Subject: Workshop on Fluctuations
Fluctuations and Order: The New Synthesis
To be held in Los Alamos, New Mexico on September 9-12, 1993
Organizer: Mark Millonas, T13/CNLS/SFI
Advisory Committee: Alan Bishop, Mac Hyman, Alan Lapedes, Mike Simmons
Sponsors: Center for Nonlinear Studies, the Theoretical Division, Los
Alamos National Laboratory, and the Santa Fe Institute
Manifesto: The workshop will focus on a selection of new paradigmatic
examples of the creative role of fluctuations, where noise plays an
active part in the production of complex phenomena by producing
behavior or order which has no deterministic analog. These new ideas
elevate the importance of fluctuations to a new level, where noise should
now be viewed as a source of order and complex behavior in its own right,
and where dynamics and noise must be understood in a synthetic way. The
goal of the workshop will be to promote an understanding of these new
phenomena and principles among researchers of various fields, and to
stimulate a discussion of how these new paradigms should affect or change
our basic understanding of how complex systems work.
Structure of the workshop: A selection of representative topics has been
chosen. Each topic will be reviewed by a principle researcher in that
field, and then illustrated by talks on applications of that topic to
problems in physics, chemistry, biology, and other fields.
Selected review talks: Noise Induced Transitions (Werner Horsthemke,
SMU), Glassy Dynamics (Austin Angell, Arizona State) , Stochastic
Resonance (Mark Dykman, Stanford), Stochastic Chaos (Linda Reichl, Austin),
Small Noise Asymptotics (R. Maier, Arizona), Mesoscopic Systems (Boris
Altshuler*, MIT), Noise Sustained Structures (R. Deissler, NASA).
Other speakers A. Balatsky (Los Alamos), H. Brand (Bayreuth), D. Chialvo
(Santa Fe), C. Doering (Clarkson), R. Fox(Georgia Tech), R. Kapral
(Toronto), L. Lam (San Jose), R. Landauer (IBM), J. Langer (Santa
Barbara)*, K. Lindenberg (UCSD), S. Lloyd (Los Alamos), A. Longtin

The Topics:
Noise Induced Transitions: Contrary to common belief that randomness is a
nuisance, a disorganizing influence, external noise can create new
dynamical behavior in a large class of nonlinear systems. Often, noise
gives rise to transitions where a spontaneous structuring of the system
occurs, a structuring that is induced by external randomness and that does
not survive without external fluctuations. These noise-induced transitions
reflect a symbiotic relation of order and fluctuations and force us to
reappraise the role of randomness in complex systems.
Stochastic Resonance: The addition of noise to certain types of driven
systems can paradoxically cause an increase in the signal to noise ratio.
In this case the addition of noise actually causes a signal to become
clearer. Stochastic resonance has been suggested as an explanation of
periodic ice ages, and as an effective biological mechanism for the
amplification of signals in a noisy environment.
Glassy Dynamics: Glassy and other disordered systems have long been known
to display unconventional types of relaxation and transport; the two most
prominent are perhaps non-Arrhenius temperature dependence of a number of
transport properties and non-exponential time dependence of relaxation
after a perturbation. The experimental phenomena and some recent
theoretical attempts to explain them will be reviewed.
Low Noise Asymptotics and Stochastic Chaos: It can be shown that in the
low noise limit a description of stochastic processes in terms of
trajectories which obey a set of Euler-Lagrange equations is possible.
This behaviors is completely unlike the behavior of the deterministic
system, and is capable of complex behavior, such as a transition to chaos,
even when the deterministic system is extremely simple. Stochastic chaos
can be viewed as a generalization of quantum chaos, since all the results
of quantum chaos can be applied to the subset of stochastic systems which
obey detailed balance. However a whole new set of phenomena going beyond
detailed balance exist. One of these is the onset of "focusing" or
stochastic caustics. The analysis of the dynamics of these special
trajectories provides a completely new set of paradigms and tools taken
from nonlinear dynamics to be applied in an attempt to understand the
properties nonlinear noise-driven systems.
Mesoscopic Effects: Mesoscopic systems are ones in which there are at
least two important scales involved. The systems are large in comparison
with some scale, such as the quantum scale, but small on the macroscopic
scale. In such system there is often a highly nontrivial interplay between
dynamics and fluctuations.
Noise-Sustained Structures: In convectively unstable systems external
noise is selectively and spatially amplified giving rise to a
noise-sustained structure. In such a system a coherent spatiotemporal
pattern can emerge from and be sustained by random noise. Since any
spatially extended system with nonzero group velocity is convectively
unstable at the onset of the instability, noise-sustained structures are
expected to be very common in nature.

2nd European Conference on Artificial Life
SELF-ORGANIZATION AND LIFE, FROM SIMPLE RULES TO GLOBAL COMPLEXITY
Brussels, May 24-26th, 1993
Natural and artificial systems governed by simple rules exhibit self-
organisation leading to autonomy, self-adaptation and evolution. While these
phenomena interest an increasing number of scientists, much remains to be done
to encourage the cross-fertilisation of ideas and techniques. The aim of this
conference is to bring together scientists from different fields in the search
for common rules and algorithms underlying different systems. The following
themes have been selected :
- Origin of life and molecular evolution
- Patterns and rhythms in chemical and biochemical systems and interacting
cells
(neural network, immune system, morphogenesis).
- Sensory and motor activities in animals and robots.
- Collective intelligence in natural and artificial groups
- Ecological communities and evolution .
- Ecological computation.
- Epistemology
We are also planning demonstrations of computer programmes, robots and
physico-chemical reactions, both in vivo and in video.

