Hi there, great to find this site. 

Here is the situation.
Rotating Doubles - play 1 set with your initial partner, then you switch around players within your court
1x a week
12 weeks per session
14 players
3 courts
Each week 2 players have a Bye, 

Can you suggest a schedule? Trying to make the crew happy.

Thanks in advance.

Just checking back to see if there could be an algorithm to solve this. No worries if not, just need to know either way. Thanks.

I don't have an algorithm to solve this problem.   But just thinking about the problem, wouldn't it be better to have a multiple of 7 weeks for a session.   In 7 weeks, there are 14 byes and it should be possible to arrange that everyone has exactly one bye - and so everyone has the same number of games.   Also, it's not clear how many sets there are on a court.   If 4 players meet there are 3 different games they can play:

(A B vs C D)
(A C vs B D)
(A D vs B C)

If you only want to play 2 of these 3 sets, then that makes the scheduling much harder I think.

Thanks. While waiting, I found this site.

I plugged in my numbers and got this schedule attached.

Then while browsing this site, I decided to chart out the frequency of the opponents each player is on the court with during the 12 week session.

A labor of love, but I rather enjoyed it. Most players received 2 BYEs with 3 getting 1 BYE -- it showed me where I could plug in a sub who occasionally wants to play but can't commit every week. I learned a lot from your site. Thank you for your time and efforts. Hope my attachment appear as I can't see on preview ...
