The problem is, I have many examples of things not designed that fall under Dembski's UPB.  Would you like a list of them?

The Bacteria Flagellum
Human Being
Monkey
Whale
Banana
Pine Tree
etc...

You cannot demonstrate that any of these above items were derived by unintended contingent mechanisms.  It is uncertain how these items were derived since we lack the causal history.  None of these examples can be used without making a leap of faith.

It is not my intention to show a proof of anything. You must support your claim  (Remember that from the thread you posted?)

We have your words two posts back claiming these were examples that rare materialistic events falsify the concept of a UPB.  Now since you cannot show the causal history you retreat.

BTW, the snowflake does meet the requirements and is a false positive.

The narrative is interesting, but objective proof requires numbers.  Walk me through the numbers because I suspect these events are not nearly as rare as you would have us believe.

BTW, can you settle a bet:

Which sentence has more specified information, according to Dembski?

A. The Capital of WA is Seattle.
or
B. The Capital of MS is Seattle.
or
C. The Capital of MS is Jackson.

Gee, I don't know, RF, what are the numbers you apply to something that "seems" designed?  It include SC yet you are seperating it out. How odd - and yet predictable.

Game over, checkmate. You lose.

One easy number to apply to design is the UPB.  If we were to investigate all chance hypotheses that we can identify for an event or thing of unknown causal history and we were to find the combined probability of it and all non-detachable permutations of the event were less than the probability associated with the UPB then we would reasonably conclude the event or thing was designed.

Too bad the UPB is meaningless.

Too bad you were unable to make good on your claim to demonstrate with an actual case of a rare event that you can falsify a UPB.  Too bad also that a few posts back you even very reluctantly admitted they are valid in probabilistic analysis in cryptography.  There is very definitely a losing side of this debate and it is very clearly not me.

I gave many, I even gave an example that a fellow ID'ist gave.  You prefer not to see what is true, only what you believe.

A recent review of the ev program (one of the examples you seem to consider valid) by Baylor Professor of Electrical Engineering Dr. Robert Marks (currently researching the capabilities of computing including EA systems) along with Dr. William Dembski  demonstrated that the ev evolutionary algorithm imports so much information that the actual search need only to find 8 bits of information. In other words, pure blind search of the sample space, once confined by all the smuggled in information, could potentially find the solution in fewer than 256 iterations, hardly a "rare" occurrence.

The only thing Marks and Dembski demonstrated was their own abject incompetence (not to mention colossal arrogance).

As far as the UPB, Lloyd pointed out that the universe has had time to do ~10120 logical ops on ~1090 bits.
But the foundations of the concept of probability say the probability of any unique event remains subject to the ideas of good ol' Reverend Bayes, which merely sinks the alleged probability distributions that one is claiming determine the probability, rather than demonstrating the UPB has actually been exceeded. Which is a different way of saying what daedelus2.0 seems to have been saying.

Meanwhile, is R. Faith claiming that the actual probability of a purposeful design is undeterminable? Or not? if not, he is welcome to take any known purposeful design and calculate for us it's probability -- its "absolute, ultimate, from-the-perspective-of-the-universe" probability. And do it while ignoring Rev. Bayes.

Anyone is capable of making slight errors from time to time.  I certainly make my share and I suspect you do too.  The article is several months old now and revisions have been made to the original results.  Have you reviewed the revised results?  If so do you still find errors?

Here is the revised report: A Case Study with ev

More on the theory of the computations.

Probability applies to chance events.  Purposeful design is not chance so it is not that one can't determine the probability of purposeful design, it just makes no sense to speak of it that way. There is uncertainty in the results or performance of a design against the intended function but it makes no sense to speak of the probability of design.  This is why the method is "Chance Elimination".  One looks at the probability that the event could have been generated by the set of chance hypotheses but not the design hypotheses.

The concept of a UPB acknowledges that there are limits on the amount of resources available to act on chance and generate chance outcomes.  The idea or claim that there is no UPB is equivalent to claiming there is no limit on resources and this is simply false.

Why not? You could set up an experiment giving a disparate set of individuals the same task, say, designing a paper airplane that will fly 20'. You could separate them by age, or occupation, or species or whatever and use the information gained to calculate the probabilities of a certain individual performing the design function.

You have to know something of capabilities and process to determine if there were intended function. Even the definitions are inadequate: I suppose Design is an intentional arrangement of parts and I guess you would define Intelligence as an capable of thinking like a human. It's not helpful. Even a  functional design can happen by accident - unintended design. Or by a combination of design and chance. Without knowlege of intent and process the whole concept of Intelligent Design is useless.

No fair. In assessing which hypothesis is more probable you have to weigh the design hypothesis against the current evolutionary hypothesis. Evolution has the observed phenomenon of selection and genetic drift operating through a process of genetic recombination. Every fossil found, every genetic history teased out, every regulatory gene/phenotype interaction changes the probabilities of the evolutionary hypothesis. Without a proposed process or even an identified timeline for a designed feature you can't begin to make a comparison as to whether evolution or design is more likely. Until you come up with some empirical design evidence the most likely explanation for biological diversity is the evolutionary hypothesis. If you feel that you have proved to your own satisfaction that the current evolutionary synthesis is statistically inadequate to explain the present diversity of life then the default is don't know.  And to be considered science "don't know" will always default to some testable naturalistic hypothesis.
