Second Law auf dem Instituts-Server http://www.math.utep.edu/Faculty/sewell/articles/article.html und<br />

Appendix D: Can ANYTHING Happen in an Open System? seines Buchs The<br />

Numerical Solution of Ordinaty and Partial Differential Equations, John Wiley &<br />

Sons (http://www.math.utep.edu/Faculty/sewell/articles/appendixd.pdf). Aus seinem Beitrag "A Second<br />

Look..." hier nur ein kurzer Auszug (er setzt sich auch in diesem Essay für den<br />

intelligenten Ursprung des Universums und des Lebens ein):<br />

"Science has been so successful in explaining natural phenomena that the modern scientist is convinced that it<br />

can explain everything, and anything that doesn't fit into this model is simply ignored. It doesn't matter that there<br />

were no natural causes before Nature came into existence, so he cannot hope to ever explain the sudden creation of<br />

time, space, matter and energy and our universe in the Big Bang. It doesn't matter that quantum mechanics is based<br />

on a "principle of indeterminacy", that tells us that every "natural" phenomenon has a component that is forever<br />

beyond the ability of science to explain or predict, he still insists nothing is beyond the reach of his science. ...<br />

[Nach Hinweis auf den 2. Hauptsatz der Thermodynamik zur Wahrscheinlichkeitsfrage] But one would think that<br />

at least this would be considered an open question, and those who argue that it [the evolution of Life] really is<br />

extremely improbable, and thus contrary to the basic principle underlying the second law, would be given a<br />

measure of respect, and taken seriously by their colleagues, but we aren't.”<br />

Was G. Sewell's Beiträge auf dem offiziellen Server seines Instituts und seiner<br />

Universität anlangt, so liegen hier noch einige wichtige Sperrungsaufgaben für<br />

Herrn Kutschera und Mitarbeiter bereit, ebenso im Falle von Michael J. Behe<br />

(siehe unter http://www.lehigh.edu/~inbios/faculty/behe.html). Beim nächsten Autor, Robert J. Marks<br />

II, haben das allerdings schon andere für sie besorgt.<br />

William A. Dembski and Robert J. Marks II (2009): Conservation of<br />

Information in Search: Measuring the Cost of Success (in press).<br />

Abstract: Conservation of information theorems indicate that any search algorithm performs on average as well<br />

as random search without replacement unless it takes advantage of problem-specific information about the search<br />

target or the search-space structure. Combinatorics shows that even a moderately sized search requires problemspecific<br />

information to be successful. Three measures to characterize the information required for successful search<br />

are (1) endogenous information, which measures the difficulty of finding a target using random search; (2)<br />

exogenous information, which measures the difficulty that remains in finding a target once a search takes<br />

advantage of problem-specific information; and (3) active information, which, as the difference between<br />

endogenous and exogenous information, measures the contribution of problem-specific information for<br />

successfully finding a target. This paper develops a methodology based on these information measures to gauge the<br />

effectiveness with which problem-specific information facilitates successful search. It then applies this<br />

methodology to various search tools widely used in evolutionary search.<br />

(P. 1 of pdf draft:) "Such [novel] information does not magically materialize but instead results from the action of<br />

the programmer who prescribes how knowledge about the problem gets folded into the search algorithm.”<br />

William A. Dembski and Robert J. Marks II (2009): The Search for a<br />

Search: Measuring the Information Cost of Higher Level Search (in press).<br />

Abstract: Many searches are needle-in-the-haystack problems, looking for small targets in large spaces. In such<br />

cases, blind search can stand no hope of success. Success, instead, requires an assisted search. But whence the<br />

assistance required for a search to be successful? To pose the question this way suggests that successful searches<br />

do not emerge spontaneously but need themselves to be discovered via a search. The question then naturally arises<br />

whether such a higher-level "search for a search” is any easier than the original search. We prove two results: (1)<br />

The Horizontal No Free Lunch Theorem, which shows that average relative performance of searches never exceeds
