Subject: Primordial Soup Program

			ANNOUNCING PRIMORDIAL SOUP

I have recently completed Primordial Soup, an a-life program that
spontaneously generates self-reproducing organisms from a "sterile
soup", i. e. a memory space filled with pseudo-random numbers.

The program is similar in concept to Thomas Ray's Tierra software.  I
used a number of his ideas in the design of Primordial Soup.

The code runs under UNIX.  It has been tested on both SunOS
and System V platforms.  I have uploaded the code to ftp.cognet.ucla.edu.
It is in the file /alife/public/psoup1.0.tar.Z.

If you do not have Internet FTP access, e-mail me and I will send
you a shar file by return e-mail.

The excerpt below is from the README file.

-Marc de Groot
marc@kg6kf.ampr.org

---Begin excerpt
        Primordial Soup is an artificial life program.  Organisms in the
form of computer software loops live in a shared memory space (the "soup")
and self-reproduce.  The organisms mutate and evolve, behaving in
accordance with the principles of Darwinian evolution.
        The program may be started with one or more organisms seeding the
soup.  Alternatively, the system may be started "sterile", with no
organisms present.  Spontaneous generation of self-reproducing organisms
has been observed after runs as short as 15 minutes.
        Each organism is a software loop which block-copies itself to another
place in the soup and starts a new organism, or process, executing
at the start of the copied block.
        The loops are written in a pseudo-assembly language.  The
assembly language is executed by a multitasking interpreter.  One instruction
is executed from each organism in turn, so that the organisms effectively
run simultaneously.
        The organisms are in a completely shared memory space, and so
multiple organisms may have their program counters pointing at the
same block of code, executing the same program.  Organisms may also
overwrite one another freely.  This allows for a limited form of sexual
reproduction: the organisms share genes by the mechanism of one partially
overwriting another.
        Another source of mutation besides sexual reproduction is provided.
It is a simulation of background radiation.  Every so many instructions
one bit in the soup is complemented at random.  The rate at which the
bit-flips occur is controllable by the user.

Subject: A review of ``The Embodied Mind: Cognitive Science and Human Experience''

``The Embodied Mind: Cognitive Science and Human Experience''
{\em Francisco J. Varela, Evan Thompson and Eleanor Rosch}
The MIT Press, Cambridge, MA, 1991. xx + 308  pp.  $25.00.
ISBN 0-262-22042-3. 

``The Embodied Mind'' starts with the examination of a fundamental
circularity in the relationship between cognitive science and human 
experience. The authors take the position that any scientific 
description of behavior is itself a product of the structure of our 
collective cognitive apparatus. Too often, they claim, when an abstract,
theoretical attitude is taken towards the study of the mind, this 
fundamental circularity gets ignored leading to a belief that our 
self-understanding which is based on experience is false and will 
someday be replaced by a calculus of behavior. The tension between the 
abstract attitude and experience is heightened in a field where the mind 
itself is the focus of investigation, namely, cognitive science.

The authors review the current state of cognitive science.
They classify all of cognitive science into three categories;
{\em cognitivist\/}, {\em emergent\/} and {\em enactive\/}. 
Cognitivism is described as ``no computation without representation.''
The world is pregiven with fixed objects and properties. The self
in turn carries around an internal representation which is used in 
perception and in action. The emergent school is based on the paradigm 
of {\em self-organization\/}. Here, the self is constantly adapting and 
changing its internal representation in the face of a non-stationary 
environment. The authors claim that both the emergent and cognitivist 
schools are operating on tacit beliefs about the self and the world. 
They argue that the basic idea of a world with a fixed set of properties 
and a self which has an internal representation of these properties is 
common to both schools. The authors plight their troth with the enactive 
school which dispenses with the assumptions of a world with fixed 
properties and with a self which is a constant reference point for 
representation. The main point stressed here is that there is no ground 
to be found in the world or in the self.  Unlike arguments by Searle and 
Dreyfus which are strongly humanistic, the authors do not retreat into a 
solipsistic viewpoint from which cognitive science is criticized. 
Instead, mutually structured coupling between organism and environment 
now holds the key to understanding perception and action. 
All foundationist theories of mind and nature are strongly criticized
including the belief that there are no foundations, namely, nihilism.
The authors refer to the craving for  ultimate realist foundations of 
self and world as ``the Cartesian anxiety'' since without foundations, 
we would drown in a morass of skepticism, nihilism, insanity, 
depression, darkness and chaos. The alternative offered is enaction as 
embodied cognition. Meaning spontaneously emerges via a history of 
structured coupling between an organism and an environment. The authors
cite Rod Brooks as paradigmatic of enactive cognitive science. 

