	     First European Conference on Artificial Life
	     Toward a practice of Autonomous Systems

	     to be held in Paris, 11-13 December 1991

    The intention of Artificial Life is to build artificial systems
    exhibiting life-like behavior and to advance the theory as well as
    research of biological phenomena. Artificial life extends the
    traditional themes of artificial intelligence, such as perception and
    learning, to broader biological properties related to adaptability and
    viability. The focus is on simulations with bottom-up more than
    top-down modelling, with local rather than centralized controls,
    simple rather than complex specifications, and emergent rather than
    prespecified behavior.

    The purpose of the Conference is to bring together a selected group of
    researchers for an in-depth discussion of recent research. The focus
    will be on the simulations, theories and algorithms that shed light on
    the basis of autonomous capacities of living systems at all levels.
    The following topics are indicative of chosen orientations, but are
    not meant to be exclusive :

    Artificial animals Artificial ecologies     Emotion and Motivation
     Genetic algorithms     Immunologic algorithms  Neural Networks Autonomous
    systems  Self-adapting systems  Co-evolution  Emergent
    behaviors     Emergent structures Fitness Landscapes.

    A second focus of this Conference will be the epistemological, ethical
    and historical issues raised by Artificial Life in general and
    autonomous systems in particular. Thus, apart from scientific
    contributions, a certain number of papers dealing with these
    reflections are welcome. Clarification of broad but important notions
    such as self-adaptive, resilient, viable, etc.. are particularly
    requested.

Subject: TRANSPUTING '91 Genetic Algorithms Tutorial

   I gather that the genetic algorithms mailing list recently received a
   slightly over-edited announcement of the AI tutorial due to be presented
   in April at the TRANSPUTING '91 conference.  More complete details are 
   included below.

				TRANSPUTING '91

			       22 - 26 April 1991

		       Sunnyvale Hilton Inn, California

   Transputers are the revolutionary microprocessors for multiprocessing
   which have outsold all other 32-bit RISC architectures.  They are fuelling
   explosive growth in science and engineering by extending the ability to
   solve complex problems fast, elegantly and at reasonable cost.

   Highlights of TRANSPUTING '91 will include :

   *  A complete technical disclosure of the next generation INMOS H1
      transputer, which will offer 150 MIPS and 20 MFLOPS peak performance.

   *  Five invited speakers from the U.S.A., the U.K. and Japan.

   *  67 contributed papers, fully-refereed and selected to present a wide
      range of parallel processing techniques, applications and experiences.

   *  A wide ranging tutorial program which will be invaluable as an
      introduction to multiprocessing hardware and software techniques, as
      well as more advanced material in specific application areas, such as
      artificial intelligence.

   *  An exhibition of transputer products from 20 vendors worldwide.
      Non-commercial demonstrations of transputer applications will also be 
      present.

   TRANSPUTING '91 builds upon the previous successful meetings of the
   many Transputer and Occam User Groups worldwide, and is being organized
   by representatives of these Groups - the World Transputer User Group
   Committee.

   As well as three days of conference sessions, two days are set aside for
   tutorials.  These tutorials are being provided by experienced members of
   the transputer community as an inexpensive educational service for
   delegates to TRANSPUTING '91.  All will attempt to provide a practical
   guide to the topics presented, so that attendees may rapidly apply the
   knowledge gained.



   The Artificial Intelligence Tutorial
   ====================================

   This will run all day on Friday, April 26th, 1991.  

   Organised by : J. Stender & E. Hillebrand (Brainware GmbH, Germany)
   Presented by : S. Forrest (University of New Mexico, U.S.A.),
		  D. Macfarlane & I. East (University of Buckingham, U.K.)


   The morning session of the workshop will provide an introduction and
   overview of parallel genetic algorithms, and it will discuss fine-grained
   parallel genetic algorithms.  The session will be divided into three
   roughly equal parts:

   1. Introduction and overview of (sequential) genetic algorithms

   -    introduction (biology or computer science?)
   -    mechanical details of the algorithm
   -    why genetic algorithms work
   -    example applications

   2. Theory of parallel genetic algorithms

   -    implicit parallelism
   -    explicit parallelism of population subdivision
   -    interactions among subpopulations
   -    explicit fine-grained parallelism

   3. Fine-grained parallel genetic algorithms

   -    one processor per individual model
   -    replication strategies (conventional, location-based, resource-based,
	pattern-based)
   -    implementation issues
   -    research questions
   -    example applications


   The afternoon session of the workshop will focus primarily on the practical
   aspects of implementing genetic algorithms on transputer networks.  Many of
   the issues raised, such as scalability, load balancing, efficiency and
   deadlock freedom, have more general application in parallel processing.

   The session will be divided into four parts of approximately equal length.

   -    General issues in scalable efficient implementations of fine-grained
	parallel genetic algorithms on coarse grained transputer networks.

   -    Three parallel genetic algorithms, farming, migration and diffusion,
	and their implementation on transputer networks.

   -    Applications and studies of parallel genetic algorithms.  Evaluation
	and comparison of the different models and implementations.

   -    Demonstration of implementations and visualisation software.
	Question time.

   The workshop will draw on work done in Europe using transputers and
   parallel genetic algorithms and in particular the ongoing research at
   Buckingham Univerity in the UK and GMD in Germany.  Two major applications
   of parallel genetic algorithms will be described, the solution of TSP
   problems and the search for application specific structured neural
   networks.

   Attention will also be drawn to the practicality and cost effectiveness of
   transputer networks used in conjunction with the occam programming
   language.
