Title: Party bridge 8 teams, 4 teams each in 2 houses, playing 8 months
Post by: PatG503 on May 04, 2019, 01:10:24 PM

I have been trying to schedule a party Bridge round robin and cannot figure out how to schedule 8 teams once a month, with four teams in 2 houses, playing 8 months and with as few teams as possible playing more than twice against the same team. Thanks for any help.

It can work for 7 months, where all pairs of teams play exactly once:


Mnth Hse  Tbl1    Tbl2
  1  1    2  6    3  5
  1  2    1  8    4  7
               
  2  1    1  3    5  8
  2  2    2  7    4  6
               
  3  1    4  8    5  6
  3  2    1  7    2  3
               
  4  1    1  2    4  5
  4  2    3  7    6  8
               
  5  1    1  6    2  8
  5  2    3  4    5  7
               
  6  1    2  4    3  8
  6  2    1  5    6  7
               
  7  1    1  4    3  6
  7  2    2  5    7  8


You are then free to choose anything for month 8, but you could have a play off with the best two teams paired, then the next best, and so on.

Hope that helps,

Ian