After describing enactive cognitive science as meeting human experience
half way, the authors then take up the task of the investigation of 
human experience itself. Buddhist mindfulness/awareness meditation 
is offered as a way of experiencing the  examination of  experience.
The authors point out that a key insight arising from the practice of
meditation is the extent to which our minds are occupied in unmindful,
and disembodied reflection on experience. They equate this abstract 
activity with the general abstract attitude which is so pervasive in 
approaches to cognitive science. The method of mindfulness/awareness 
is described in detail along with several pointers to the Buddhist 
tradition and doctrine of no self. 

An example of the mindfulness/awareness approach to the examination of 
experience can be seen by a three-way review of the book: 
cognitivist, emergent and enactive.
In what is to follow, the three positions have been caricatured.
The cognitivist review is disembodied. The book is treated as an object
in the ``real'' world with  fixed ideas and properties which can be 
objectively described. The simplistic three-way distinction of 
approaches to cognitive science follow from this standpoint.
The emergent review is describing the book as a deep object which has 
resulted from a historical process. Likewise, the reviewer (also the 
result of a long process) is reviewing the book with unavoidable bias. 
The enactive review is not a review of the book but a view of the book 
in the process of embodied reflection. 

Cognitivist:

``The Embodied Mind'' starts with the examination of a fundamental
circularity in the relationship between cognitive science and human 
experience. The authors take the position that any scientific 
description of behavior is itself a 
product of the structure of our collective cognitive apparatus.........

Emergent:

This book is an important collaboration between veterans Francisco 
Varela and Eleanor Rosch and newcomer Evan Thompson. For about two and
a half decades now, Varela has been arguing for a mature phenomenology.
This book is a passionate and richly detailed argument warning us
that the fate of human experience might be in the hands of people who 
ignore the fundamental circularity between cognitive science and human
experience. While it is not easy for me to see the progression of Eleanor
Rosch (not having read her Buddhist papers), it's clear that Varela has 
achieved a personal synthesis of phenomenology, cognitive science and 
Buddhism.......

Enactive:

.......Varela, Thompson and Rosch seem to be intent on smashing the myth
of representation. ``I'' like it but it's too aggressive.
Maybe Varela is tired of not getting his message
across. After all, ``we'' are trying to find a formalism for perception
and action into which ``we'' can bury ourselves. Looking for a formalism 
is half the fun. The enactive approach seems to be not amenable to a 
formalism but that might be because the examples like Brooks are 
quasi-formalism free. Takes potshots at the transcendental self like 
atman, the soul etc. Very radical and ``I'' like it but makes ``me'' 
uneasy. Formalisms are not closed, cognitivism yields quite
gracefully to emergent. Emergent to enactive becomes difficult if 
prior sense of independent self and world are taken as absolute. 
Instead, why not focus on self-organization which is common to enactive 
and emergent? Wonder if these guys realize how radical they are. After 
all, with no self {\em and world\/}, shouldn't their
enactive cognitive science actually be enactive science with a closed 
loop between physics and perception.......

Notice that the enactive review is a view of the thoughts of the reviewer
in the process of reviewing the book. I decided to review the book and
then sat down and wrote down the thoughts as they occurred. 
Consequently, the enactive review does not break the review down into
first person or third person. Hence, it is possible to extract an
objectivist or subjectivist review from the enactive review but 
not vice-versa.

Subject: Tierra Update: V3.11 release

                                TIERRA UPDATE:
   (Version 3.11 now available, FTP site reorganized, New Tools, Bug Fixes,
      Genebank Verification, Garbage Collection, New Genomes, Mneumonics
                Shortened, Virtual Extraction, DEC Grant, Sex)

This message contains:

1) Availability of Tierra V3.11 source code
   a) by ftp
   b) by snail mail on disk
2) FTP Site Reorganized
2) New Tools
3) Bug Fixes
4) Genebank Verification
5) Garbage Collection
6) New genomes distributed
7) Opcode mneumonics limited to six characters
8) Virtual Extraction
9) Grant from Digital Equipment Corporation
10) Future Sex

1) Availability of Tierra V3.11 source code

   a) by ftp

     The V3.11 source code, the source code, and DOS executables of all tools
is available now.  If you use the software, be sure to pick up new versions
soon from the ftp site.  The source in the ftp site will be replace on a
roughly monthly or bi-monthly basis.

