From: BARRY MCMULLIN <75008378@DCU.IE>
Subject: Rosen's paradox (mostly...)
Hello lifeforms everywhere:
I've just been scanning a rather old paper by Robert Rosen (which
demonstrates, incidently, that ALife is not as recent an invention
as some may think):
-------
``On a logical paradox implicit in the notion of a self reproducing
automaton''
Bull. Math. Biophysics 1959, V21, pp.387--394
-------
In it he makes a very general argument to the effect that an SR-automaton,
in von Neumann's sense, is paradoxical. I am aware of a parenthetical
rebuttal by E.F.Moore (Essays in Cellular Automata, pp.191--2); and also
a full paper rebuttal by B.S.Guttman (Bull. Math. Biophysics, 1966, V28,
pp. 191--4), but do not know of any other explicit comments on the issue
(except, perhaps, a very offhand remark by Rosen himself, somewhere in
the ``Theoretical Biology and Complexity'' book...).
So to my questions:
o Does anyone know of other published comments on this?
o Does anyone have any views on the status, now, of Rosen's
argument---i.e. are either or both rebuttals given above
satisfactory?
o More specifically: my reading of Rosen's argument is that it
relies on a claim that a mapping is only well defined if its
range is stipulated more or less independently of anything else;
whereas, it seems to me to be satisfactory if the domain is
specified independently, *and* there is some (effective?) procedure for
finding the image of any element of the domain (thus implicitly,
but effectively, specifying the range). And on the latter
view, provided we have some mechanism for establishing
equality of our mappings, which does not rely on directly
comparing their ranges, then SR (in the von Neumann sense)
need not involve any kind of paradox. I think I must be missing
something obvious here, because this ``rebuttal'' is much less
sophisticated that those offered by Moore or Guttman---in effect
I can't see how Rosen's argument gets off the ground in the
first place. Can anyone clarify this for me?
Replies welcome either through Alife digest, or direct to me
(in which case I will summarise back to the digest).
--------
And while I'm writing to Alife digest, two other small, unrelated,
comments:
o I seem to remember that, in the proceedings of the first Alife
workshop, there was a suggestion that the bibliography given there
might be made available in machine readable form (possibly even
BiBTeX format?). Anyone know if that ever happened?
o For anyone doing camera ready copy for ECAL-91: I have hacked up
a LaTeX .sty file for it, which I'll happily copy to anyone who
wants it. However, this has not been seen (never mind approved!)
by anyone officially connected with ECAL-91, so caveat TeXToR...

PPSN 92
Parallel Problem Solving from Nature
Free University Brussels, Belgium
28-30 September 1992
The unifying theme of the PPSN-conference is ``natural computation'',
i.e. the design, the theoretical and empirical understanding, and the
comparison of algorithms gleaned from nature as well as their
application to real-world problems in science, technology, etc.
Characteristic for natural computation is the metaphorical use of
concepts, principles, and mechanisms explaining natural systems.
Examples are genetic algorithms, evolution strategies, algorithms
based on neural networks, immune networks, and so on. A first focus
of the conference is on problem solving in general, and learning and
adaptiveness in particular. Since natural systems usually operate in a
massively parallel way, a second focus is on parallel algorithms and
their implementations.
The conference scope includes but is not limited to the following topics:
Physical metaphors such as simulated annealing,
Biological metaphors such as evolution strategies, genetic
algorithms, immune networks, classifier systems and neural networks
insofar problem solving, learning and adaptability are concerned, and
Transfer of other natural metaphors to artificial problem solving.
Objectives of this conference are 1) to bring together
scientists and practitioners working with these algorithms, 2) to
discuss theoretical and empirical results, 3) to compare these
algorithms, 4) to discuss various implementations on different
parallel computer architectures, 5) to discuss applications in
science, technology, administration, etc., and 6) to summarize the
state of the art.
For practical reasons, there will be both oral and poster
presentations. The way of presentation of a paper does not say
anything about its quality.

