COGANN-92
A Workshop on Combinations of
Genetic Algorithms and Neural Networks
June 6, 1992
Sheraton Inner Harbor Hotel
Baltimore, Maryland, USA
Sponsored by the IEEE Neural Networks Council
with the cooperation of the International Society for Genetic Algorithms
The day before the start of IJCNN-92, a one day workshop is
scheduled on Combinations Of Genetic Algorithms and Neural
Networks. Both of these computational paradigms are inspired by
information processing schemes used by nature, but they typically
have vastly different time constants. Recently, researchers have
begun experimenting with combining them into adaptive learning and
optimization systems with new capabilities. The goal of the
workshop is to bring together researchers to share concepts,
experience and recent research results. The IEEE Computer Society
Press will publish selected papers in a post-proceedings to appear
within a few months of the workshop.

Essays on Darwinism
2: Organismic Darwinism
Barry McMullin,
School of Electronic Engineering,
Dublin City University,
Dublin 9,
IRELAND.
<McMullinB@DCU.IE>
April 1992
Technical Report: bmcm9202
{\em Artificial Life\/} is, by its nature, an interdisciplinary
research programme; it will involve biologists, of course, but
also philosophers, mathematicians, chemists, computer
scientists---and perhaps even (as in my case) engineers. Success
in our endeavours will require some of us, at least, to venture
into foreign territory. This essay is a log of my personal
expedition into evolutionary biology. I attempt to provide a
comprehensive review of Darwinism in the biological world, and to
do so as an {\em outsider\/}---a non-professional in the field.
My purpose is twofold. Firstly, I hope that real biologists may
take this opportunity to correct at least the worst of my errors.
Secondly, I offer this to other non-specialists as a sort of
map---a record of my particular exploration. I hope it might at
least provide some insight into the kinds of questions which need
to be asked, even if the particular answers suggested here are
less than satisfactory. Above all, I want to convince any who
may be in doubt that {\em Darwinism\/} encompasses a complex and
subtle system of interrelated theories, whose substantive
transplantation to any artificial medium will be very far from
easy.
This essay draws on abstract concepts introduced in a previous
essay [see .bib reference below]; the two essays are
therefore best read in conjunction.

TO OBTAIN A COPY:
[I should warn that bmcm9202 is, relatively speaking, a biggie: it
runs to just under 50 printed pages...]
Copies are available in the following ways, in order of
(my) preference:
1: ftp the file <bmcm9202.ps.Z> from directory <pub/alife/papers>
on the Alife archive <ftp.cognet.ucla.edu>, uncompress it and
then print (or preview) it. This involves doing (something like) the
following:
unix> ftp ftp.cognet.ucla.edu
Connected to ftp.cognet.ucla.edu
Name (ftp.cognet.ucla.edu:): anonymous
331 Guest login ok, sent ident as password.
Password: [identification]
230 Guest login ok, access restrictions apply.
ftp> cd pub/alife/papers
ftp> binary
ftp> get bmcm9202.ps.Z
ftp> quit
unix> uncompress bmcm9202.ps.Z
unix> lpr -P(your_local_postscript_printer) bmcm9202.ps
[Many thanks to Alife maintainer, Rob Collins, for help above and
beyond the call of duty in making this possible. If you have any
problems, complain to me not Rob.]
2: I can email the file bmcm9202.ps.Z to you, on request
(uuencoded, split into 5 by about 55k chunks). You'll have to be
able to strip off the mail headers, cat the file back together,
uudecode, uncompress, and print postscript (or preview etc.).
3: Alternatively, I can email the file bmcm9202.dvi.Z to you, on
request (again, uuencoded, split into 4 by about 55k chunks).
You'll have to be able to strip off the mail headers, cat the
file back together, uudecode, uncompress, and then do whatever
you locally do to print or preview .dvi files. Apart from being
slightly smaller, and thus use less network bandwidth, this
option, if it suits you, is probably a bit more robust than the
.ps route, as it is much less dependent on the vagaries of your
local printer...
4: Or, I can email you the LaTeX sources. This has the advantage
of being plain ascii text, so I can send it without any encoding
etc.. You can then run it through LaTeX to get a properly
formatted version; or, if you don't have access to LaTeX, the
sources are readable as they stand (just about). The disadvantage
is that you need several different files, so it is a bit messy.
5: Finally, if that's all gobbledegook to you, then a limited number of
good old fashioned hard copies will be available. Send me your
full postal address. First come first served. However, note that
Dublin is currently suffering an industrial dispute in the postal
service, so I can't promise anything about when you might receive
a hard copy---so this really is a last ditch alternative.
In cases 1 and 2, if the .ps file fails to print fully (or at
all) please let me know, including any diagnostic info. you can
provide.
In cases 2--5 contact me as <McMullinB@DCU.IE> (do *not* send
requests to the whole list...).

Subject: Parallel Problem Solving from Nature Conference
PPSN92
PARALLEL PROBLEM SOLVING FROM NATURE CONFERENCE
ARTIFICIAL INTELLIGENCE LAB
FREE UNIVERSITY OF BRUSSELS
BELGIUM
28 - 30 SEPTEMBER 1992
General Information
===================
The second Parallel Problem Solving from Nature-conference (PPSN92) will be
held at the Free University of Brussels, September 28-30, 1992.
The unifying theme of the PPSN-conference is natural computation,
i.e. the design, the theoretical and empirical understanding, and the
comparison of algorithms gleaned from nature and their
application to real-world problems in science and technology.
Examples are genetic algorithms, evolution strategies, algorithms
based on neural networks and immune systems.
Since last year there is a collaboration with the International
Conference on Genetic Algorithms (ICGA) resulting in an alternation of both
conferences. The ICGA-conferences will be held in the US during the
odd years while the PPSN-conferences will be held in Europe during the
even years.
The major objective of this conference is to provide a biannual
international forum for scientists from all over the world where they
can discuss new theoretical, empirical and implementational
developments in natural computation in general and evolutionary
computation in particular together with their applications in science,
technology and administration.
The conference will feature invited speakers, technical and poster
sessions.

