Requests / Re: 10 golfers (3-ball, 3-ball & 4-ball) 4 rounds

« Last post by Ian Wakeling on March 22, 2024, 04:42:00 AM »

There is indeed nothing tidy here.  There is a perfect solution for 9 players which you can find here.  If you truly want everyone to play each other, the only way of achieving this is for two of the players in the foursome to be fixed.  So take the schedule I linked to, and to the four threesomes that contain player I add player J.

Requests / 10 golfers (3-ball, 3-ball & 4-ball) 4 rounds

« Last post by BTM on March 21, 2024, 05:48:50 AM »

Morning All (well it is here in the UK!)

I'm off to Spain in May with 9 chums to play 4 rounds of golf over 4 days.

I know there's no tidy solution to this one, but most grateful for any assistance of how we can play in groups of 3, 3 and 4 over the 4 days with each golfer (hopefully) playing with each of the others.

Many thanks as ever

BTM

What you are asking is not possible - there needs to be 16 players or more if you want no pair of players to be on court together more than once.

I think the schedule below is the best that you can do.  There are 18 pairs of players who meet twice, and 12 pairs who never play together.

 (12  9 v  1  4)  ( 6  3 v  8 11)  ( 2  5 v 10  7)
 ( 2  4 v  5  6)  ( 3 12 v  7  9)  (10  8 v  1 11)
 ( 8  6 v 10  9)  ( 4 11 v  7  2)  ( 1 12 v  5  3)
 (11  2 v  9  1)  ( 3  8 v  4  5)  (12  7 v  6 10)

Requests / Doubles schedule for 12 players,

« Last post by Monica on March 20, 2024, 10:50:16 AM »

(Sorry in advance - my English is not the best...)

I need a schedule for a tennis tournament. 12 players, 3 courts, 4 rounds of doubles. 
I'm trying to optimize it so that every player only plays once with OR against any other player. If that is not possible than only once with another player and only once against that other player. So that every player plays with/against as many different players as possible.

I already have been trying for days but with no success... hope you can help.

Requests / Re: 10 Player Mixed Round Robin

There is nothing nice for this scenario.  I presume you are also interested in balancing the same sex oppositions, in which case I think you will need 8 rounds to ensure all the pairs at least once.  Some players will have one more game than others which is not ideal.  Can you say how many rounds you would like to play?

Looking to run a 10 player (5 male, 5 female) round robin, 2 courts.

I would like for every male to play with every female once and against every female once.

Requests / Re: 10 Team Division - Home and away with shared grounds.

« Last post by Amjad on March 11, 2024, 09:13:24 AM »

Hi Ian

I have had a look at the link that you shared for the 8 team round robin - however, i want to randomise the games that are played so that Team A does not end up playing B, C, D, E, F, G and H in the following 7 weeks and then repeats this sequence for the next 7 weeks.

I want my 9 games to be randomised for all 10 teams, yet still be able to identify which teams should be sharing grounds without any scheduling conflicts.

is there any way I can do this?  Appreciate your help with this.

Hi Bryan,

I know very little about pickleball, so I am not the one to ask when it comes to the practicalities of running competitions, but I can help with the mathematical aspects.  I have never heard of the Q program (can you provide a link?), but I am familiar with the math of "16,4", in fact what I had in mind when I mentioned the 25 players is very similar.  Have a look at the schedule here for 25 players labelled A to Y.  This becomes your court allocation schedule, and each week in the schedule becomes a period of your competition. For example in period 2 you allocate the 5 players (C H M R W) to court 3 and there they play the mini doubles tournament:

(1 2) vs (3 5)
(2 3) vs (4 1)
(3 4) vs (5 2)
(4 5) vs (1 3)
(5 1) vs (2 4)

where 1=C, 2=H, 3=M, 4=R, 5=W.  Just follow the same pattern for all 6 periods and 5 courts and you will have a schedule where all pairs of players partner once and oppose twice.  If you can't manage 6 periods then you could cut it short and you would still have optimal mixing within the constraints of your send-5-to-a-court format.  Hope that helps.

Ian that is very kind of you to offer. I am too impressed with your site. Very powerful tool.

I'm sure you've heard of the Pickleball Q program? 16 players in a round robin on 4 courts...playing with the other players once, etc., etc. To attempt to run as many players through in one day, I've modified the scoring by playing to 7, win by 1. I could retain the scoring, playing to 11 by 2.  I will need to maintain a strict 30 minute maximum playing time per (3-game) round. It takes 5 rounds to complete play (which translates into 15 matches). Five 30-minute rounds equals 2.5 hours of total playing time per Q...plus a find round robin of the top 4 players

I've got a minimum of 8 courts to work with. I'm going to offer 4 divisions for men and women. If I fill all 8 divisions, that's 128 players.  Running two Qs at the same time, on 8 courts should wrap up around dark (around 8:00 p.m.). I'm planning a lunch and a few breaks built it. 

Let me know what if you think this will work...or if I've lost my mind.

Thanks!
Bryan
