PT veterans may remember several posts from 2006, in a summer-long series of articles about Genetic Algorithms, Dawkins' Weasel, and Fixed Targets.
It's taken me a few years to get off my duff and write up a proper version for the
Skeptical Inquirer. I'm pleased to report that my article has been published in the
May/June 2010 issue.
The Good News: Several of my computer-generated diagrams have been professionally redrawn, and look splendid!
The Bad News: Besides the
"Web-Extra" sidebar about Solving Steiner Problems using soap films, the article itself, "
The War of the Weasels: How an Intelligent Design Theorist was Bested in a Public Math Competition by a Genetic Algorithm!", appears only in the print copy. You will have to go to your local newstand to get a print copy, or order one from the
Committee for Skeptical Inquiry (CSI) directly.
So, after almost four years, how has the ID community responded? Are they still fixated on Dawkins' "Weasel" demonstration? Do they still maintain that
all genetic algorithms require detailed knowledge of their solutions, just as the phrase "METHINKS IT IS LIKE A WEASEL" was the "fixed target" in Dawkins' 1986 exposition?
More below the fold.
Even though ID "theorist" Salvador Cordova got his hat handed to him by a Genetic Algorithm, the ID community by and large ignored the point of the entire series of posts, which was simply that most Genetic Algorithms (Dawkins' "Weasel" excluded) do
not require explicit descriptions of the answers it is hoped the algorithm will provide.
In the interim, there has been much hand-wringing by IDers over "latching" in the Weasel (see
this post by Ian Musgrave for a sampling).
Incredibly, after only a few years of concerted effort, the ID folks appear to have finally put together a
working version of the Weasel toy program as actually presented by Dawkins (including population sizes and mutation rates, golly gee whiz!) Look for the selection named "Proximity Reward Search".
As for Dembski and Marks, the law of "Same Garbage, Different Day" appears to be in play. They are
still painting all Genetic Algorithms with the "Need a Fixed Target - just like Weasel" brush, but any relevance to Dawkins or evolution science is becoming harder and harder to perceive.
If you read the ID articles, such as Luskin 's Ode "
William Dembski, Robert Marks, and the Evolutionary Informatics Lab Take on Dawkins' "WEASEL" Simulation in New Peer-Reviewed Paper," you would get the impression that this work is indeed about Dawkins and the Weasel:
The authors argue that Richard Dawkins' "METHINKSITISLIKEAWEASEL" evolutionary algorithm starts off with large amounts of active information--information intelligently inserted by the programmer to aid the search. This paper covers all of the known claims of operation of the WEASEL algorithm and shows that in all cases, active information is used. Dawkins' algorithm can best be understood as using a "Hamming Oracle" as follows: "When a sequence of letters is presented to a Hamming oracle, the oracle responds with the Hamming distance equal to the number of letter mismatches in the sequence." The authors find that this form of a search is very efficient at finding its target -- but that is only because it is preprogrammed with large amounts of active information needed to quickly find the target. This preprogrammed active information makes it far removed from a true Darwinian evolutionary search algorithm.
Here's the odd thing: the actual "peer-reviewed" paper that has the IDers so excited,
"Efficient Per Query Information Extraction from a Hamming Oracle",
makes no mention of Dawkins, or of his 1986 book the Blind Watchmaker! The article does claim that any use of simulation results (such as those used by NASA during evolutionary computation based development of wire antenna designs) within a Genetic Algorithm is an "Oracle," but then the only analyses presented are for the "Hamming Oracle", which assumes the
Hamming Distance (the number of positions at which two strings differ) as a figure of interest.
While this "Hamming Distance" is obviously targeted at Dawkins and the Weasel, it has nothing to do with algorithmic solutions to antenna design, or to Steiner's Problem, for example.
Richard Hoppe has a relatively recent post,
"Another smackdown of Dembski & Marks" that discusses the ID crew's aggressive use of Smoke and Mirrors.
If you haven't yet read about the Steiner Problem, or its solution with Genetic Algorithms, consider getting a copy of the new Skeptical Inquirer!

