ATR is located in the new Kansai Science City, near Nara and Kyoto. Tom Ray came to ATR as an invited researcher on August 8, 1993, and is on a two year leave of absence from the University of Delaware. Current email is ray@hip.atr.co.jp, ray@udel.edu is forwarded. Kurt Thearling joined ATR as a research affiliate on November 1, 1993. Kurt remains an employee of Thinking Machines, but will be working on the Tierra project at ATR until April 1994. Email is kurt@hip.atr.co.jp, kurt@think.com is forwarded. The primary objective of the Tierra project for the coming months will be to experiment with the evolution of multi-cellular digital organisms, which are parallel processes. Several other evolutionary projects are also underway in the Evolutionary Systems Department at ATR as follows: - CAM-Brain project aiming at growing/evolving an artificial brain, which contain thousands of interconnected artificial neural network modules, inside special hardware called Cellular Automata Machines. Hugo de Garis, degaris@hip.atr.co.jp - Emergent Intelligence project modeling intelligence as a non-linear developmental process from genotype to phenotype, under the influence of the environment. Jari Vaario, jari@hip.atr.co.jp - EgoWare (Evolutionary Generator of Genome in Hardware) project aiming at self-producing hardware-description programs by evolving HDL (Hardware Description Language) production rules and derivation trees. Hitoshi Hemmi, hemmi@hip.atr.co.jp and Junichi Mizoguchi, mizo@hip.atr.co.jp - Learning methods for modularized neural networks with evolvability aiming at developing an autonomous system consisting of heterogeneous neural network modules.

The most important two manuscripts have also been placed in the Tierra ftp site (see section 8 below). These two manuscripts are in the /doc directory of the ftp site. The one in press at the journal Artificial Life is available as the file Zen.tex. The one submitted to Physica D is available as the file PhysicaD.tex. Unfortunately this second manuscript includes a lot of figures which are not available electronically. Title and abstract of Zen.tex: Ray, T. S. In press. An evolutionary approach to synthetic biology: Zen and the art of creating life. Artificial Life 1(1): xx--xx. MIT Press. Our concepts of biology, evolution and complexity are constrained by having observed only a single instance of life, life on Earth. A truly comparative biology is needed to extend these concepts. Because we can not observe life on other planets, we are left with the alternative of creating artificial life forms on Earth. I will discuss the approach of inoculating evolution by natural selection into the medium of the digital computer. This is not a physical/chemical medium, it is a logical/informational medium. Thus these new instances of evolution are not subject to the same physical laws as organic evolution (e.g., the laws of thermodynamics), and therefore exist in what amounts to another universe, governed by the ``physical laws'' of the logic of the computer. This exercise gives us a broader perspective on what evolution is and what it does. An evolutionary approach to synthetic biology consists of inoculating the process of evolution by natural selection into an artificial medium. Evolution is then allowed to find the natural forms of living organisms in the artificial medium. These are not models of life, but independent instances of life. This essay is intended to communicate a way of thinking about synthetic biology that leads to a particular approach: to understand and respect the natural form of the artificial medium, to facilitate the process of evolution in generating forms that are adapted to the medium, and to let evolution find forms and processes that naturally exploit the possibilities inherent in the medium. Examples are cited of synthetic biology embedded in the computational medium, where in addition to being an exercise in experimental comparative evolutionary biology, it is also a possible means of harnessing the evolutionary process for the production of complex computer software. Title and abstract of PhysicaD.tex: Ray, T. S. Submitted. Evolution, Complexity, Entropy, and Artificial Reality. Physica D. The process of Darwinian evolution by natural selection was inoculated into four artificial worlds (virtual computers). These systems were used for a comparative study of the rates, degrees and patterns of evolutionary optimizations, showing that many features of the evolutionary process are sensitive to the structure of the underlying genetic language. Some specific examples of the evolution of increasingly complex structures are described. In addition a measure of entropy (diversity) of the evolving ecological community over time was used to study the relationship between evolution and entropy. 3) Upcoming Tierra lectures Section deleted to save space... 4) Change of address for Virtual Life Section deleted to save space... 5) Tierra video animation The Santa Fe Institute has produced a thirteen minute promotional video, which includes a roughly five minute segment discussing the Tierra research project.

