                            FINAL CIRCULAR

THE CONFERENCE THEME

Complex systems are systems dominated by non-linearity or interactions
between their components. The last few years have seen an extraordinary
growth of interest in complex systems.  The underlying theme for this
conference - from biology to computation - reflects trends that have
been apparent in both biology and computer science.

On the one hand biologists have begun to accept the limitations of the
reductionist approach and have started investigating emergent
properties.  One of the most potent paradigms linked with this new
approach is the notion of life as a form of computation. This paradigm
finds its ultimate expression in the new field of "artificial life".

On the other hand computer scientists, trying to discover how to
organize the workings of massively parallel computers, quickly realized
that they need to look at existing multiple processors. i.e. living
organisms. This search, long apparent in the field of artificial
intelligence, has focussed chiefly on neural networks. However, the
lessons of biology are now being applied more and more widely, such as
in the introduction of genetic algorithms.

The theme of this conference, then, reflects the dual notions of life
as natural computation and computation as artificial life. The papers
cover fields from artificial life to parallel computers including
neural networks and social systems.

Please pass on this notice to interested colleagues. For further
information contact the conference secretary or the convenors.

KEYNOTE SPEAKERS

Geoffrey Fox       "Advances in parallel computing"

Professor Fox (Syracuse) is one of the world's leading authorities on
parallel computers. At Caltech during the 1980's he pioneered the
hypercube multiprocessor.  He currently heads the Northeast Parallel
Architecture Centre at Syracuse University.

Walter Freeman     "Parallel computation in biological systems"

Professor Freeman (Berkeley) pioneered the study of complex behaviour
in neural systems, with extensive published work in this field going
back over two decades. His extensive biological studies are now
yielding novel algorithms for machine pattern recognition.

Paulien Hogeweg     "As large as life and twice as natural:
		     Bioinformatics and the artificial life paradigm"

Professor Hogeweg (Utrecht) pioneered the study of informatic processes
in biotic systems.  She has modelled self-organization in a vast range
of biological systems, including prebiotic molecular evolution, cell
signalling in the immune system, and the emergence of social behaviour
in insect colonies.



TUTORIAL

On Sunday 13 December, from 10:00am-5:00pm, there will be an
introductory practical tutorial on Complex Systems. The tutorial will
cover basic ideas about:

      chaos, fractals, IFS codes, L-systems, cellular automata,
      neural networks, parallel computing.

Practical sessions on PCs and workstations will provide participants
with a hands-on introduction to each topic. It is planned to include
demonstrations running on ANU's Connection Machine supercomputer.

Enrolments for the tutorial are strictly limited; acceptance will be on
the basis of first-come, first-served.  The enrolment fee of $100 will
cover tuition, lunch, refreshments, notes and selected software.  The
venue for the tutorial will be the Computer Services Centre, Australian
National University.  To obtain further information tick the box
provided on the registration form or contact the conference
organizers.


WORKSHOPS

On Wednesday December 16, immediately following the conference, there
will be several advanced workshops.  The workshops planned so far
include Neural Dynamics, The State of the Art in Parallel Computing,
and Artificial Life.  The fee of $35 includes lunch and refreshments.
