Pairloop Doubles Mixer

Check mixer fairness limits

check_mixer_fairness

Read-only

Use this when the user wants to check social doubles schedule limits before making a rotating partners schedule. Reports usable courts, balanced sit-out totals, unavoidable consecutive rests and a counting lower bound on partner repeats for 4 to 48 players and 1 to 24 rounds. Does not claim that bounded scheduling reaches the lower bound or balance player ratings.

`rounds`	Yes	Number of rounds, a whole number from 1 to 24, e.g. 7.

`group_b`	No	Optional group B names, e.g. ["Casey","Drew"]. Partners cross groups; unequal groups may be refused if balanced rests are impossible.
`players`	Yes	4 to 48 distinct player names, e.g. ["Alex","Blair","Casey","Drew"]. Names are limited to 40 characters.