I just wanted to thank you for your original articles; they have stayed with me all this time. I never took any courses on GAs (I'm an EE/CS professional), but that example really crystallized a lot about them for me, especially what makes a "good gene" for purposes of GA and the sort of problems they can solve. I still haven't had the chance to employ them yet -- I have a few candidate ideas -- but I have your article bookmarked for when I do.
Mike Elzinga · 19 April 2010
I’m quite sure it is not evident to the ID/creationist crowd, but their continued confusion about Genetic Algorithms and Dawkins’ “Weasel” program is directly related to their continuing misconceptions about thermodynamics; the 2nd law in particular.
A simple change in perspective turns “Weasel” into a condensed matter program in which a gas of interacting atoms are condensing into their mutual potential wells. Depending on how strong the “latching” is determines the relative sizes of the mutual potential energy wells and the kinetic energies of the atoms.
Weak or no “latching” is analogous to shallow wells from which atoms can be easily kicked out. It is somewhat like a quasi-liquid stage. Condensed collections can form, but they are approaching a state of being ephemeral in that they can be broken up as others form.
Deepen the wells, and we have a situation in which the mutual potential energy wells are comparable to or larger in magnitude than the kinetic energies of the atoms. We enter a viscous stage or a solid-forming stage.
The fact that the program selects the parent that gets to reproduce simply reflects the lower energy atoms that remain after other atoms or photons or phonons carried off part of their kinetic energy. These remaining atoms become the collection from which the condensate will ultimately form; but there is nothing preventing any of them from picking up additional energy and being kicked out and replaced by other atoms with less kinetic energy.
There are ranges within which one can set the “latching” strength that result in an “exponential decay” in the difference between the number of “unfit” (uncondensed) offspring (atoms) and the ideal organism (condensed atoms) for the given environment (potential well configuration). This results in a straight line on a semilog (log-linear) plot.
The “Weasel” program is also analogous to a radioactive decay of a collection of atoms in the presence of activation.
There is nothing about Genetic Algorithms or Dawkins’ little program that has to be expressed in terms of “information” or “order.” The “target string” could just as well be a string of random numbers giving the shape of the final potential well configuration into which the atoms condense or it could represent the ground state of the decaying atoms.
In other words, real scientists use what they know about Nature rather than assume, as the ID/creationist crowd does, that it is all chaos and uniform random sampling on essentially infinite solution sets.

Mr. Elzinga,
It seems that you are putting the cart before the horse.
You seem to be asserting by your above analogy that biological activity is the product of the emergent properties of a large complex of atom and therefore can be analysed in the same way a physicist would analyse atomic activity.
Yet the white elephant is how and why do certain large collections of atoms come together in a myriad of configurations, which exhibit extraordinary properties, while other large collections of atoms do not?
Until this mystery is solved, how can you assert that biological activity is by and large analogous to atomic activity but simply on a different scale?
Isn't it logical to assume that the emergent properties of this large configuration of atoms we call biological organisms would necessarily be different than the non-biological configurations of atoms?
So then, how do we know that there must not be a dichotomy between the two?
BTW, let me make the (apparently necessary on this blog)call-out on my remarks. I am asking the above in earnest, as a layman.
Vince · 20 April 2010
Stanton · 20 April 2010
First of, Steve P., you are misusing your metaphors: a "white elephant" is an object that is both valuable, and a dreadful waste of money to maintain, you're thinking of "the elephant in the room," which is an obvious and dreadful problem no one dares to mention.
The problem with your assessment is that, the elephant in the room you're talking about does not exist. As far as scientists have observed, the atoms of biological entities behave in the exact same manner as to atoms of non-biological objects, especially since organic molecules of a biological origin behavior just like organic molecules of a non-biological origin, as well as the fact that people have observed organisms taking up atoms from non-biological sources for over a century. I think you are conflating biochemistry with atomic behavior.
DS · 20 April 2010
Actually, the so called "elephant in the room" is not something that is unmentioned or unknown, it is simply replication. Once systems can replicate, cumulative selection can occur, whether the replicators are alive or not. Molecules can replicate, therefore they can undergo selection, therefore they can become more complex over time. It really is that simple, whether the elephant is white or purple.

