A Few Million Virtual Monkeys Randomly Recreate Shakespeare 312

Posted by samzenpus from the simpsons-did-it dept.
First time accepted submitter eljefe6a writes "On September 23 at 2:30 PST the A Million Amazonian Monkeys project successfully recreated A Lover's Complaint. This is the first time a work of Shakespeare has actually been randomly reproduced. It is one small step for a monkey, one giant leap for virtual primates everywhere. From the article: 'For this project, I used Hadoop, Amazon EC2, and Ubuntu Linux. Since I don’t have real monkeys, I have to create fake Amazonian Map Monkeys. The Map Monkeys create random data in ASCII between a and z. It uses Sean Luke’s Mersenne Twister to make sure I have fast, random, well behaved monkeys. Once the monkey’s output is mapped, it is passed to the reducer which runs the characters through a Bloom Field membership test. If the monkey output passes the membership test, the Shakespearean works are checked using a string comparison. If that passes, a genius monkey has written 9 characters of Shakespeare. The source material is all of Shakespeare’s works as taken from Project Gutenberg.'"

      I wish I'd thought of it - and what a neat way to go about it.

      So is it safe to say you're virtually impressed with the whole affair?

      • Definitely. From the "whole-problem optimisation" of selecting individual blocks of characters and composing the whole, to the implementation of a scalable distributed algorithm, to the various approaches to processing and validating the text, to the selection of the final comparison blocks. Though I don't know why I'm supposedly only "virtually" impressed.

    • Cool? Success is a forgone conclusion and the results were written over a hundred years ago. Cool would be to have this system write something new.

      • It would be a foregone conclusion if monkeys were indeed randomly typing on a keyboard. But in practice, they tend to like certain keys leading to at best a pseudo random distribution of keystrokes. On top of that, many of the characters needed to produce the works require not just one keystroke, but a shift and a keystroke to work.

        Consequently, simulating this with virtual monkeys is almost sure to come up with a result that differs substantively from using actual monkeys to do the project.

      This experiment, while fun, isn't exactly the infinite monkey experiment.

      What's happening here (if I understand the writeup) is that the monkeys are typing random letter combinations, until they hit a small phrase that happens to be in shakespeare. Then that phrase is marked as done.

      Let n be the size in characters of the target phrase. If n=1, then the complete works of shakespeare are obtained as soon as each of the letters of the alphabet have been typed at least once. You could do this in a few seconds on your computer keyboard. If n=2, then the complete works are obtained as soon as all the possible pairs of letters have been typed. The experiment in TFA has n=9 I think.

      As n grows larger, the time until completion grows exponentially. Once his expeiment is done, the case n=10 should take roughly 26 times as long (ignoring punctuation capitals and diacritical marks). Alternatively, it would require a cloud roughly 26 times bigger to do it in the same amount of time.

        You could prove that for the length of a work of Shakespeare (N), the amount of "monkeys" required to solve the problem in the same amount of time is 26^(N-9). Or, as it relates to the proverb, the solution to the equation has the time required to create a work of Shakespeare as infinite and the number of monkeys required to solve it in that time as infinite.

        Of course, that solution didn't require programming the monkeys. But it is extrapolatable out to an entire work.

      • This experiment, while fun, isn't exactly the infinite monkey experiment.

        Of course it is not. It is impossible to simulate an infinite amount of monkeys working for an infinite amount of time. Some concession has to be made to the fact that we have a finite amount of computing power.

        • This sort of concession misses the point. The "infinite monkey theorem" is about how wildly unlikely things are not the same as impossible things. Therefore you cannot discount the possibility that a thing happened or will happen just because it is very improbable to happen, if it was or is going to be subjected to an arbitrarily high number of "chances" to happen.

    If i'm understanding this, this isn't as cool as it seems. It seems like his 'monkeys' are just randomly creating words, and he matches those words against any word used in Shakespeare. If he gets a match, he marks that one as done. So, as some point one monkey made the word "be" and all of a sudden green lights all over the place.

    I think the original saying was how random and unique it would be for a solid set of strings to randomly create a whole piece of work _in one go_ . Not a word here, a word there, OMG 100% of Shakespeare words have been randomly created.

      Yeah, you got it right the first time. Despite the popularity of the idea that a million monkeys could randomly create the works of Shakespeare, It would take trillions of years for the monkeys to create the first few paragraphs. This is an obvious time-waster.

      • Trillions of years is generous. A million monkeys each making a unique 100 bit binary string every second would still take around 40 quadrillion years [wolframalpha.com]. This *vastly* underestimates the time of an actual paragraph, let alone multiple paragraphs, and it's still 40,000 times larger than the trillion years estimate.

        • What if you allow misspellings and word substitutions? I've been able to read ebooks just fine with all the steganography they've been putting in (either that, or pretty much every ebook I've ever read has had terrible editing...). Surely that narrows the problem space a little bit.

      • Ok, but how about this...

        The next letter in the target manuscript is 'F'... count the number of keystrokes until a monkey randomly types F. The next letter is 'l', type the number of keystrokes until an l is hit... and at the end multiply the numbers together...

        That sounds fairly reasonable to me.

        It's not that a million monkeys could randomly create the works of Shakespeare. It is that an infinite number of monkeys could recreate all of the work in the known world, including Shakespeare. The thing about infinity, is that it is really, really big. If the amount of resources thrown at a problem is truly infinite, all possible results just happen, no matter how improbable.

        The point of the saying is how mind-meldingly large infinite is, and how bad our minds are at comprehending the ramifications. This is one.

      • I'm probably the only person on /.who will point out that none of Shakespeare's works were written in paragraphs.

    • You nailed it. The problem becomes more difficult as the number of characters and words increases, for the simple reason that you have to go further without a mistake having been made. If something like a Bogosort [wikipedia.org] takes O(n*n!), I shudder to think how long recreating the works of Shakespeare would take, but that's the very point of the expression: to express the unlikelihood of a random set of occurrences leading to an outcome.

      • I always thought the expression was saying the exact opposite. I've always heard it used in a similar manner as "even a broken clock is right twice a day". That not every genius-looking outcome required genius-level input. In other words, rather than being about unlikelihood, it is about inevitableness.

        • I've heard it both ways, now that you mention it. "Put some monkeys in front of enough typewriters..." vs. "That's like putting monkeys in front of typewriters and expecting..."
