A One Line GA

Please post your software implementation of a GA that can be expressed in a single line of executable code.

Here’s mine:


A minimalist GA – Inspired by Allan Miller at TSZ

pop = Array.new(10) {“I AM APE-ISCH”}.map! {|ape| ape.dup}

The original population is copied and eliminated.

On May 23, the Talkrational database experienced a crash that left the post table broken.  Our Web Host, Arvixe, farted around for several days and let the last good backup of the database be overwritten with the borked version.

They’ve been singularly useless at recovering the database, but I have some slender hopes that we may be able to fully or partially recover the post table without their “assistance”.  osmanthus, one of our members who knows a lot of peeps in the forum tech world has reached out to some database experts who would like to try to resuscitate the database.

What A Code Is – Code Denialism Part 3

My intent here in these recent posts on the genetic code has been to expose the absurdity of Code Denialism. The intent has not been to make the case for intelligent design based upon the existence of biological codes. I know some people find that disconcerting but that would be putting the cart before the horse. No one is going to accept a conclusion when they deny the premise. And please forgive me if I choose not to play the game of “let’s pretend it really is a code” while you continue to deny that it actually is a code.

First I’d like to thank you. It’s actually been pretty neat looking up and reading many of these resources in my attempt to see whether I could defend the thesis that the genetic code is a real code. I admit it’s also been much too much fun digging up all the reasons why code denialism is just plain silly (and irrational).

That the genetic code is a code is common usage and if “meaning is use” that alone ought to settle the matter. But this is “The Skeptical Zone” and Code Denialism is strong here. But I’m not just claiming that it’s a code because we say it’s a code in common usage. I’m claiming it is a code because it meets the definition of a code. The reason we say it is a code is because it is in fact a code.

My first two posts have been on some of the major players and how they understood they were dealing with a code and how that guided their research. I’ll have more to say on that in the future as it’s a fascinating story. But for now …

Semiotic theory of ID

Upright BiPed has been proposing what he has called a “semiotic” theory of Intelligent Design, for a while, which I have found confusing, to say the least.  However, he is honing his case, and asks Nick Matzke

…these three pertinent questions regarding the existence of information within a material universe:

  1. In this material universe, is it even conceivably possible to record transferable information without utilizing an arrangement of matter in order to represent that information? (by what other means could it be done?)
  2. If 1 is true, then is it even conceivably possible to transfer that information without a second arrangement of matter (a protocol) to establish the relationship between representation and what it represents? (how could such a relationship be established in any other way?)
  3. If 1 and 2 are true, then is it even conceivably possible to functionally transfer information without the irreducibly complex system of these two arrangements of matter (representations and protocols) in operation?

… which I think clarify things a little.

I think I can answer them, but would anyone else like to have a go? (I’m out all day today).