Steve P. asks, "how and why do certain large collections of atoms come together in a myriad of configurations, which exhibit extraordinary properties, while other large collections of atoms do not?"
A hundred years ago, when scientists believed cells were full of a mysterious substance they called protoplasm, that was a legitimate scientific question. Before it was possible to magnify the innards of cells enough to see their molecular structure, it made a certain amount of sense to treat the goo inside cells as different from ordinary chemicals.
The realization that the chemistry of living things obeyed the same laws of physics as inanimate minerals largely came from better tools for studying very small objects like molecules-- tools like x-ray crystallography and electron microscopes.
After 1953, when it became obvious that DNA has a regular crystalline structure just as much as salt does, there was no longer any good reason to look for "extraordinary properties" in living cells. The science of molecular biology was born, based on the premise that molecules in living cells would obey the same laws of chemistry and physics as any other chemicals.
If the day comes when scientists discover molecules in living cells don't obey the ordinary laws of chemistry and physics, you may be sure they will rush to uncover the new laws of nature. But don't hold your breath. The fields of molecular biology and biochemistry have gone from strength to strength. It's very unlikely they will run out of exciting hypotheses to test in our lifetimes.

Mike Elzinga says:
If you want to show a “barrier” to the phenomenon we call life, then you have to show that scientifically. You can win a Nobel Prize for doing so.
People often say something like that. But in which Nobel Prize category would this putative prize be given? The closest category seems to be "Physiology or Medicine". But that seems to be a real stretch!

Steve P. · 22 April 2010
Mr. Elzinga,
I do think there is a barrier and that barrier has something to do with light. Literally.
IMO, life is the culmination of the integration of light with matter so it is not only utilized by the human body but more than likely is central to its function.
The thought of light came to mind from my work in nanotextiles. We are currently working with FIR (far-infra red) yarns that are produced by mixing ceramic powder, which emits FIR light. I have also just completed a development with Celliant (www.celliant.com)which uses an even more advance mixture of ceramic materials.
Second, my experience with chi also informs me that this intuition is not pie-in-the-sky. I was able to get 'in the zone', which activated my chi. The best way to describe the experience is it resembles a rippling wave moving right to left in a circular pattern through the body.
Finally, my theistic philosophy also informs me about the barrier, since I believe the soul is also a form of light (we are created beings so even our soul must be natural; only the trinity resides in the uncreated realm). Yes, it can't be detected now but in time science will come up with a way to detect this elusive human perception.
So, if I'm gonna win that Nobel, this is where I would start. And I would also want to figure out how information ties light to matter (this is where Dembski and Marks come in).
Sure, these may just be musing from a spaced out, God deluded layman. But then again...

I don't suppose that there's any point in saying that Steve P might as well have said something like: "The flimflam urgle of the needlenardlenoo..."
It doesn't actually mean anything. Where it purports to describe reality, and this description can be parsed, it is grotesquely and bizarrely false to fact.
A rippling wave that moves "right to left in a circular pattern through the body"? How can a circular pattern be also left to right?
The soul is a form of light? A soul is a form of electromagnetic radiation of wavelength between 400 and 700 nm? What, so a lightbulb's a soul generator, then?
Life is the integration of light and matter? Leaving aside the fact that this is gibberish on the face of it, at best an impossibly vague piece of mystical handwaving that says absolutely nothing, how does it explain life that lives in permanent total darkness, in caves or the ocean depths?
And this is to leave aside completely the fact that there is no actual, you know, evidence that chi or souls exist at all, far less that there's a "barrier" (between what and what?), or that the trinity "resides" someplace ("Trinity" implies the Christian God. I thought he was supposed to be omnipresent) or that there's an "uncreated realm", (which would appear to be a denial of the idea that God created everything).
It seems to be a muddled personal mythology, slightly flavoured with non-western terminology, but wholly nonsensical and completely severed from any consideration of reality whatsoever.
So I'll take option A. These are musings from a spaced-out deluded layman. I'll leave God out of it, though. If he created the Universe, he's a damn sight more coherent than this is.