     The complete source code and DOS executables are available by anonymous
ftp at:

tierra.slhs.udel.edu [128.175.41.34] and
  life.slhs.udel.edu [128.175.41.33]

in the directories: DOS/, almond/, beagle/, doc/, and tierra/.

To get it, ftp to tierra or life, log in as user "anonymous" and give your
email address (eg. tom@udel.edu) as a password.  Be sure to transfer binaries
in binary mode (it is safe to transfer everything in binary mode).
Each directory contains a compressed tar file (filename.tar.Z) and a SRC
directory that contains all the files in raw ascii format.  You can just
pick up the .tar.Z files, and they will expand into the complete directory
strucutre with the following commands:

uncompress tierra.tar.Z
tar oxvf tierra.tar

   b) by snail mail on disk

     If you do not have ftp access you may obtain everything on DOS disks
by making a check for $65 (US dollars drawn on a US bank) payable to
Virtual Life.  Specify 3.5" or 5.25" disks.  Send the check to one of the
following addresses:

Tom Ray                  (January through August)
Santa Fe Institute
1660 Old Pecos Trail
Suite A
Santa Fe, NM 87501

Virtual Life             (September through December)
P.O. Box 625
Newark, Delaware 19715

     The DOS disks contain everything but ALmond.  They include DOS
executables, source code and documentation.  The DOS disks include an easy
installation program.  This is the same source and executables available in
the ftp site.  If you have ftp access, there is no need to buy the disks.

2) New Tools

     Several new (and some old) tools, developed by Dan Pirone and Tom Ray,
are now fully documented and available in the ftp site:

rnd_inst - A tool for altering the physics of the system by randomly mapping
     opcodes to instructions, with some optional restrictions on hamming
     distances between pairs of instructions.  The output is an opcode.map
     file.

probe - A tool for surveying the genebank, with various optional selection
     criteria (a new tool, but proving very useful).

tieout - A tool for generating x,y data from the tierra.log file.  This is
     used on a regular basis to generate graphics of size of creatures over
     time during a run.

diverse - A tool that reads the birth and death records (break.X files) output
     by Tierra and transforms them into various measures of diversity, for
     graphical or other analysis.

beagle - A DOS only tool which provides a variety of graphical displays of
     the output from the Tierra simulator.  It is used after a run, and is
     highly recommended as a tool for analyzing the results of a run.

run_info - A function of the beagle program, also available as a stand-alone,
     due to its hunger for memory.

fragment - A function of the beagle program, also available as a stand-alone,
     due to its hunger for memory.

ALmond - A UNIX only tool which runs as a separate process on the same or a
     different machine.  ALmond establishes socket communications with a
     running Tierra, and provides a color display of the spatial distribution
     of the creatures in the soup, showing all births and deaths.  This tool
     has some new functions: you can view the positions of the instruction
     pointers, or the activity of the moviab instruction.

3) Bug Fixes

histograms - Version 3.1 included some obvious errors in the histogram
     display.  These have been corrected.

moviab - This instruction allows creatures to alter their own genome by
     writing on themselves.  Before V3.11, the genebanker did not watch
     for genetic changes occurring in this manner.  This created observational
     errors comparable to the ploidy bug corrected in V3.1.  The genebanker
     now catalogs genetic change by this mechanism.  It is believed that
     the genebanker is now fully reliable (see below).

chmod - The chmod function was supposed to return a value, but did not.
     This had the consequence that a flag was set every time a creature
     allocated space for a daughter, and these were recorded with the
     demography data associated with each creature.  This has been corrected.

arg r option - The arg r option (replace or add) was not working, but
     is now.

4) Genebank Verification

     Error checking code has been added which completely verifies that the
distribution of genotypes in the soup matches that reflected in the genebank,
and that various counts are internally consistent within the genebank.

5) Garbage Collection

     Routines have been added which clean-up the genebank once per million
exectued instructions.  Among other things, once a size class is extinct,
all genomes of that size are eliminated from RAM.  Permanent genomes are first
saved to disk.

