                               Call for Papers

           SIMULATION OF ADAPTIVE BEHAVIOR: FROM ANIMALS TO ANIMATS

                An International Conference to be held in Paris
                            September 24-28, 1990


        The object of the conference is to bring together researchers in
        ethology, ecology, cybernetics, artificial intelligence, robotics,
        and related fields so as to further our understanding of the behaviors
        and underlying mechanisms that allow animals and, potentially,
        robots to adapt and survive in uncertain environments.

        The conference will focus particularly on simulation models in
        order to help characterize and compare various organizational principles
        or architectures capable of inducing adaptive behavior in real or
        artificial animals.

        Contact among scientists from diverse disciplines should contribute
        to better appreciation of each other's approaches and vocabularies,
        to cross-fertilization of fundamental and applied research, and
        to defining objectives, constraints, and challenges for future work.

        Contributions treating any of the following topics from the
        perspective of adaptive behavior will receive special emphasis.


   Individual and collective behaviors   Autonomous robots
   Action selection and behavioral       Hierarchical and parallel organizations
    sequences                            Self organization of behavioral
   Conditioning, learning and induction   modules
   Neural correlates of behavior         Problem solving and planning
   Perception and motor control          Goal directed behavior
   Motivation and emotion                Neural networks and classifier
   Behavioral ontogeny                    systems
   Cognitive maps and internal           Emergent structures and behaviors
    world models


        Authors are requested to send two copies (hard copy only) of a
        full paper to each of the Conference chairmen:

Although I missed this years Genetic Algorithm Conference (I think it
was held in june), I would like to buy the proceedings. Are they
already available and if so by whom ? 

Thanx a lot,

Patrick

From: lucasius@wn2.sci.kun.nl <lucasius@sci.kun.nl>
Subject: GAs for Chemistry

At the moment I am experimenting with an application of GA's on the
determination of physico-chemical parameters, such as analyte concen-
trations and extinction coefficients, from titration datasets.  This
way many parameters can be determined at once.  However, the problem
encountered here is that many of these parameters are quite correlated.
Since correlations may, of course, be seen as a special case of multi-
modality, I've tried sharing operators with different settings, to cope
with this problem.  Unfortunately the results are not always astonishing.
Does anyone have any suggestions or could someone provide any pointers
to papers concerning this type of problem?  Thank's in advance.

Subject: Grad Schools and RA positions

What are some good schools for a MS and PhD in CS (Spec. in GA and other
machine learning, i.e. NN)?

Notice I say "good" and not "great".  What I am looking for is not the
best schools such as CMU, MIT, etc.

Also any researchers out there have any RA positions open?

From: g523116166ea@deneb.ucdavis.edu (R.Goldthwaite)
Subject: Teaching GAs

Don't know if it qualifies as "teaching GA in AI", but I picked up my copy
of Goldberg's book last spring at the Stanford campus bookstore, where it
was marked as "required" for course CS 426 in computer science, along
with Davis's 1986 book on GA and simulated annealing, Holland's 1975 book, 
and a MYCIN text.  The instructor was Dr. Koza (whom I don't know).

I've used reading from INDUCTION for a seminar in Animal Behavior, but that's
a separate issue... (and definately not a trend!).

Subject: Implicit Parallelism

I'm looking through Goldberg's book on GAs at the moment, and am having
great difficulty in understanding his explanation of the "widely quoted ...
but poorly understood" counting of useful schemata processing O(n^3). Does
anyone have a better explanation? Or one with the gaps filled in?

Also, does anyone have more information on the workshop to be held in Glasgow on
9th May 1990?

Many thanks in advance for help - George Bolt

[ Moderator's Reply:

One version of the n^3 count appears in the Appendix to "Genetic
algorithms in noisy environments", by Fitzpatrick & Grefenstette,
Machine Learning 3(2/3), Oct. 88, 101-120.  The validity of counting
schemata in this way is discussed in "How genetic algorithms work: A
critical look at implicit parallelism", by Grefenstette & Baker,
ICGA-89, 20-27.