Of course its all gibberish to you all.
But the question is, have any of you ever learned chikung, or shangkung? Have you ever done yoga breathing techniques? have you evaluated if/how they affect your body? Have you done any self-therapy using a portable low voltage electrical stimulation device promoted by hospitals (here in Taiwan anyway),which substitutes for physical therapy sessions and evaluate its effects on your body?
No, didn't think so. But you all don't need to do that. Because you already know western medicine is light years ahead. Nuff said.
And the second question still remains, have any of your actually bought and used a Celliant product and evaluated whether the FIR light emitted from the nano-ceramic fibers does anything to your body? Does it relieve pain as the marketing claims say, does it actually increase blood circulation?
Have any of you ever verified through a special device, which has a sensor attached to your skin, and allows you to actually see (through a connected monitor) the dramatic difference in the speed with which blood cells travel through capillaries when an FIR infused diamond powder plate was placed anywhere on your body?
Didn't think so, either.

What some proponents of "traditional/alternative medicine" forget is it is substantially empirical. Ayruveda the traditional medical practice of India - if you forget the talk about Humours/Doshas/Phlegm etc - also categorized a vast collection of herbs with detailed indications, included surgery (which suffered a setback during the Buddhist centuries around the cusp of BCE/CE because of the Buddhist abhorrence of dissecting corpses.

There have been some useful drugs or medicines that came from Chinese traditional medicine - artemisinin, for example, which is a genuinely effective anti-malarial, and some say digitalis as well. Salicylic acid, though "willow-bark" was known to European medicine also. Possibly others.
But there's an enormous amount of nonsense, too. For example, the artemisium plant that contains small amounts of the active antimalarial is only one of over 250 plants, said to be effective against fevers, that were double-blind tested, and it was the only one that did better than placebo. And of course traditional Chinese herbalists did not do anything more than dry the plant parts they used, so the active component was not isolated. Nor did they possess the chemistry to synthesise it, which meant that in traditional medicines it was expensive, of varying effect, in short supply, and mixed with both neutral and actually toxic other substances.
Chinese chemists did the refining, the testing and the synthesising, using the sciences developed in the west, and what do you know? The results worked far better, far more reliably and with far fewer side-effects, and the dosage could be calculated rather than guessed at.
Sorry. Western medicine for me, if I need medicine. It may not work, but it's the way to bet.
Dave Luckett · 23 April 2010
I forgot to say, Steve, that's because Western medicine is light years better, and you are peddling woo and lala.
harold · 23 April 2010
Dave Luckett -
Digitalis was almost unequivocally discovered by "western" medicine through the study of English traditional medicine. Knowledge of its effects may be present in many other traditional systems, for all I know.
http://en.wikipedia.org/wiki/William_Withering
Of interest, the somewhat effective traditional way of managing cardiac failure involved a complex mixture of herbs, of which only digitalis was useful for this particular condition, similar to the Chinese case you mention.
Traditional systems tend to lack not empiricism, which is often if not always present, but rigor, organization, and peer review.
I will note that, in primitive conditions when an exact diagnosis can't be made, putting together a "cocktail" of plant products empirically known to have medicinal effects may not have been the least logical approach, in some cases.
Obviously, some traditional medicine systems may well sometimes offer something that is better than either nothing or placebo. It's also worthwhile to study such systems for anthropological and sociological reasons.
None of this changes the fact that "western" medicine is usually the most effective, and virtually always the system that has the strongest tradition of objective scientific testing of claims.

