Hello

Following on from my earlier question:

https://www.mapleprimes.com/questions/239620-Round-Robin-With-Double-Bye

a colleague has produced (admittedly hurriedly) a sports schedule over 14 weeks for a 8-team double bye, and a 10-team over 15 weeks. 
Looking at it, and counting the possible combinations, neither seem optimal...

The 8 team has equal byes, the 10 uneven.

Edit. Ideally no team would have 2 byes in a row. 

Is there a solution in maple over these weeks? given the min duration would be 13 weeks and the max 15 weeks?
In the previous solution by mmcdara the 8 bye schedule each team has played 6 times after week 8, but since the roster is truncated to 14 or 15, there will be some weeks when no byes are required (all teams playing) to even things up.
Similarly, the 10 bye each team has played 8 times after week 10, but since the roster is truncated to 14 or 15, there will be some weeks when no byes are required.

Any help would be welcome!

Edit: I made some counting errors. It's 28 and 45 as Carl pointed out

Hi

Can someone improve my AI code so I get to the final team's config directly, rather than a series of set iterations? thanks 

teams.mw

set 1: Michael K, Andy C
set 2: Michael G, Mitch
set 3: Jez, Dean B
set 4: Anthony B, Rik B
set 5: Ilya, Fariborz
set 6: Eugene, Tania
set 7: Bill, Stevs
set 8: Victor, Jane
set 9: Nash, Ben
 

Hi

Following on from this question, https://www.mapleprimes.com/questions/200909-Roster-Choose-Teams
I wanted to create the sequence for n>3 teams, where n:: even and two byes.
Currently, my AI-modified code produces the wrong output, can someone modify it?

# Example usage with 8 teams and 2 byes
PrintPairings(8); 

Round 1:
  1 vs 2
  3 vs 4
  5 sits out
  8 sits out
....
:Round_Robin.mw
It should be
Round 1:
  1 vs 2
  3 vs 4
  5 vs 6
  7 sits out
  8 sits out
......
etc

Hi. I'm comparing two 7x3-man teams lists. I can see there are at least 2 teams that have common members, new[1] and past[4], new[4] and past[3]. There may be others but the chat gpt code below doesn't definitively find any of them.

Hi

A padel group organises doubles tournaments with the following structure: 16 players participate in four rounds, with each round consisting of four doubles matches. Players switch partners after each round.

So what I require is some code to generate the first round matches, the second round, the third, the nth .....

note the worksheet I bastardised from Tom Leslie's work.
