Schedule Request 20T 2SL 2D 5T

Rldeepcove · 08-28-2018, 05:48 PM

Hi Schedulers

If possible could someone make me a schedule for 20 teams 2 sub-leagues each with 2 divisions and 5 teams

The format I'm looking for is:
22 Games against division opponents
10 games against other division opponents
4 games against 6 interleague opponents
don't play against the other 4 teams

If possible would like to have realistic start times

I hope this isn't too much to ask for

Thanks

This type of schedule isn't easy. Any time you have an odd number of teams, either in a league or in divisions, you're going to run into complications.

Because you have an odd number of teams (5) in each division, you're going to have at least one inter-divisional game at all times, unless all or some of the teams are playing interleague games. To make that work, you'd want inter-divisional series to be the same length as intra-divisional series, because they're all going to be played at the same time. In your set-up, however, you have teams playing 22 games against each divisional opponent and 10 games against each opponent in the other division. That likely means that intra-divisional series would be either 3 or 4 games long, while inter-divisional series would be 2 or 3 games long. That could work, but it would be very complicated.

More importantly, I don't think your numbers work out. Let's say each team plays 6 series against each divisional opponent (four 4-game series, two 3-game series) and 4 series against each team in the other division (two 3-game series, two 2-game series). Those 2-game series, however, should count as "half," because, presumably, there would be two of them taking place while other teams are playing 4-game series. So that's the equivalent of three series, not four. Likewise, the interleague series are either split up into two 2-game "half" series or combined in one 4-game series. The result, then, is this:

Intra-divisional: 24 series
Inter-divisional: 15 series
Interleague: 6 series

You end up with 24 intra-divisional series and only 21 series that aren't intra-divisional. But, as mentioned before, you need to be playing at least one inter-divisional series at all times, unless all or some of the teams are playing interleague games. So, unless you add a bunch of off-days or schedule a lot of double-headers, teams would end up being idle for two or three days at a stretch because they can't play anyone. The math, in short, doesn't appear to work.

Having dealt with a more extreme version of this, I think I know how the math can work.

THE INITIAL LAYOUT

Ignoring interleague, teams play 138 total games, across either 45 or 46 series dependent on start date. I'll use 46 as the "cleaner" number to avoid cross-division shenanigans later on.
Let's assume that the maximum possible number of four-game series exist non-divisionally without creating a home/away imbalance; in other words, each team plays 4H/6A twice, 5H/5A once, and 6H/4A twice. With the 6/4 splits doable in three series instead of four, the total number of non-divisional series is 16.
Now comes the annoying part: the total number of divisional series is 30, across 4 opponents. This can be achieved in the following manner: each team plays 10H/12A once, 11H/11A twice, and 12H/10A once. The 12/10 splits are doable in seven series, and the 11/11 splits in eight series, for the proper total of 30.

COUNTING SERIES

Looking at the (non-interleague) schedule as a whole, each subleague plays 230 series among itself: 150 divisional and 80 non-divisional. These series are played across 46 half-weeks.
Each half-week must contain one of the following structures: four divisional series and a non-divisional series (4D/1N), two divisional series and three non-divisional series (2D/3N), or five non-divisional series (5N).
As it so turns out, the combination of thirty-seven 4D/1N half-weeks, a single 2D/3N half-week, and eight 5N half-weeks results in the needed total of 150D/80N.

I managed to make this schedule.

I split the intra divisions series 10//12 or 12//10.

I split the Inter-division series as 4//6 or 6//4 with one series 5//5. Every teams plays four 2-games series. This allowed me to spread the schedule in 51 series spanning 26 weeks (including the Allstar break), with 2 series/week.

Here are the complete matchup of the series.

And the characteristics of the schedule:

# 20 team schedule, 162 games
# Designed for the following configuration:
# 2 subleagues, each with 2 divisions,
# subleague divisions with 5 teams
#
# Subleagues
# 5-team divisions
# 22 games against other 4 teams in division (4-3-3H/3-3-3-3A or 3-3-3-3H/4-3-3A)
# 10 games against other 5 teams in league (4H/3-3A or 3-3H/4A or 3-2H/3-2A)
# 4 games against 6 teams in other league (4H or 4A)
#
#
# No cases of more than 13 straight days without offday
#
# No homestands or roadtrips longer than 11 games
#
# Game times set at 7:05pm 1:05pm 2:05pm 4:05pm with One Sunday game at8:05pm
#
# Season begins first Monday on or after April 1st
# Season thus ends late September/early October
#
# All-Star Game set for Tuesday of 15th week of season (early/mid-July)
