               Parallel Processing Specialist Group

                        One day meeting
                              on
                       CELLULAR  AUTOMATA

                        February 12 1992
                  Imperial College, London, U.K.

Introduced by von Neumann over 40 years  ago,  cellular  automata
are  receiving  renewed interest.  Cellular Automata describe the
behaviour of complex systems with very many  degrees  of  freedom
and  are  therefore  of  interest  to mathematicians, physicists,
chemists and biologists.  They may be considered as idealisations
of  partial differential equations thus enabling one to model na-
tural behaviour from turbulent flow to pattern formation  in  the
growth of organisms.
Cellular Automata also provide a complementary basis for the stu-
dies  of  systems  displaying  non-determinism and those that are
self-organising.   Analogies  with  digital   computers   provide
abstractions for the design of parallel computers.
This meeting will bring together researchers  developing  special
purpose hardware for cellular automata, software to simulate sys-
tems in the physical and biological sciences using cellular auto-
mata models and software for visualisation, among other  subjects.

Dear colleagues !

	I'm searching for literature and people working on diploid
genetic algorithms (specially, theoretical evaluation and parallel
implementation). Should you have anything on these subject I would
be grateful if you could send me information to:

Subject: Collins & Jefferson (p)reprints available for ftp

I am making several of our papers available for ftp.  They are located
in the Alife ftp site: polaris.cognet.ucla.edu:alife/papers/collins*.
Each paper has a README that gives the title, authors, where the paper
is (or will be) published, and the abstract of the paper.  These are
the Collins and Jefferson papers from Alife II, SAB90, PPSN, ICGA91,
and ECAL91.

GENERAL ASYMMETRIC NEURAL NETWORKS AND
STRUCTURE DESIGN BY GENETIC ALGORITHMS

Stefan Bornholdt

Germany.

A learning algorithm for neural networks based on genetic algorithms is
proposed. The concept leads in a natural way to a model for the
explanation of inherited behavior. Explicitly we study a simplified
model for a brain with sensory and motor neurons. We use a general
asymmetric network whose structure is solely determined by an
evolutionary process. This system is simulated numerically.
It turns out that the network obtained by the algorithm
reaches a stable state after a small number of sweeps.
Some results illustrating the learning capabilities are presented.
