Subject: re: internet virus (no)
According to the Internet CERT (Computer Emergency Response Team),
there's no virus or worm or other spreading-program known to be
active on the net; just some system-cracker more-or-less manually
exploiting known security holes. DC

Subject: what is life & what will foster the evolution of inorganic forms?
One of the problems with allowing to develop (not building)
AL forms in environments outside of computer memory is the translation
difficulty of _organizing_code_ into physical entity. Organic life forms are
little chemical factories drawing relatively low-level resources from their
immediate environment. This would be difficult to generate in physical AL.
Perhaps a compartmentalized solution would help: a compartment where
organizing code can produce objects capable of building; a compartment where
these objects interact in a highly (altho not entirely) predictable environment
to assemble a living (no quotes) entity; and a compartment where the maturing
entity interacts with other life forms and has the majority of its fitness
tested.
Question: if a computer were a good initial place to hold the
underlying code, where during development should the leap into the physical
world be made, and how? Could it be = computer, "factory", street? Then,
when is it AL and when is it a Buick?
I have yet to see a definition of life of any sort that satisfied me.
The one expounded in Sesame Street is at least cute. The usual definitions
in biology texts (the study of life!) are undoubtedly wrong. IWSSLS-1 did
more to dramatize the question than answer it. Is there any move afoot to
develop an effective definition, given the image breaking challenge of
the alifers?

FIRST ANNOUNCEMENT
and
CALL FOR PAPERS
International Workshop
Parallel Problem Solving from Nature
(PPSN)
October 1 - 3, 1990
University of Dortmund, Germany F.R.
Scope
With the appearance of massively parallel computers increased
attention has been paid to algorithms which rely upon analogies to
natural processes. The workshop scope includes but is not limited
to the following topics:
- Darwinian methods such as Evolution Strategies
and Genetic Algorithms
- Boltzmann methods such as Simulated Annealing
- Classifier systems and Neural Networks insofar as
problem solving predominates
- Transfer of other natural metaphors
to artificial problem solving
The objectives of this workshop are
- to bring together scientists and practitioners working on
and with such strategies.
- to gather theoretical results about as well as experimental
comparisons between these algorithms.
- to discuss various implementations on different parallel
computer architectures (e.g. SIMD, MIMD, LAN).
- to look for current and future applications in science,
technology, and administration.
- to summarize the state of the art in this field which up to
now has been scattered so widely among disciplines as well
as geographically.
Submission of papers, Proceedings
Prospective authors are invited to submit 4 copies of an extended
abstract of two pages to the conference chair before June 1, 1990.
All contributions will be reviewed by the programme committee and
up to about 30 papers will be selected for presentation. Authors
will get notice about acceptance or rejection of their papers by
July 15, 1990.
Full papers will be due on September 1, 1990. They will be delivered
to all participants at the conference as a prepublication volume.
Final papers for the proceedings of the workshop should be finished
immediately after the workshop. Details about the format of the
camera-ready final papers will be distributed later.
Language
The official language for papers and presentations is English.