Tom Ray ------------------------------ From: jhorn@gal1.ge.uiuc.edu (Jeff Horn) Subject: IlliGAL announcement IlliGAL FTP SERVER and NEW PUBLICATIONS: The Illinois Genetic Algorithms Laboratory (IlliGAL) is pleased to announce the implementation of our new ftp server and the publication of several new papers and technical reports. (1) NEW PUBLICATIONS: The Illinois Genetic Algorithms Laboratory (IlliGAL) is pleased to announce the following reports and publications. Most IlliGAL technical reports, as well as reprints of the other publications, are available in hardcopy and can be ordered from the IlliGAL librarian, Eric Thompson (see below for ordering information). Those papers marked with an asterisk (*) are also available electronically on our new ftp server (see below for ftp instructions). New IlliGAL: IlliGAL Report No 93005* Title: Multiobjective Optimization Using the Niched Pareto Genetic Algorithm Authors: Jeffrey Horn and Nicholas Nafpliotis (NOTE: This final version is significantly enhanced over the draft version that was distributed at ICGA 5 this summer, +10 pages!) ABSTRACT Many, if not most, optimization problems have multiple objectives. Historically, multiple objectives (i.e., attributes or criteria) have been combined ad hoc to form a scalar objective function, usually through a linear combination (weighted sum) of the multiple attributes, or by turning objectives into constraints. The most recent development in the field of decision analysis has yielded a rigorous technique for combining attributes multiplicatively (thereby incorporating nonlinearity), and for handling uncertainty in the attribute values. But MultiAttribute Utility Analysis (MAUA) provides only a mapping from a vector-valued objective function to a scalar-valued function, and does not address the difficulty of searching large problem spaces. Genetic algorithms (GAs), on the other hand, are well suited to searching intractably large, poorly understood problem spaces, but have mostly been used to optimize a single objective. The direct combination of MAUA and GAs is a logical next step for multiobjective GA optimization. However, there is an alternative approach. It turns out that the GA is readily modified to deal with multiple objectives by incorporating the concept of Pareto domination in its selection operator, and applying a niching pressure to spread its population out along the Pareto optimal tradeoff surface. In this report, we discuss the general issues involved in searching large problem spaces while trying to optimize several objectives simultaneously. We explore various combinations of decision analysis techniques, specifically MAUA, and GAs. Finally, we introduce the Niched Pareto GA as an algorithm for finding the Pareto optimal set. We compare and contrast the Niched Pareto GA with MAUA. And we demonstrate the ability of the Niched Pareto GA to find and maintain a diverse ``Pareto optimal population'' on two artificial problems, and an open problem in hydrosystems.

This is particularly evident when one observes the intense pace of collaborations, mergers, and corporate purchases at the boundary between entertainment and computing. The popular press has referred to this as "the merger of Hollywood and Silicon Valley". For this merger to succeed in the long term, machines must become competent in entertainment industry tasks presently performed by humans. This is very much the domain of AI research and development. Thus, this workshop focuses on the applications of artificial intelligence and related technologies to entertainment. The purpose of the workshop is that by broadly soliciting papers in the area, which has not been studied by much of the AI community in the past, we expect to draw an overall picture of AI opportunities in the entertainment industry. Also, we expect that information will be exchanged to influence AI research directions and to facilitate active research on AI for entertainment. In 1990 and 1992, AAAI sponsored successful workshops in the comparatively narrow areas of interactive fiction and interactive entertainment. For this workshop, we welcome papers which clearly demonstrate use (including both actual use and ideas & proposals) of AI and related technologies (such as artificial life, neural networks, robotics, and genetic algorithms) in all areas of entertainment, including: - Film (Movie, Video, etc) production - Computer graphics and animation - Interactive fiction, simulated worlds, role playing games - Video games - Network-based games - Virtual reality - Autonomous systems and agents - Interactive media - Music, sound, and speech - Drama and story-telling - Robotics, animatronics - Theme park applications The 1994 AAAI conference will include an AI-based Arts Exhibition, technical paper presentations in the area of Arts and Entertainment, and other activities relevant to the topics of this workshop. We expect the conference to attract a variety of people working in the area, and intend the workshop to provide an opportunity for many of them to meet and discuss plans for further research and development. Submissions: Send two copies of an extended abstract, no longer than 8 pages, to both workshop co-chairs. The deadline for submission is March 18, 1994. Notification of acceptance will be mailed on April 8.

