Of Weasels and weasling
As everybody should be aware by now, Denyse O'Leary is offering a prize for the original code for Dawkins' Weasel program which illustrates cumulative selection [1]. O'Leary's offer arises from people challenging Dembski's misrepresentation of the Weasel program, as he has misrepresented it yet again in a trivial non-id paper. To get some much needed perspective, read Joe Felsenstein's excellent article (and its follow-up) and those of Chris Mark Chu Carroll (here and here)
Seriously, arguing over whether Dawkins "weasel" program implements locking is a bit like arguing over whether the measuring cylinder in the Measuring Cylinder/Tap model of drug clearance is emptied by a tube or a bloke with a cup. Both are simplified systems that make demonstrating a concept easy, and do much the same thing.
The point is that a leading light of the cdesignproponentsits has spent an enormous amount of time critiquing a toy demonstration of selection, and can't even get the toy example right. Not only that, they can't admit when they were wrong. Heck, no one in the cdesign proponetsists can admit Dembski is wrong about a toy program, even when presented with video evidence.
Let's emphasise this again. It's a non-issue except for the way it highlights the determined cluelessness of cdesign proponetsists. To use the metaphor of the Measuring Cylinder/Tap model of drug clearance again, Dembski is effectively arguing that Dawkins said the measuring cylinder is emptied by a man with a cup in his book, but anyone can go to Dawkins original book, read how he set it up, and understand that Dawkins specified a tube. Dawkins doesn't specify how big the tube, or the flow rate of the tap, but it's sort of obvious and you can easily make an analogous system which demonstrates the same things that Dawkins does. Everyone understands except Dembski who then makes a convoluted argument over the whole thing (see www.evoinfo.org and read their "explanation" of Dawkins program if you have a spare half-hour of your life you don't mind wasting).
Now there is a video showing a measuring cylinder with a tube (metaphorically, see www.youtube.com/watch?v=5sUQIpFajsg (go to 6:15) for the real video showing the weasel program), Dembski goes "oh, Dawkins must have REALLY have used a cup in his book, then swapped to a tube for the video". Aside from the convoluted mentality involved in this staggering piece of "reasoning", it goes to the heart of the cdesign proponentists reliability.
When Dembski claims that Lenski et al., have "smuggled in information", explaining why they are wrong can get quite technical, but when they claim Dawkins has "smuggled in information", one can simply point to how deeply they have misunderstood Dawkins model, and if they can't get Dawkins right (after being told repeatedly, having it explicitly demonstrated to them and being shown a video), what hope is there that they got Lenski right.
For more information on Dembski's denial of the video evidence, see Dembski Weasels Out, for a wide compendium of Weasel programs old and new, including head to head comparisons of Dawkins version vs Demski's locking version see Weasels on Parade (note it took over 23 days for the Uncommon Descent people to come up with any programs themselves). To see where I completely reconstruct the output shown in Dawkins book, see here.
[1] Why doesn't O'Leary just ask Dawkins? The whole concept of running a competition to get Dawkins code instead of asking Dawkins is rather bizarre. While he may not have the original code, he can tell her how he did it.[2]
[2] People have asked Dawkins before. It no longer exists. Just like the AppleBasic programs I wrote to calculate stimulation-induced radioactive outflow for our laboratory. Used for years but vanished into the mists of time. Seriously, even if there was a disk around with AppleBasic finding a machine to run it and make copies would be an adventure in itself.

I thought Dawkins weasel was pretty neat, but I could play with that tap thing all day.

In my comments at UD I have repeatedly pointed out that by the apparent definition of latching and ratcheting, this is a basic property of all search algorithms other than blind random walk. That comment keeps being ignored - I wonder why?
@VM: It is pretty neat, and it can even be turned into a pretty cool game. See http://itatsi.com/
Flint · 30 August 2009
As I read it, the purpose here is an attempt to discredit the Unholy Text. The program is being treated as a competing scripture. Since the original source is known to be lost, demanding that it be produced shows that it must have been imaginary in the first place, and therefore there's nothing to be worshiped.
So we have competing understandings. Evolutionists focus on the power of selection, of which this is only one of a potentially infinite number of different valid illustrations. Creationists focus on the Word Itself, which is to be interpreted as needed to fit foregone conclusions. And if the Word Itself can't be produced, why, ANY interpretation is as good as any other.
Chris Hall · 30 August 2009
I first read about the weasel program when BD was whining, and I thought, I'll give that a go (I'm an out of work software developer who needs to keep my skills up to date), it took my about 35 minutes and I got the same results as reported with no locking. It took them 23 days? Are these people idiots? (this is a rhetorical question).
Joe Felsenstein · 30 August 2009
With respect to Dembski and Marks's paper, let me ask you folks one question. Suppose that D&M had actually gotten the latching issue right, and analyzed a non-latching version of the Weasel program. (They didn't get it right, but let's suppose). They would have computed their “active information” and come out with a modestly different number.
So would their paper then be OK? Would it then be a valid argument for ID?
I have argued (in the posts that Ian kindly refers to),
that their paper would not then be a pro-ID argument, but is just as consistent with theistic evolution, or even nontheistic evolution.
That is why I think the obsession of posters on the pro-evolution side with the latching issue is a waste of time, and plays into the hands of the ID people by, in effect, agreeing with them that the latching issue is the fundamental one. But I repeat myself.

I know that you weren't serious, but I still have my Apple //e, and it booted a disk the last time I tried it, so if you ever do need one, the adventure is already over. Chances are magnetic deterioration has corrupted most of the disks from that era, though.

I don't think I've seen it mentioned here, but Dawkins wrote another program to illustrate how evolution works. Does anyone remember his little insect creatures? He started with a little vertical line segment, and allowed it to evolve by branching (or not) at one end for several generations. It was easy to see how these figures (many of which started to resemble insects) could be selected: for "tall and thin," or "short and fat," or "highly branched," etc.

I think the whole paper is a little bit sloppily written: It lacks meaningful definitions, and carelessly recycles older articles. I understand that Dembski and Marks have some favourite quotes, which they used earlier, but couldn't they check the references instead of just cutting-and-pasting? For instance, Christensen's and Oppacher's article is called ”What can we learn from No Free Lunch? A First Attempt to Characterize the Concept of a Searchable Function”, not just ”What can we learn from No Free Lunch? A First Attempt to Characterize the Concept of a Searchable,” as Dembski and Marks have stated at least twice now...

This issue has certainly generated a lot of discussion.
At the end of the day -
1) Dawkins wrote a very simple program to illustrate a difference between random variation without selection, and random variation with selection.
2) It is very easy to write a similar program which illustrates the same thing.
3) The difference between random variation and random variation with selection can be illustrated in many, many types of models, computer, mathematical, etc, and is also intuitively obvious.
4) The program Dawkins wrote has nothing to do with the overall evidence for biological evolution.
5) The program Dawkins wrote has nothing to do with the overall credibility of Dawkins, because it is so easy to write such a program that it is the obvious default position to accept his claim that he did so, unless strong evidence to the contrary exists. Trying to attack the overall credibility of Dawkins by arguing that a trivially simple computer program he discussed over twenty years ago might not exist is not a convincing strategy, to say the least.
6) These points are obvious. Creationists are driven by an emotional agenda related to socio-political ideology and cult membership. They will say anything. They overlap strongly with the extreme political right, and use of the same obfuscation propaganda techniques is probably not a coincidence. It could represent mutual cross-inspiration, or parallel reasoning by psychologically similar minds, or both.

