Ties of the Matrix: An Exercise in Combinatorics 51

mikejuk (1801200) writes "The Matrix Reloaded started something when 'The Merovingian' wore a number of very flashy ties. The problem was that we thought we knew how many ways you can tie a tie. The number of ways had been enumerated in 2001 and the answer was that there were exactly 85 different ways but the enumeration didn't include the Matrix way of doing it. So how many "Merovingian" knots are there? The question is answered in a new paper, More ties than we thought [PDf], by Dan Hirsch, Meredith L. Patterson, Anders Sandberg and Mikael Vejdemo-Johansson. The methodology is based on the original enumeration and an interesting application of language theory. The idea is to create a programming language for tying ties and then work out how many programs there are. For single depth tucks there are 177,147 different sequences and hence knots. Of these there are 2046 winding patterns that take up to 11 moves, the same as the The Merovingian knot and other popular knots, and so these are probably practical with a normal length necktie."

    Tie boy: Do not try and tie the tie. That's impossible. Instead... only try to realize the truth.
    Neo: What truth?
    Tie boy: There is no tie.
    Neo: There is no tie?
    Tie boy: Yes, you jackarse, this is a techie film and people don't wear ties unless they dropped in accidentally from the Wall Street movie set next door.

It is the distraction that has been pushed into your eyes blind you from the truth.

    Did it?

      The Matrix Reloaded started something when 'The Merovingian' wore a number of very flashy ties... the thing it started was millions of geeks saying what a shit film it was.

        Matrix Reloaded was merely a disappointing film. Matrix Revolutions was a shitty, nasty sorry excuse and complete waste of time for a film. Mostly because it wasn't set inside the fucking Matrix. Honestly, if you're going to have a final war between man and machine, set it up to occur inside the matrix, not just the final fight. An army of super humans against machines.... much better than that mech crap we all fell asleep watching.

        Now you've got me started ... Ties pfft ... goddam

      Whatever it may have started, a love of neckties was not it.

      I had a very brief moment reading this summary when I thought, "Gee, I didn't know there was mathematical complexity snuck into the Merovingian's ties." Then I thought, "Damn, I wish they'd taken that four hours of thought into the script. They could have doubled the satisfaction value of the story with that effort."

    Nice article [xirdalium.net] about the matrix ties.

    Those fancy knots are very nice, but how do you clip it to your shirt?

  • Hmmmm... geeks don't wear ties and this was published back in January (3 months ago), and the videos have been on Youtube [youtube.com] for years. How is this news?

    • Perhaps published earlier, but I had never heard of this. To those of us intrigued by topology and algorithms (and a bit of whimsy) this article is absolutely delightful. I'll have to pull out one of my ties and try some of these out.

  • I thought I read: Of these there are 2046 winding patterns that take up to 11 movies
  • For someone seemingly intelligent enough to try and enumerate the tie options in code, they were brain dead fucking stupid enough to try to illustrate it with small pictures of a black tie on a black shirt.

    Sheer genius.

  • They didn't think to just make a phonecall to the producers of the movie?

  • If I remember correctly, James Bond didn't trust a man who used anything except a Double Windsor to tie his tie. But that was a long time ago... I think about the time I stopped reading Ian Fleming. :-)