Subject: Re: L Systems Info Needed
Hi, people:
This is JJ Merelo, from Granada, Spain. I have endeavoring to create
what you could call a virtual forest, with realistic-looking plants in 3D.
I have already met references by Prusinkiewicz and Oppenheimer (in
Alife #1), and found some software for Sun in the alife ftp site called
lsys. I have been scanning old issues of IEEE Computer Graphics & Apps, for
references on the subject of 3d design of realistic-looking plants.
Are there any more references on the subjects? Is anybody working
on a similar subject?
Thanks a lot...I'll compile all references and/or people working
on the topic and post them.

Subject: BEAM Robot Olympics Results: Sorry, it's gonna be a while...
Newsgroups: comp.robotics
Hi all.
For those that don't know already, the 2nd International BEAM Robot
Olympic Games finished April 22-25th weekend to some satisfying results.
160 roboticists and as many machines displayed before record public crowds
at the Ontario Science Centre in Toronto, Canada. Amazingly enough,
competitions and lectures actually happened on time and mostly as scheduled,
prizes went out and we only lost one organizer due to electrocution.
Overall the show was delightfully surprising, one of the main features
being that few (if any) of the robots resembled each other at all. Everywhere
there was something wierd and interesting. Although many displayed
semi-functional designs, the real attractions were the people who worked
feverishly getting their devices running in time for events. Massive
good-natured cheating, development and advice-swapping occurred amongst
the participants, and the crowd looked on with facination at mini
machine shops, dexterous robot sea urchins, flying dolly-parton machines,
singing trash cans, piddling globes, mechanical vegetables, solar roller
coasters, 4-bar walkers, lego dogs, twitching robot ecologies, and self
mobile floor polishers.
Like I said, interesting.
Well, following the show, it turns out there's just a tonne of work
to compile it all. It's going to be a few weeks I think. During that
time we'll be compiling videos, making the new rule sets available by FTP,
and sorting out the details for next time. The next show is tentatively
scheduled for March Break, 1994, at the OSC again, although if people
hold true to their promise of entering, we might have to rent out the
Skydome instead.
I'd like to give a warm thanks to all the sponsors for the show; the UofW
IEEE Student Chapter, ITRC Ont., The OSC, BCS Electronics, Mondotronics CA,
and the Un. of Waterloo Math and Computer Science Department.
And special thanks to all those University students and friends who showed
grace under pressure, sacrificed their weekend, and even missed Star
Trek to help out. Good doggies. Have a biscuit. :)
Also thanks to the international range of competitors who came with their
mechanized miracles and enthusiasm. It was great to meet you and share
ideas, however briefly. May your soldering irons never grow cold.
Advice on next years competition is welcome. We already know about the
name tags, but as 60% of our competitors didn't register until the
second day of the show it was kind of hard. It'll never be essential,
but next time, file your entrance forms early, willya? One faux pas I
will admit to is not organizing any nightlife activity. I'd just assumed
netters would just congregate somewhere by word of mouth, but I guess things
were just too hectic for that. Next time, definitely.
Is all.

Subject: Conference: Parallel Problem Solving from Nature III
The third international conference on
Parallel Problem Solving from Nature
(PPSN III)
First Announcement
and
Call for Papers
The third international conference on Parallel Problem Solving from Nature
(PPSN III) will be held in Jerusalem, Israel between 9-14th October, 1994.
This meeting will bring together an international community from academia,
government and industry interested in algorithms suggested by the unifying
theme of natural computation.
Natural computation is a common name for the design, theoretical and
empirical understanding of algorithms gleaned from nature. Characteristic
for natural computation is the metaphorical use of concepts, principles and
mechanisms underlying natural systems. Examples are genetic algorithms,
evolutionary programming and evolution strategies inspired by the
evolutionary processes of mutation, recombination, and natural selection
in biology, simulated annealing inspired by many--particle systems
in physics, and algorithms inspired by multi--cellular systems like neural
and immune networks.
Topics of particular interest include, but are not limited to:
evolution strategies, evolutionary programming,
genetic algorithms and classifier systems,
other forms of evolutionary computation,
simulated annealing, neural and immune networks,
machine learning and optimization using these methods,
their relations to other learning paradigms,
and mathematical description of their behaviour.
An emphasized theme of the conference will be the successful application
of these techniques to solve real problems in manufacturing, design,
planning and engineering.
The conference will be held in a kibbutz 10 min. from the old city of Jerusalem
on top of the Judea mountain ridge overlooking Bet-Lehem and Jerusalem.
The conference programme will include visits to historical, religious and
contemporary monuments in Israel.
Important Dates:
1 February 1994: Submissions due
30 April 1994: Notification to authors
1 June 1994: Revised, final camera-ready papers due
9--14 October 1994: Conference dates