If anyone wants examples of the weasel program, I have a few posted at my home page:
http://home.earthlink.net/~matthewjheaney/
Note that the algorithm does not lock in successful hits (of a particular letter). Each generation is made from the genome that has the best score, computed over all letters. Yes, this means sometimes a letter changes from a hit to a miss -- but so what: other letters migrate closer to their targets.
a lurker · 1 September 2009
arachnophilia · 1 September 2009
man, it's been a while since i've seen that video.
it's actually obvious watching it that the program does not "lock" in correct letters, but allows for random mutations of any particular character, even if that character is correct.
but seriously. this whole thing is a big red herring attack on an incomplete and greatly simplified analogy for one small part of evolution. it's nothing to do with anything. even dawkins himself acknowledges that the program is not that good of an analogy for evolution, because the program is directed. it's just a simple demonstration of what why selection > no selection.

Has anybody examined the IEEE connection. I can understand somebody out of the culture war (or just plain sloppy) not checking the Weasel reference but the title is "Conservation of Information". Wouldn't that be a pretty ground breaking claim to make as I understand that nobody but creationists make this claim.
Either the reviewers were so out of their depth on the document (and could not be call peer-reviewers) or they are sympathetic to the ID cause.
One thing about this is that if it was a mistake, Dembski and Marks are a one trick pony with this (you must be smuggle information in to get a GA to work). How many more papers can they produce on the same narrow topic.

I think Latching is important. And the reason is not searching. It is the informationmining. Evolution in nature "don't lock right mutations". So in claiming that algorithm needs this kind of cheating talks about pre-coding.
So I don't wonder why ID:ist's use it all the time.
When program works without, it is just the shape of the "fittness landscape". And the argument of pre-coding is layed under unproven claim that "natural causes" cant in any relevant case generate any lawlike or even partially soft lanscapes. That "totally random" is only possible undesigned shape of fittness lanscape = Softening it is "precoding".
But in other hand: If we are talking complexicity, is'nt the random lanscape as complex as it can be? (Kolmogorov etc.-stuff.)

The original papyrus - no not the ones found in the desert, and certainly not the one found in your hotel room - those are just copies and copies of copies - but the *original* ones.

Plug in any string to represent survival slash reproductive success, i.e. "I can digest citrate."
Or enter a routine that changes the target string at random intervals. Selection will still move toward the new target faster than a random search.
Still, if ever "tempest in a teapot" was a propos, it's now.

Mike Elzinga · 2 September 2009
Yes, the trolls will continue to harp on “intelligence” in the computer program without the slightest awareness that these programs are toy models of the way Nature works. Evolution works within the laws of Nature.
That parts of a system randomly flip toward putting the entire system in equilibrium with its surroundings is so commonplace that one can draw general conclusions from this fact.
A gas coming into equilibrium with pressure changes in its surroundings does so because individual molecules randomly make energy and momentum exchanges with the surroundings until eventually the average energy and momentum of the entire gas is consistent with its surroundings.
That is what the random function performs in a computer program.
What the cdesign proponentsists are telling us is that it is “illegal” to use any knowledge of the physical world in our computer models of it. They want our programs to randomly thrash around with no point to them.
In other words, we are cheating if our computer programs actually reflect our understanding of Nature rather than matching the ID/creationists caricature of Nature.