One of the areas I worked in for many years was research and development on infrared, Schottky barrier, CCD imagers. I did both extensive theoretical work and experimental work on these. We can predict and tailor the behaviors and characteristics of these devices under all sorts of conditions; so IR is not at all strange to many of us in physics.
These devices are used in IR telescopes and satellites, and they also have extensive uses in the military and in other classified applications. They have industrial and medical applications as well.
I could imagine what some of these woo-woo New Age “philosophers” would say if they saw the images produced by these devices. I suspect it would be quite similar to their excitement over Kirlian photography and the photographing of souls and auras.
But it is just interesting and well-known physics all the way down.

I take it that, being rational people, if you were suffering from a medical condition and were offered a choice between a "mainstream" medicine of exactly specified concentration, known to be effective from double blind testing, with a voluminous literature on toxicity and effectiveness and the incidence, type and severity of side-effects, or a traditional herbal preparation, said to be effective, but with none of those characteristics, you would choose the former.

The point of bringing up chi, FIR light, information, and soul was to show potential markers that could point the way to elucidating the nature of the barrier existing between life and non-life.
Mr. Elzinga asserts there is no barrier between life and non-life, only degree of complexity; an [emergent]property of matter as it were.
If this is the case, we should see various life forms prevalent in the universe, not necessarily justcarbon/water life as on earth.
It should be possible to find iron life on Mars for example or methane life on Neptune, or any of numerous combinations of elements in their solid, liquid, and gaseous forms. The probablistic resources of these numerous elements are such that it should be inevitable matter would find a variety of paths to complexity.
It seems the whole point of SETI and part of NASA's mission is to in fact confirm the probability and inevitability of matter to complexify and lay to rest the idea that life is a special condition of matter, not intrinsic to it.
Yet, we have spent billions in searching our solar system and the cosmos to for signs that would confirm 'life must be common', without success.
The logical conclusion we can draw from the dearth of confirming data in favor of a non-barrier conclusion is that life indeed has a special component responsible for a clear categorical difference between life and non-life.
Repeatedly chastising Dembski and Marks for seeking to elucidate information as a contender for that special component is hardly being scientific but rather dogmatic and ideological.

I recently had my plumber Steve over to my house to do a minor repair in my basement utility room. While he was making the repair, he noticed a quarter on the floor near the water heater.
"How did that quarter get there?" he asked.
"I'm not sure, I suppose it fell out of someone's pocket and ended up there. Maybe when someone was taking something out of their pocket, the quarter got dragged along and fell out."
My plumber was unconvinced. "The fabric of your pants presents a barrier to coins leaving spontaneously, and it is very unlikely to find a quarter by a basement water heater. There must be some purpose for that quarter to be there."
"Look," I said, "coins fall out of people's pockets all the time. It's simply a consequence of the way pockets are designed and used."
"If that's so, there should be lots of coins everywhere." He then looked more carefully around the water heater; no other coins. He expanded his search, looking near the furnace, the air conditioning unit, and the water softener. Still no other coins.
Steve looked up from the water softener and told me, "According to you, coins fall out of people's pockets all the time. I've just spent a fair amount of time looking very carefully for other coins and found none. This disproves your 'just-so' story about coins falling out of people's pockets. I doubt there are even any other coins in the house; if there were, I would have found some evidence of that by now."
"Seriously? I'm pretty sure that if we looked through the entire house, we'd find coins in the sofa under the cushions, on the floor in the kids' rooms, and a few other places."
"Nope. There's a barrier to coins leaving pockets on their own; there's no point in even looking for other coins, because the only coins you'll find were placed in their current locations deliberately."
"OK, Steve, have it your way. Can I pay you for the job in pennies?"
EPILOGUE: Steve the plumber went on to get some specialized training and now works at the Center for Scrubbing and Cleaning at the Dishwasher Institute. He is currently involved in studying intelligent placement, the theory the inappropriate debris is deliberately placed in automatic dishwashers to cause their failure.