Dear EC'ers, I'd like to introduce the newly opened SAnta Fe Institute's Evolutionary computation Repository. It "lives" on SFI's FTP server ftp.santafe.edu, under the "/pub/EC" hierarchy. Pointers to the complete contents of SAFIER, i.e., a concatenation of all its README files is kept in "sfi.santafe.edu:/pub/EC/CONTENTS", and thus should be your first choice to "take-away" from this archive, on your initial visit. A more elaborate handbook, that moreover lists the current CONTENTS in its appendix, entitled "The Navigator's Guide to SAFIER" is available for A4 paper, and US letter size paper as "sfi.santafe.edu:/pub/EC/handbook/safier.ps.gz", and "sfi.santafe.edu:/pub/EC/handbook/safier-US.ps.gz", repectively. Those of you using the World Wide Web information service, can browse SAFIER with an URL pointing to "ftp://sfi.santafe.edu/pub/EC" The following footer, appears at the end of all README files, so please don't get confused while browsing the CONTENTS file: -==-==-==-==-==-==-==-==-==-==-==-==-==-==-==-==-==-==-==-==-==-==-==-==-==- Please refer to the toplevel README file sfi.santafe.edu:/pub/EC/README for further explanations. Thanks. -joke -==-==-==-==-==-==-==-==-==-==-==-==-==-==-==-==-==-==-==-==-==-==-==-==-==- So, here's the top level README file that will explain the rest: --- $Id: sfi.santafe.edu:/pub/EC/README,v 1.1 1993/11/28 16:12:41 joke Exp $ Welcome to _/_/_/ _/ _/_/_/_/ _/_/_/ _/_/_/_/ _/_/_/ _/ _/ _/_/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/_/_/ _/ _/ _/_/_/ _/ _/_/_/ _/_/_/ _/ _/_/_/_/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/ _/_/_/ _/ _/ _/ _/_/_/ _/_/_/_/ _/ _/ The SAnta Fe Institute's Evolutionary computation Repository. -=*=- INTRODUCTION This directory hierarchy, titled SAFIER, contains a documented collection, i.e., compilation of electronically available resources related to the field of Evolutionary Computation (EC). It is divided into several categories that reflect the current main research paradigms: Genetic Algortihms (GA), Evolution Strategies (ES), Evolutionary Programming (EP), Genetic Programming (GP), and Classifier Systems (CFS). All these specialized sub-hierarchies are completed with a general Evolutionary Algorithm (EA) folder for hybrid or other approaches not contained in the previous list. Electronically available resources in this context means compressed PostScript (cf CONVENTIONS) versions of research papers, and journal articles; publicly available software packages, and test data sets. Moreover, SAFIER provides a place for the FAQ (list of Frequently Asked Questions and their respective answers) of the USENET newsgroup comp.ai.genetic, for easy access between postings, i.e., the 3 ASCII parts, and the PostScript version. -=*=- CONVENTIONS All folders in the SAFIER hierarchy contain a file, named README, which holds information on all the other files in that particular folder. The addressing scheme for any file in SAFIER is simply the complete path to that file, with the FTP server's symbolic address prepended. E.g. the README that lists all papers in the genetic algorithm section should be refered to as "sfi.santafe.edu:/pub/EC/GA/papers/README" For a general overview refer to "sfi.santafe.edu:/pub/EC/OVERVIEW". The complete contents of SAFIER, i.e. a concatenation of all README files, is available in "sfi.santafe.edu:/pub/EC/CONTENTS" All PostScript and ".tar" files, have been compressed to reduce disk space using the GNU compression utility "gzip". You thus have to use "gunzip" to decompress the files after downloading. For further explanations consult "The Navigator's Handbook to SAFIER" that's available as "sfi.santafe.edu:/pub/EC/handbook/safier.ps.gz" for A4 paper, and "sfi.santafe.edu:/pub/EC/handbook/safier-US.ps.gz" contains an US letter size version. -=*=- CONTRIBUTIONS Your contributions are always welcome. Send papers, software, etc. via e-mail to the current SAFIER maintainer, preferably including a short (3-4 lines) description, that can just be "dropped" into the appropriate README file. -=*=- INQUIRIES Inquiries addressing general SFI specific issues, e.g. BBS related infos, should be directed to Scott Yelich .

