View Full Version : Scheduling Problem
01-23-2003, 04:26 PM
I need help with a scheduling problem for a bar league.
1. Two teams play out of each bar.
2. Each bar has only one table for league play.
3. The schedule should be as balanced (home/away) as possible.
Anyone have an algorithm or any suggestions?
One group plays on Mondays the other plays on Tuesdays. Is this one of those trick questions? /ccboard/images/graemlins/smile.gif
If for some reason this is unsuitable turn it into a Scotch Doubles league.

1. Is there other teams involved?
2. Is there an even number of matches for all teams?
3. Is this a weekly schedule?
4. Will all teams be playing each other? Teams from the same bar, will they play each other at home?
If its just two teams.. per bar. and I assume its 4 teams total..
Team number 1 and 2 for the first bar
Team number 3 and 4 for the second bar
For all four teams to play each other
1 home plays 4
3 home plays 2
2 home plays 3
4 home plays 1
1 home plays 3
4 home plays 2
2 home plays 4
3 home plays 1
the 5th week.. the two home teams can play each other if they want..
Repeat this for x amount of times

Dave...How many bars are there in your league?...and how many weeks do you want to play? I have all the APA stuff for different size divisions, where all play is equal based on number of teams and number of weeks played, for as few as 4 teams, or as many as 20. Let me know, and I can send it to you.

I had the same problem when I was scheduler for the bar league I used to play in.
I ran the league through a scheduling program, but had to do the "Home" and "Aways" by hand. Thankfully, there were only 12 teams in the league at the time.

Unless I'm missing something, if there are only 4 teams total, 1 team stays on the home table and the other "home" team goes to the other bar...I think the limit is 2 "home" teams playing outta the same bar, on the same night. That way, you can always have 1 team playing at home and the other visiting another location, then switch it around for the next week.

I was asking because of a project that I am working on. I needed something to work for a varying number of teams. As an example:
1. League night is Tuesday.
2. There are 8 bars in the league with single tables for league play.
3. There are 16 teams in the league. When one of the two teams assigned to a bar is "at home" the other must be "away"
4. The home and away must be as evenly balanced as possible. Given that it would take 15 weeks to complete a schedule, I know you won't get a perfect balance. If you flip the schedule and increase it to 30 weeks you will.
After exhaustive searching, I finally found a program called "Home and Away" that generates the type of schedule I required. I really would like to know the algorithm/process that it uses, but I guess you can't have everything. I tested it on 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, and 24 teams and it worked as advertised.
The other scheduling programs I investigated were for football, basketball, etc. which didn't address the problem of two teams playing out of the same facility.
Thank you, Jimbo, Tom_In_Cincy, Scott Lee, Barbara, and Eric for your responses. I really appreciate it.
Scott, I'd still like to get a copy of your schedules.
My project should be complete by the end of February. Although I can't discuss it yet, it should be available for comment in March.
