The system used to compose the league schedule is "counter-clockwise circuit." The team with the highest slot number must always be positioned in the last row of the grid.įor each subsequent iteration the highest slot number of grid alternates left and right position left column (home) and right (away). HH or AA match in the two consecutive rounds. The sequence of alternations HOME / AWAY matches for every teams in the division league, should be retained if possible.įor any team in the division league at most once in the sequence of consecutive matches HAHA, occurs the BREAK of the rhythm, i.e. If the division is composed of n teams, the championship takes place in the n-1 rounds. The requirements of the algorithm can be defined by these four rules:Įach team must meet exactly once, and once only, the other teams in the division league. REQUIREMENTS for the BALANCED ROUND ROBIN algorithm Pairs = set((x, y) for x in teams for y in teams if x != y)įor (ht, at) in season_schedule_order(teams, pairs): 'gefle', 'hacken', 'halmstad', 'helsingborg']) Teams = set(['aik', 'djurgarden', 'elfsborg', 'gais', Rev_pairs = set((y, x) for (x, y) in r_pairs) # Check that two teams doesn't face each other again. R_teams = set(x for (x, y) in r_pairs) | set(y for (x, y) in r_pairs) # Check that each team is present once in the round.
R_pairs = set(sample(pairs, n_games_per_round)) It also is very inefficient because itīuilds on using the random sample function and hoping to get it right: from random import sample It gets stuck in the while-loop quite often. The main problem with the algorithm is that For instance, one team shouldn't play 8 home games andīelow is what I got now. Is possible to always fulfill this constraint, so it is more a nice to The away team and the other rounds as the home team. Round, the game (b, a) should not be played in the ext one.Īlso, as much as possible every team should play every other round as To make the schedule look more natural, two teams should not face each Number of teams) in which each team is paired with another one. Of rounds where each round consists of n / 2 games (where n is the The constraint is that the game list should be groupable into a number
Way that it satisfies the constraint of a valid game schedule and also List of teams the following would do: set((x, y) for x in teams for y in teams if x != y)īut I also want to ORDER the games in chronological order in such a To generate a set of all games in the season is easy, if teams is a For example, imagine a sports season in which each team playsĮach other, one time as home team and the other as a visitor team on Nothing can be left to chance, so everything can’t be left to one man.I'm looking for an algorithm to generate a schedule for a set of

TV partners are paying out expensive contracts, like that $2.66 billion the NBA gets annually from ESPN and TNT. Efficiency is sought as you hit the big time. These days, if Winick were still on the job, that computer excuse wouldn’t be a lie. These two are associated with a wilder, woolier, pre-corporate time when the future was more an act of invention than the manifestation of automated fatalism. I was the computer.” Both Winick and Pinchbeck now are beloved in sports league circles, even if teams were cursing their choices back then. As Winick told Howard Beck in a 2015 Bleacher Report story: “I tell the teams, ‘Hey, that’s the way the computer did it. He did it for three decades, and in his latter years on the job, used the trappings of modernity as a means to shift blame. Matt Winick was the NBA’s Val Pinchbeck, the man who slowly, personally constructed the 1,230 game schedule within a tornado of yellow legal pads. Other leagues had too many games to fit on a pegboard, but they employed similarly artisanal methods of mapping the future. In the NFL, the late Val Pinchbeck would slowly piece together the entire football slate on a giant pegboard. In the not so distant past, fallible humans came up with the schedule for our sports leagues.