Mike Elzinga · 2 September 2009
As long as we have a PERL example posted here, I guess I’ll give in to the nerd thing and make more explicit some of the allusions I had been making earlier.
When I had earlier given examples of radioactive decay in the presence of activation, a resistor discharging while it is also being charged, and a gas coming into equilibrium with its surroundings, I was giving examples that can be modeled on a number of different levels. The same can be said for the Measuring Cylinder/Tap Model that Ian linked to.
For example, radioactive decay can be modeled at the “stochastic level” in which individual atoms are randomly decaying. The result is an exponential decay curve that reflects a rate of decay that is proportional to the number of atoms left. Even beginning calculus courses discuss this differential equation.
When we place such a decay process in the presence of “activation”, we can often use an activation rate that is constant (say, due to background radiation).
So we now have a first order differential equation in which the net rate of change in a quantity, dQ/dt, is due to the fixed rate of “activation” R minus a decay rate that is proportional to the quantity remaining. Thus
dQ/dt = R – kQ.
This is a very easy equation – involving logarithms – and covered in elementary calculus. It is first order and requires that a constant be found from initial conditions. The answer is
Q(t) = (R/k)(1 – e- kt) + Q(0)e- kt.
If we can characterize a process as “decaying in the presence of a constant activation”, this will be the form of the equation governing the process.
In the case of Dawkins’ Weasel program, we see a process in which the “target string” represents the “ground state” of the evolving string. Random flips of characters in the evolving string in the “wrong” direction represent the presence of activation. We are actually observing this process at the stochastic level. Latching removes activation.
Note that the characters in that target string are irrelevant to the target being a ground state. That fact alone should eliminate any confusion about “intelligence being smuggled into the answer”.
Now the ID/cretinists have to justify removing any simulation of the process of decay toward a ground state. This misconception of theirs directly relates to their mischaracterization of Nature as a bunch of particles scattering randomly and elastically off each other (“In the beginning …”).
So the rebuttal needs to focus on what justification they offer for leaving out our understanding of physical laws in any of our research.
After all, we see how far their caricature of Nature has taken them in over 40 years of ID/creationist “research”.

Having dabbled with GAs myself, I have to say that ID acolytes attempts to criticise them are laughable in the extreme.
I always ask them, "Seeing as the outputs of some GAs defy deterministic analysis (for example, coding FPGAs via GAs produces some very weird, but functioning, results), how can the programmer have 'smuggled in the information'?" Indeed, the idea that engineers working in the private sector would waste time and money writing a GA to search for a solution when they know the optimal answer already is pure comedy.
Lately, ID priests and priestesses have been trying to dodge the issue entirely claim that the "algorithmic behaviour" of such simulations is proof of ID. This is usually followed up with some half-baked analogy linking DNA to computing languages. The goalpost shift is obvious, and I have no doubt that they'll continue to be shifted all the way back to the ultimate "fine tuned universal constants" get-out-clause.
All this is typical of a doctrine whose only aim is to create an intellectual vacuum into which to parachute theology. What a pathetic state of affairs.

I was in the audience.
The talk was about the history of the Physical Review, its exponential growth over the years, and the deterioration of the quality of most of the papers therein.
Near the end of his talk, Weisskopf said he made a back-of-the envelope calculation of how much the velocity of the right-hand edge of the Physical Review was increasing, as we think of it sitting on a long shelf.
With the numbers from the exponential increase in growth, he estimated the date in the future when the right-hand edge would be traveling faster than light.
Then he finished with, “But that’s ok, because there will be no information in it anyway.”
It brought down the house.

DS - your usual sloppiness. When did I say I worshipped a god or gods? Kindly cite the exact passage.
Do try and read without daydreaming. I keep my answers short to make it easy for the attention deficit folks of Evoland.
Mr Whinestine - a computer simulation is DESIGNED. The pt I was making.

Yea and the Thinker is a statue carved by an intelligent being. That is not evidence that humans were made by an intelligent being. Do try to learn some logic.
Now, why don't you worship the god who created pythons? You must live in constant fear of her rath.

I am puzzled as to why this guy believes anyone failed to understand his point.
The only point in response is that a simulation can be made of any process: evolution, stellar fusion, the orbits of planets, weather, chemical reactions, the
settling of dry particulate materials in storage, and so on ad infinitum.
The fact that a simulation can represent a process tells nothing about the origin of that process. Simply because a toy robot panda is built in a factory in China does not say that a real panda is built in a factory in China.
I am NOT puzzled as to why this painfully obvious response is not understood. Evobashers have been trotting out this limp argument for a long time and have been ignoring its blatant flaw for just as long -- it seems on the principle that looking thick doesn't matter as long as the barking continues.
It may be reasoning as silly as painting a tunnel opening in the side of a mountain and then showing a train coming out, but some folks cling to silly because they don't have anything else.
And, sigh, then we get the dodge that the entire Universe demonstrates Design ... maybe it does for all I know or care, but that notion is consistent with the Theistic Evolution standpoint, which any good evobasher firmly rejects.

