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.

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. ------------------------------ Date: Sat, 1 May 93 20:43:22 PDT From: fayyad@aig.Jpl.Nasa.Gov (Usama Fayyad) Subject: Job opportunities for Ph.D.'s at JPL Employment Opportunity for Ph.D. Candidates: The Artificial Intelligence (AI) Group at the Jet Propulsion Laboratory (JPL), California Institute of Technology is seeking candidates at the Ph.D. level to join the Machine Learning Research and Applications subgroup.

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. ------------------------------ From: Hans-Paul Schwefel Date: Fri, 7 May 93 15:52:20 +0200 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 PPSN-94 Conference committee: Conference Chair: Y.
