17 team 8 weeks

[dmd0149]

Ive been working on this for a couple weeks now and my brain is fried.

Softball Schedule

17 Teams

16 games

8 Weeks

Equal Home and Away games, 9 each

Im starting to think it isnt even mathematically possible.

Ultimately its an 18 game schedule where you play 2 teams twice, still equal home v away over 9 weeks. Not sure if that helps....

Thanks

Oh its 2 games each week with no byes....

With an odd number of teams, you will have a bye each round and you will need 17 rounds.  In the link, plug in 18 players and ignore the first column (has 18 in it)--the team paired against them has the bye.  First number in each pairing is home.

Yeah we are trying to avoid a bye each round. Without taking matchups into consideredation its theortically possible to get the 17 teams in 8 weeks of plays (based solely on amount of games played and it is possible to get all 17 team to play 2 games per week) the trouble is I get into the 6th or 7th week and start noticing corners ive backed myself into from earlier decisions and teams have no other option of playing each other again.

Are you confirming its not matheticallly possible to have each team play each other once within that time frame?

That is correct.  The illustration in the link is for 9 or 10 players (or 9/10 teams) and the opponent facing 10 will have a bye if there is no 10th player/team.  To make a round robin hold more teams, more games are added to the right.  Using the space in the Crenshaw section, team 4 will be black and under where white 5 is now, team 5 (black) would replace team 4(black), and 6 would replace 1.

There is still an odd number of teams and the team facing 10 in the illustration or 18 in your table still couldn't play that round. rr3.htm

White == home   Black == away