6) New genomes distributed

     Many new genomes were first distributed with V3.1, but they were not
mentioned in the announcement.  These are the genomes of most of the
creatures described in the publications and videos: parasites,
hyper-parasites, social creatures, cheaters, etc.

7) Opcode mneumonics limited to six characters

     To facilitate their display by the Beagle tools, the opcode mneumonics
have been limited to six characters.  This affects push_ax, push_bx, push_cx,
push_dx, and mov_iab.  These have been changed to pushax, pushbx, pushcx,
pushdx and moviab.  This means that old ascii genome files can not be read
by the new tools.  It does not affect binary genome files.  Old binary files
will be mapped to the new names when they are converted to ascii by the new
software.  All the ascii .tie files are redistributed in the new format.

8) Virtual Extraction

     When a new genotype crosses one of the thresholds (SavThrMem or
SavThrPop) its name becomes permanent and it is ``extracted'' (written to
disk).  This event is noted in the user interface and in the tierra.log
file like: ex = 0079aaa @ 13
The new feature is that when a genotype goes extinct, then reappears and
crosses the thresholds again, it experiences a ``virtual extraction'',
which means that it is not written to disk (since it is already there),
but the extraction event is written to the interface and the tierra.log
file like: ex = 0079aaa @ 13 v
This was done to facilitate the use of the tieout tool with cumulative
genebanks, but it results in nicer extraction data in other senses as well.

9) Grant from Digital Equipment Corporation

     The Semiconductor Engineering Group of Digital Equipment Corporation has
donated two fully loaded DS5000 workstations to the Santa Fe Institute as a
part of a grant to Tom Ray titled: ``Computer Architectures for the Natural
Evolution of Machine Codes''.  These two machines will be the primary platform
for Tierra research and development in the near future.

10) Future Sex

     Walter Tackett (tackett@ipld01.hac.com or tackett@priam.usc.edu)
has implemented haploid sex based on cross-over (a random cross-over point
used by the moviab instruction) in his private copy of Tierra V3.0.  The
methodology used by Tackett has been implemented in the Santa Fe verison of
Tierra.  It will be released when it has undergone more testing to verify its
functions.

BIOCOMPUTATION WORKSHOP
Evolution as a computational process
June 22-24, 1992
Doubletree Hotel
2 Portola Plaza
Monterey, Ca 93940

Sponsored by the Institute for Scientific Computing Research at LLNL and
the Center for Computational Engineering at SNL

This workshop brings together biologists, physicists and computer
scientists with interests in the study of evolution.  The premisis
of the workshop is that natural evolution is computational process
of adaption to an ever changing environment.  Mathematical theory and 
computer modeling are therefore ideally suited to study evolution
and conversely, evolution may be used as a model system to study the 
computational processes of optimization and emergent pattern formation.

Fifteen invited speakers will provide general reviews and summaries of their
recent research.  Although oral presentations will be limited to the invited
speakers, original research contributions are solicited for poster sessions 
in the following areas:

natural evolution
artificial life
genetic algorithms and optimization

      IWANN'91 (International Workshop on Artificial Neural Networks) was held
 in Granada (Spain) in September 1991. People from over 10 countries attended
 the Workshop, and over 50 oral presentations were given.

      IWANN'93 will be organised next June, 1993 in Sitges (Spain) with the 
following Scope and Topics.

                                SCOPE

      Artificial Neural Networks (ANN) were first developed as structural or 
functional models of biological systems in an attempt to emulate their unique
problem-solving abilities.

      The main interest in neural topics stems from their advantages in 
plasticity, speed and autonomy over conventional hardware and software, which 
have traditionally proven inadequate for handling certain tasks such as 
perception, learning, planning, knowledge acquisition and natural language 
processing.

      IWANN's main objective is to offer a forum for achieving a global, 
innovative and advanced perspective on ANN. In addition to conventional Neural
Networks aspects, such as algorithms, architectures, software development tools
, learning, implementations and applications, IWANN'93 will also be concerned 
with other complementary topics such as neural computation theory and 
methodology, physiological and anatomical basis, local computation models, 
organization and structures resembling biological systems.

      Contributions on the following aspects are welcome:

           * New models for biological networks.

           * New algorithms and architectures for autonomy and self-
	     programmability using local learning strategies.

           * Relationship with symbolic and knowledge-based systems.

           * New implementation proposals using general or specific processors.
           Implementations with embedded learning are especially invited.

           * Applications.