Davidor (Israel) B. Manderick (The Netherlands) K. De Jong (USA) H. Muhlenbein (Germany) H. Kitano (Japan) H.-P. Schwefel (Germany) R. Maenner (Germany) The International Conference on Evolutionary Computation - The Third Parallel Problem Solving from Nature (PPSN III) will be held in Jerusalem, Israel between 9-14 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. The conference programme committee will particularly welcome application papers dealing with these techniques to solve real problems in manufacturing, design, planning and engineering providing these are of the highest level. The application type of papers should either exhibit outstanding performance in solving particular problems in contrast to other techniques or address real problems of significant and unique importance to science. 5 hard copies of original work in the related topics typed in 12pt single column and maximal length of 10 pages including all figures and references should be sent to H.-P. Schwefel, programme co-chair by March 1, 1994. One copy should contain the names of the authors, affiliation, and full addresses. The remaining 4 copies should be anonymous and contain only the title and body of paper including figures and references. This procedure is adopted to enhance anonymous peer review. The conference will be held in a kibbutz 10 minutes from the Old City of Jerusalem on top of the Judean mountain range overlooking Bethlehem and Jerusalem. The conference programme will include visits to historical, religious and contemporary monuments in Israel. IMPORTANT DATES: March 1, 1994 - Submission of full paper May 30, 1994 - Notification to authors July 1, 1994 - Submission of revised, final camera ready papers GENERAL INFORMATION Venue The conference will be held at the Mitzpeh Rachel Kibbutz Congress Center on the southern outskirts of Jerusalem, overlooking Bethlehem. A swimming pool and tennis courts are on the premises and there is easy access by public transportation to the center of Jerusalem. Jerusalem is an excellent location for an international convention. Just 40 minutes from the Ben Gurion International Airport, Jerusalem offers a variety of cultural and religious experiences that link its historic past to its dynamic present. History will come alive as you discover the shrines of the world's great religions, stroll around the walls of the Old City, visit the reconstructed city's main streets, and enjoy the extensive collections in Jerusalem's numerous museums that house amongst its treasures, the Dead Sea Scrolls, the Billy Rose sculpture garden, archaeological finds, calligraphy and other works of art. As the birthplace of Judaism and Christianity, and as one of Islam's holy cities, Jerusalem is a captivating, uniquely significant city to millions of people throughout the world. The conference will offer participants an opportunity to combine a scientific gathering with the natural beauty of a country that enjoys a pleasant Mediterranean climate and a unique city, Jerusalem. Language The official language of the conference is English. All lectures, posters and printed material will be in English. Climate The weather in October in Jerusalem is sunny and mild during the day. The temperature is cooler in the evenings. Some rain may be expected, but not very likely.
