Paul, I’m not the one whose evaluation of ev has gone from it represents reality, to it represents a tiny fraction of the evolutionary landscape to it represents a stylized model of mutation and natural selection.
That is neither a yes nor a no.
Paul, you have just changed you position on what ev does. I have said that the weight matrix always recognizes a binding site no matter how long the genome.
If by "recognizes" you mean matches, that is not correct.
When you set any of the weight counts to zero, all you are doing is not including that selection condition in the evolutionary process.
I presume you mean mistake counts. That is correct, setting a mistake count to zero removes that selection pressure, rendering Rcapacity et al moot.
Paul, there is no gene in ev, there is just a region of the genome that you set aside to evolve binding sites.
The weight matrix and threshold are referred to as the gene.
If you set the weight condition for missed sites to 1, and spurious sites inside and outside the binding site region to 0, you will evolve the binding sites where they should be according to the model but still have spurious bindings elsewhere on the genome.
I presume you mean mistake count. You are correct.
Here is another example: G=100,000, binding site width=4, weight width is 3, Rfrequency is 13.61, Rcapacity=8, gamma=8, mutation rate=1 per genome per generation.
Missed sites/spurious gene/spurious non-gene/Gens convergence PC
1/0/0/1
0/1/0/54
0/0/1/2192
Here is a case where Rfrequency is much greater than Rcapacity.
Rfrequency and Rcapacity are irrelevant here. They only matter when attempting to evolve creatures who distinguish binding sites from other sites, that is, when all three mistake counts are positive. Let me try to make this simple:
Measures of information capacity, requirement, and current state are only relevant when distinguishing binding sites from other sites. If you are not trying to distinguish them, then the amount of information required to do so is irrelevant.
Ev has no problem locating the binding sites where they should be when that weight factor is set to 1, ev has no problem eliminating spurious binding sites in the gene region when that weight condition is set to 1, and ev has no problem eliminating spurious binding sites outside the gene region when that weight factor is set to 1.
Correct.
This is all done in a case with Rfrequency is almost twice the value of your Rcapacity value.
See above.
The ev computation cycles through a mutation/selection process. When you have too many selection conditions on too long of a gene, evolution stops.
You have not demonstrated this.
Eliminate 2 of the 3 selection conditions and ev starts evolving that portion of the genome.
Correct.
When you say “gene does not distinguish the binding sites from the rest of the genome”, what are you talking about?
See above.
If you are talking about the weight matrix which represents the binding protein, the above example once again shows that the weight matrix has no trouble locating binding sites whether they are missed sites where they should have occurred or spurious sites where they should not occur no matter how large the genome is.
That is not what I am talking about.
And ev can’t do all three selection conditions when the genome becomes too long.
...
I just did an example above with a genome length of 100,000 and a binding site width of only 4 bases.
But you did it with two of the selection pressures turned off, so your experiment has nothing to do with the first statement you made here.
Even the elimination of the spurious binding sites in the non-binding site region of the genome took only a couple of thousand cycles. I believe you can do a genome length of 3 gigabases and get convergence if you only have a single selection condition, but more than one selection condition and you can only evolve tiny nonrealistic length genomes.
Please demonstrate this claim.
Paul, it is not Rcapacity which stops ev from converging, it is the conflicting selection processes that stops evolution.
Please demonstrate this.
Your Rcapacity concept is useless for estimating which cases will converge unless you include all three selection conditions in ev.
No kidding, Sherlock. That is because Rcapacity is
completely irrelevant unless all three selection pressures are present.
You know more about your string cheese theory of evolution than you do about ev. Setting a weight to zero is simply eliminating that particular selection process.
Which renders the information measures meaningless, as Kjkent said.