\section{ARTIFICIAL LIFE II VIDEO PROCEEDINGS}
\end{center}
This video-tape constitutes the Video Proceedings of the Second
Artificial Life workshop, held in Santa Fe, New Mexico, February 5-9,
1990. It is meant as a companion to the printed proceedings of that
workshop, entitled {\em Artificial Life II}, which are also available
from Addison-Wesley. This tape is intended primarily as a record of
some of the computer simulations and other dynamic, graphic, or otherwise
visually oriented material presented at the meeting in Santa Fe.
\section{Artificial Life}
Artificial Life (AL) is a relatively new field of scientific inquiry,
standing roughly to the study of ``real'' life as the field of Artificial
Intelligence (AI) stands to the study of ``real'' intelligence. Both of these
``sciences of the artificial'' study the phenomena in their respective domains
by attempting to abstract the {\em logical form} of biological or cognitive
phenomena, and recreating or ``synthesizing'' these abstracted logical forms
within computers or other artificial media. Motivations for pursuing such
studies range from the desire to understand the ``real-thing'' to the goal
of actually producing living and/or intelligent machines.
In fact, the fields of Artificial Life and Artificial Intelligence can
be viewed as two ends of the relatively broad spectrum of the study of how
living entities go about generating their own behaviors in the physical world.
However, whereas AI has picked for study the most complex such entities known
in nature --- human beings --- AL would consider it a major success to
understand how a bacterium works.
Furthermore, the field of Artificial Life takes a distinctly ``bottom-up''
approach to the study of biological phenomena, as apposed to the ``top-down''
approach of traditional Artificial Intelligence. AL has more in common
with the current ``connectionist'' movement within AI than with the more
traditional reasoning, planning, and expert systems approaches.
\section{Contents}
This video tape is divided into three sections: I) History, II) Science,
and III) Clips.
The historical section consists entirely of a remarkable documentary
account of L.S. Penrose --- father of Roger Penrose, the distinguished
Oxford mathematician --- demonstrating a number of ``self-replicating
machines'' constructed out of plywood in the late 1950's and early 1960's.
The science section consists of six separate sequences, illustrating a number
of current research efforts in Artificial Life. The clips section contains a
number of films and video-clips that involved Artificial Life techniques in
their creation or which constitute video-commentaries on Artificial Life.
The individual sequences in these sections are described in more detail
in the pages that follow. All in all, the work presented herein constitutes
a rather varied snapshot of some of the work being done in, or in association
with, the field of Artificial Life. The field itself, and the spectrum of
phenomena to which its methods are being applied, is quite broad and growing
extremely rapidly.

Subject: Alife III Call for Papers
Artificial Life III
June 15-19, 1992
Santa Fe, NM
CALL FOR PAPERS
We are happy to invite contributions for the Third Artificial Life
Workshop, to be held in Santa Fe, New Mexico, June 15-19, 1992.
Artificial Life complements the traditional Biological sciences, concerned
with the analysis of living organisms, by attempting to synthesize behaviors
normally associated with natural living systems within computers and other
"artificial" media. By extending the empirical foundation upon which the
science of Biology rests beyond the carbon-chain based life that has evolved
on Earth, Artificial Life can contribute to Theoretical Biology by locating
"life-as-we-know-it" within the larger context of "life-as-it-could-be."
Contributions may be submitted in the following categories: TALK (please
specify a 20 or a 45 minute talk); POSTER, which may include a computer
display (BYOC); DEMONSTRATION, which includes computer demos and/or videos
(please give time estimate); or OTHER (please specify).
Authors should send an abstract (5 pages at most) to the address below
by January 15, 1992. DO NOT WAIT UNTIL JAN. 14!!! Please try to get your
abstract in early. Authors will be notified of the status of their
contributions by March 15, 1992.
Proceedings of the first two Artificial Life Workshops are now available
from Addison Wesley Publishers (1-800-447-2226 to order). The proceedings
of the second workshop also include a videotape. We intend to emphasize
visualization in the third workshop as well, and encourage contributions
based on working mobile robots.
Contributions to the workshop will automatically be considered for
inclusion in the proceedings. Papers for the proceedings will be due at
the workshop, and papers may be submitted then which were not submitted as
contributions to the workshop itself. The end of the workshop is the
deadline for submission of papers for the proceedings. All papers received
by the end of the workshop will be sent out for review and authors notified
by the end of August.
We will also be holding a greatly expanded "Artificial 4H Show,"
involving exhibits of, judging among, and contests between, various
software and hardware artificial life forms. People who wish to enter
their artificial organisms in the "Artificial 4H Show" should send
a description of what they plan to exhibit to the address below. We
will be announcing a series of contests and challenges for robots,
genetic algorithms, and software life forms soon. Some of these will
carry cash-prizes. All contests and challenges will be carried out
during the workshop.
Abstracts should be sent to:

Subject: Seeking co-sponsors for Alife III
HELP!!!!
We need to raise about $60,000 in corporate sponsorship for the
Third Artificial Life Workshop, to be held in Santa Fe, New Mexico,
June 15-19, 1992.
The previous two workshops have been sponsored almost entirely by
the Santa Fe Institute and the Center for Nonlinear Studies at LANL.
Apple Corp kicked in some $$ for the first workshop as well.
However, the projected costs of the third workshop will exceed the
combined contributions of the SFI and the CNLS by a considerable
amount. In order to keep registration costs down, we must find some
corporate sponsors.
So, how about it out there? Can any of you help out by approaching
your corporations and/or institutions about co-sponsoring the
next Artificial Life workshop? Feel free to call me for details
concerning the workshop and arrangements for becoming a co-sponsor.
Thanks!
