, changing partners and opponents every round
3 courts
8 rounds
player numbers can be 13, 14, 15, 16
play with a player a maximum of one time
minimize the number of times you play against any player

Are there any solutions that meets these requirements?

Any help is much appreciated.

(K O) (D L) (A F) (G I) (J N) (B C)
(A L) (H I) (C F) (G P) (B N) (E M)
(I K) (O P) (H N) (D J) (E F) (G L)

Thanks Ian.
  For this year we are only 16 teams with the 6 pits available.
  We usually like to play 5 to 6 games each Monday night.
  Again rotating through the pits available soo as no team plays on the same pit for every match.

Requests / Casino games night - 7 tables, 28 players

« Last post by sjaksloss on May 19, 2025, 12:17:21 PM »

Hi,

I am going to organize a casino games night with 7 games (tables) and 28 players. So 4 players at each table.
Each player will have to play each game only once, which means there should be 7 rounds in total.

What I also want, is try to avoid having the same people playing against each other at other tables. So besides changing tables, opponents should also change as much as possible.


I've had a look at the whist schedule, but in that schedule players end up at the same table multiple times.

I have absolutely no idea if what I want is possible, but would appreciate it if you could have a look at it 

Thanks!

Requests / Re: 48 team event

« Last post by Ian Wakeling on May 15, 2025, 03:29:19 AM »

Hi,

An interesting problem.  If each team must play each event exactly once, then there are only two possibilities.

(a) 3 teams per event with 16 events and 16 rounds.
(b) 4 teams per event with 12 events and 12 rounds.

Both of these can be found in the Foursome-Tournaments Excel file that can be found in this thread.  You need to be logged in to see the attachment.  For (b) you can use the 48 players worksheet, for (a) use the 64 players worksheet after deleting the last column of each foursome containing the players B17-B32.  If you wish you can organize the teams into 3 groups (option a), or 4 groups (option b).

Requests / 48 team event

« Last post by Marquel1989 on May 07, 2025, 01:17:39 AM »

Trying to schedule a 48 team schedule. 

Want all 48 teams competing at the same time. And I want 3 or 4 teams competing per event (whichever works better) 

I am flexible with the number of events/rounds (e.g 10 11, 12 or whatever works best), but each team should play each event just once. 

However, trying to minimize the amount of times that the same teams play against each other. (Each team is not required to play every team, but don’t want any team to play another team more than once, if possible).

Comments and Thanks / Excel with Macro to create fixtures with dates.

« Last post by TRW on April 23, 2025, 12:40:14 PM »

Over 10 years I have created an Excel file with Macro that creates dates for up to 700 matches automatically. Info required includes season start & end, bank holidays, courts availability by day of the week, team holidays, no clash teams etc. I use it create fixtures twice a year for around 20 clubs with over 100 teams in around 10 divisions. It takes several hours to run on decent workstation but the results would be almost impossible to achieve manually.
If you are interested please get in touch. I am not looking for payment, just don't want to waste 10 years of development.
