    LD Gift exchange is on

    So I ran the match-up script for the LD gift exchange 2011 and just sent out the mails to all the participants.

    It’s 33 participants in total, and unfortunately some europeans got other europeans for a sendout. I hope though that the script ran just fine. I actually don’t know who got who for the gift exchange. I could look it up in the database, but that would be only half the fun.

    So if there was any mistake with the match-up and you got someone from your own country, please contact me.

    But so long, go shopping and send out the gifts until the 30.th of November.

      With only 33 participants it would probably be easier to match people by hand.

      For an algorithm:
      1. Order list of names by continent, starting with the biggest continent and ending with the smallest.
      2. Considering each name in turn (giver), select recipient as the first unused name in the list that belongs to a different continent.
      3. As long as the biggest continent has <50% of total persons, it is guaranteed to match all people inter-continentally.