Lol. The usual insistence that you-all don't understand an obvious pt. Orwell used to be annoyed with commies who wd take the attitude that you were only pretending not to agree that Stalin was creating a (survival of the fittest) Utopia.
Mike Elzinga. I do know an algorithm from a prog. I used to know how to find square roots on a slide rule but since I never need to, I've forgotten.
Funny you people are so worried by a "troll" (introlerant word).
Darwin ueber alles.

Well your god seems to want us to believe that pythons evolved. After all, they fit into the nested genetic hierarchy with all other snakes. This is true regardless of whether nuclear of mitochondrial genes are used as characters in the analysis:
MPE 24:194-202 (2002)
Computer programs designed by humans demonstrate conclusively that processes operating in nature are sufficient to generate information and increase complexity. Pointing out that the programs are designed is irrelevant. If you have any other point to make then make it. If not, then quit complaining about being labeled a troll.

Well, let’s move to where the troll can’t follow, and get back to the topic of this thread.
On a previous thread, Dave Thomas posted his nice program with some plotting that reveals some underlying patterns.
In an earlier post I showed the general equation that governs exponential decay in the presence of activation.
If you look at the equation I showed,
Q(t) = (R/k)(1 – e- kt) + Q(0)e- kt,
and note its asymptotic behavior when t approaches infinity, you will see this approaches a baseline of R/k.
So let’s rewrite the equation as
R/k – Q(t) = (R/k – Q(0)) e- kt.
Now we see that if we subtract the baseline, R/k, from the data, take the absolute value, and then plot this on a semi-log plot (log vs. linear), we get a straight line from which we can extract k. Having k and R/k, we can extract R.
Thus, if the process we are observing behaves like decay in the presence of activation, we can get the decay rate and the activation rate.
Mike Elzinga · 7 September 2009
Hmm, that link to my earlier post was wrong; it’s here.
Mike Elzinga · 7 September 2009
And let’s get the exponents right also.
Q(t) = (R/k)(1 – e- kt) + Q(0)e- kt.
It’s hard to get used to this KwickXML after using equation-writing software like MathType.

Okay, Darwinists, this will blow the whole scam wide open. Unlike you, I actually WATCHED "The Blind Watchmaker" (It had no blind watchmaker in it - typical Darwinist bait-and-switch). Not far into it, Dawkins says he "wrote a program." I'll give you a minute to take that in.
HE ADMITTED THAT THE PROGRAM WAS INTELLIGENTLY DESIGNED. Those of us who can determine CSI by inspection already knew that, of course. Not only did the program not arise by chance, as Darwinists say the eye, the immune system, and the flagellum did, but the computer it was intelligently designed on was itself intelligently designed - by men - at a computer factory. Furthermore, all the conditions for programming the computer were fine-tuned before Dawkins' intelligent design began!
The High Priest of Darwinism admitted he cheated and used ID to get a job done he claimed showed evolution. Same trick Darwin pulled. Like ideological forebear, like son!

Geez this is boring:
"Dawkins DESIGNED a program to model evolution and that means that he has proven INTELLIGENT DESIGN!"
"So if I make a science-fair volcano, that means volcanoes are intelligently designed, too?"
"Ah, you don't get it. Dawkins DESIGNED a program to model evolution and that means that he has proven INTELLIGENT DESIGN!"
"So if I make a science-fair volcano, that means volcanoes are intelligently designed, too?"
"But Dawkins himself has admitted it!
He DESIGNED a program to model evolution and that means that he has proven INTELLIGENT DESIGN!"
"So if I make a science-fair volcano, that means volcanoes are intelligently designed, too?"
And so on ...