Subject: Another Artificial Life Program
Re: Artificial Life Programs
After perusing through the Tierra documentation, I find that the
artificial life system I wrote at home performs many of the same functions,
but in real-time with a colorful and much more extensive operator interface.
DEVO is a program written under DOS, for a VGA color monitor. It
consists of a number of cell types, each with its own set of behaviour
characteristics and functionality, which group together to form various
organisms. These organisms vie for artificial energy in an ongoing life
and death struggle. Once a particular level of energy is reached, the
organism may reproduce.
DEVO functionality includes:
1. The ability to alter running parameters on the fly.
2. The ability to partition the life space.
3. The ability to examine, modify, and kill organisms.
4. A viewing window to move around through the virtual life space.
5. The ability to save and restore running life-cycles.
6. Runs in real-time with a rather interesting organism display.
DEVO was written for fun in my spare time at home. If there is any
interest, I may be persuaded to continue its development. Additionaly, if
there is any interest in the source code, please let me know. It's not a
piece of software to stop the world, but I think it's a good start in one of
the many directions.
Required hardware: AT under DOS. 640KB RAM. Color VGA monitor.
If only I had the time to combine this with my neural net project...
Or to create a general-purpose cell type which mutates during reproduction
occaisionaly... Or who knows...
Just to pique your interest a little more:
A few more bits and pieces of info on the DEVO program...
The cell types currently defined:
1. Energy - unit of life.
2. Motion - adds momentum to the structure in the direction
from which the energy was aquired.
3. shield - protects against energy transfers from:
4. attack - steals energy from cells of foreign organism.
5. fat - stores energy for later use.
6. reproduction - causes organism reproduction when filled.
Cells all have a different number of possible links with which to
stick together to form an organism. For instance, a reproduction cell
will establish up to
four links with other cells. Two cells may link together if first, they
occupy the same virtual space grid point, and second they both have a link
available. When cells link, the total energy of the two organisms is averaged
and becomes the new total energy of the new organism.
The upper left corner of the life space is where energy is disseminated
in random direction and velocity. Thus very little energy ever makes it to the
furthest point in the life space (the lower right corner).
The user may build barrier walls to alter the form and shape of the
life space. One such use is to capture an organism near the energy source
to force its reproduction.
Two types of wall blocks are defined:
1. bounce - cells bounce off back in the direction they came.
2. death - causes instant death of entire organism.
Organisms continually lose energy and velocity. Energy is continually
pumped into the system. Velocity is created via the motion cells.
When an organism's energy level hits zero. It is killed. All the
links between its cells are broken, they are given random small amounts
of energy, and random directions and velocity. The organism literally
explodes. (Fun to watch!)
Inactive cells are kept on a free list. When the free list gets
below a certain level, killed cells are placed here. When an organism
wishes to reproduce, the new cells it needs are taken from here.
The devo program provides a viewing window into a virtual life space,
the life space being much larger than the screen. The user may move
this viewing window around in the life space while the program is running
to see what is going on in different areas.
The virtual life space is composed of a two dimensional array of
grid points. Each grid point represents an 8*16 patch of real spatial points.
Cells within the same grid point are kept in a linked list for that grid
point. When a cell moves enough to change grid points, it is relinked into
the appropriate new grid point linked list. This enables
extremely fast neighbor checking. I.E: I don't have to search through the
entire set of cells to find who is next to whom for interactions, I already
know who the neighbors are.
A status screen is provided to track number of births, deaths,
number of cells on the free queue...
A screen is provided to alter a number of the running parameters,
such as the amount of energy in an energy cell, the maximum size of an
organism, how fast to remove velocity from the system...
A file save/restore screen is provided so that a life space may
be saved and restored.
A single-step or free-running option is available.
A cursor is provided so that one may view the contents of any cell.
DEVO runs in real-time, in graphics mode on the VGA. And since the
life space is always changing, and there is no disk access while the
program is running, if nothing else it makes for an interesting screen
saver. :)
There are many more things I'd like to add. But theres that nagging
little problem of finding the time... :(

Subject: The Interpersonal Computing and Technology List (IPCT-L)
IPCT-L on LISTSERV@GUVM
or LISTSERV@GUVM.GEORGETOWN.EDU
The Interpersonal Computing and Technology List (IPCT-L) was
created February 1992 by the Center for Teaching and Technology (CTT)
at the Academic Computer Center, Georgetown University. A special
effort will be made to promote an international forum for
pedagogical issues important to higher education involving
teaching with technology, and especially with connectivity and
networking.
A goal is to create a forum for the discussion of computing and
other technology that can be used to promote learning. Topics for
discussion may involve teaching and training; collaboration;
partnerships among learners, faculty or teachers, and other
interested persons in the educational community; and research that
reflect these interests. The decade of the 1980s was characterized
by the _personal_ computer, and development of individual product-
ivity. The focus of the IPCT-L, as we move toward the 21st century,
is that _interpersonal_ computing and technology will tie persons
together throughout the world -- to share ideas and solve problems.
Besides creating a forum for the topics of interest noted above,
another interest of the CTT is to publish a scholarly, refereed
international journal. To that end, the IPCT-L will develop a
subscription list and act as a resource to develop the community
necessary to review articles and recommend editorial policies as
these publishing goals move forward.

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:
