Generating a Schedule

My friend asked me for help with the following task:

He needs to generate a tennis schedule for his league of 10 people. There are 37 weeks, and 8 people play per week (2 people sit out per week). First of all, he wants everyone to play about the same amount of time. This part is easy to figure out.

+ Show Spoiler [Calculation of how many times people w…] +

There are 8 people playing per week for a total of 37 weeks, so there are 296 people-weeks. Divide that by the total number of players (10) to get 29.6 weeks played. So, I suppose that means 6 people will play 30 times while 4 people will play 29 times.


Each week, there are two games of doubles. Therefore, 2 people on team A play 2 people on team B, while 2 people on team C play 2 people on team D. My friend needs to mix it up each week so that everyone is paired with different people, and goes up against different combinations of opponents. He was going to do it all by hand out on paper and tally it up in order to keep it as fair and diverse as possible, but I told him to hold on since it's much easier to do this with planning, and possibly the help of a computer.

What would you consider an easy solution to this problem? The methods I can think of for doing a 'good' job would be time consuming and would require me to look some stuff up that I haven't done in a while, so I figured I'd open it up to suggestions. There might be a trivial way to do this that isn't occurring to me. Thanks in advance for anyone who offers any advice.

I am such a nerd that I actually love solving problems like this...unfortunately my first day of classes starts in 8 hours so I can't really sit down and help right now. If you still are looking for assistance tomorrow when my classes finish (which is unlikely) I will probably post here/ping you on irc. Good luck!

Well I'll give some of my 2 cents:
I think the total number of doubles are this:
First you pick 4 players out of 10, that is 10 choose 4.
Then you pick a team out of those 4 players, that's 4 choose 2.
So total number of doubles will be
(10 chose 4) * (4 choose 2) = 1260 possible games of doubles.

You have 37 weeks, each week you play 2 games, that's 74 total games of doubles.

So I think as long as you make the match up scrambled enough, it won't be big of a difference.
Life is run, it is dance, it is fast, passionate and BAM!, you dance and sing and booze while you can for now is the time and time is mine. Smile and laugh when still can for now is the time and soon you die!
