Generate schedules — generate_schedules • ffsched

Generate unique schedules for teams, presumably for a fantasy football league, but it doesn't actually have to be for that. Points are not simulated, just schedules

generate_schedules(
  league_size = .get_league_size(),
  weeks = .get_weeks_cutoff(),
  sims = 10,
  check_dups = TRUE,
  tries = ifelse(check_dups, ceiling(log(sims)), 1),
  ...,
  overwrite = FALSE,
  export = TRUE,
  dir = .get_dir_data(),
  file = .generate_schedules_file(league_size, weeks, sims),
  ext = "parquet",
  path = file.path(dir, sprintf("%s.%s", file, ext)),
  f_import = arrow::read_parquet,
  f_export = arrow::write_parquet
)

Arguments

league_size	Number of teams in the league. Can be set globally in the options. See `ffsched.league_size`.
weeks	How many weeks are in schedule. Presently, this function requires that `(league_size - 1) <= weeks < (2 * (league_size - 2))`.
sims	How many unique simulations to generate.
check_dups	Whether to check for duplicates. It's recommended to leave this as `TRUE` to ensure that you get unique results, but that may not be what you desire.
tries	How many times to re-try.
...	Additional parameters passed to `generate_schedule()`
overwrite	Whether to overwrite existing file at `path`, if it exists.
export	Whether to export.
dir	Directory to use to generate `path` if `path` is not explicitly provided.
file	Filename (without extension) to generate `path` if `path` is not explicitly provided.
ext	File extension to use to generate `path` if `path` is not explicitly provided.
path	Path to export to.
f_import	Function to import with if file exists and `overwrite = TRUE`.
f_export	Function to export with if `export = TRUE` .

Details

This function basically uses a brute force approach, hence the tries parameter.