      Finally, it is expected that IWANN'93 will also serve as a meeting point
for engineers and scientists to establish professional contacts and 
relationships.

                                TOPICS

       1 -  BIOLOGICAL PERSPECTIVES: anatomical and physiological basis, local
            circuits, biophysics and natural computation.

       2 -  THEORETICAL MODELS: analog, logic, inferential, statistical and 
            fuzzy models. Statistical mechanics.

       3 -  ORGANIZATIONAL PRINCIPLES: network dynamics, self-organization,
            competition, recurrency, evolutive optimization and genetic
            algorithms.

       4 -  LEARNING: supervised and unsupervised strategies, local self-
            programming, continuous learning, evolutive algorithms

       5 -  COGNITIVE SCIENCE AND AI: perception and psychophysics, symbolic
            reasoning and memory.

       6 -  NEURAL SOFTWARE: languages, tools, simulation and benchmarks.

       7 -  HARDWARE IMPLEMENTATION: VLSI, parallel architectures,
            neurochips, preprocessing networks, neurodevices,
            benchmarks, optical and other technologies.

       8 -  NEURAL NETWORKS FOR SIGNAL PROCESSING: preprocessing, vision,
            speech recognition, adaptive filtering, noise reduction.

       9 -  NEURAL NETWORKS FOR COMMUNICATIONS SYSTEMS: modems and codecs, 
            network management, digital communications.

       10 - NEURAL NETWORKS FOR CONTROL AND ROBOTICS: system identification,
            motion, adaptive control, navigation, real time applications.

                              LOCATION

               SITGES (BARCELONA), JUNE 9 - 11, 1993.

      Sitges is located 35 km. south of Barcelona. The city is well known for
its beaches and its promenade facing the Mediterranean sea. Sitges is also 
known for its cultural events and history (Maricel museum, painters like 
Santiago Rusinol lived there and left part of their heritage).

      Sitges can be easily reached by car or by train (about 30 minutes from 
Barcelona).

From: "Barry McMullin, DCU (Dublin, Ireland) <75008378@DCU.IE>"
Subject: Workshop: "Autopoiesis and Perception" - Call for Participation.

[The workshop announced below addresses an essentially cross-
disciplinary subject area, potentially involving philosophy, computer
science, engineering and biology - to name but a few.  It is therefore
being posted across a variety of forums (fora?): so my apologies for the
noise if you see it more than once!  All flames directly to me, please.
In case you wish to print out the plain ascii text, it has been
structured with 72 columns, 66 lines per page.  Please pass on the
notice to anyone else who may be interested.  If you require further
information, or wish to register, please follow the instructions below;
but note that, due to other commitments over the next fortnight, no
acknowledgements will be issued before May 27th. - Barry.]

                       AUTOPOIESIS AND PERCEPTION
                    A Workshop within ESPRIT BRA 3352
                DUBLIN CITY UNIVERSITY: 25-26 August 1992

            ************  CALL FOR PARTICIPATION ************

A common sense idea of perception is that, through the information
processing capabilities of our sensory/brain system, we come to know
"the" objectively real, external, world. However, this "spectator"
paradigm has not proved very effective (so far) in attempts to build
artificial perceptual systems. It therefore seems appropriate to
critically examine this concept of perception.

One alternative idea is to take a participatory rather than a spectator
view of the relationship between "us" and "the external world". To
perceive is not to process sensory data, but to apprehend meaning
through interaction.

Autopoiesis is an organizational paradigm which can support such a
participatory view of perception. The concept of autopoiesis (lit.
"self-producing"), was introduced to characterise the organisation which
makes living systems autonomous. An autopoietic organisation is one
which is self-renewing (in a suitable environment); autopoietic systems
maintain their organisation through a network of component-producing
processes such that the interacting components generate the same network
of processes which produced them. In the autopoietic paradigm,
perception is an emergent phenomenon characteristic of the interaction
between an autopoietic system and its environment: the system responds
to perturbations in just such a way as to maintain its (autopoietic)
identity.

Structure:
----------

The key objective of the workshop is to allow for extensive, open,
discussion, and it has been structured accordingly. It will consist of a
small number of prepared papers by invited keynote speakers, punctuated
with extended discussion periods; it will run over one and a half days
(from 9.30 AM on 25th August, to 1.00 PM on 26th August). To
maximize the benefit of the discussion, the workshop will be
limited to 30 participants.

Invited Speakers (Confirmed):
