1. CALL FOR SITE ADDRESSES FOR ACE-RELATED SOURCE CODE AND
   EXECUTABLE FILES

     A planned new addition to the ACE Web site is a linked list of
ftp sites and Web sites where interested researchers can obtain
source code and/or executable files for ACE-related applications.
For example, links will be included for SWARM (Langton et al.),
Sugarscape (Epstein/Axtell), SDML (Moss et al.), the Trade Network
Game (Tesfatsion/McFadzean), and SimBioSys (McFadzean).
     If you have source code and/or executable files ready for
beta testing by other users that you would like to have included in
this linked list, please send me the appropriate ftp or Web site
address along with a brief paragraph explaining the nature of the
materials available at the site.
     Unless otherwise indicated, it will be understood that any
materials available on this linked list come with a "let the buyer
beware" warning!


2. ACE-RELATED SESSIONS AT THE SUMMER 97 STANFORD CEF CONFERENCE

     Many of the invited and contributed paper sessions scheduled
for the Third International Conference on Computation in Economics
and Finance, to be help June 30-July 2 at Stanford, would appear to
be of great interest to ACE researchers.
     For example, there are two sessions on ACE, four sessions on
Evolutionary Models, three sessions on Financial Models (with many
included papers stressing ACE-related topics), as well as sessions
entitled Learning Algorithms, Simulation Models of Behavior, Models
of Learning, Models of Bounded Rationality, Dynamic Contracting, and
Computer Languages.
     A complete listing of the scheduled sessions, including
presenters and presentation titles, along with information about
registration, hotels, etc., can be found at:

3. SPECIAL ACE MEETING FOLLOWING THE REGULAR STANFORD CEF CONFERENCE

     In cooperation with Ken Judd (Program Chair), Blake LeBaron
(U of Wisconsin) and Leigh Tesfatsion (ISU) are organizing a special
meeting for researchers with a particular interest in ACE, to be
held immediately following the regular Stanford CEF Conference, from
3-5:00 P.M., Wednesday, July 2.  The ACE meeting will be followed by
an informal group dinner for all those who are interested and able
to participate.
     The original intention had been to arrange a series of
post-conference ACE workshops, but the close timing to the July 4
holiday made this infeasible.  The main purpose of the short ACE
meeting (apart from getting a chance to meet and talk with each
other) is to discuss how a coordinated track of ACE workshops might
be integrated into the regular sessions at the CEF conference to be
held in Cambridge, UK, June 29-July 1 of 1998.  Leigh Tesfatsion is
on the International Program Committee for this 1998 conference and
could relay any proposal along these lines to the rest of the
program committee members for their consideration.
      Some of the possible topic areas that might be considered
for the ACE workshops are: (a) building agent-based virtual economic
worlds; (b) agent representation; (c) ACE experimental design and
data analysis; (d) ACE models in education; and (e) applications/policy
use of ACE models.
      If you are interested in attending this ACE meeting, please
contact Leigh Tesfatsion (tesfatsi@iastate.edu).


4. NEW ACE-RELATED CONFERENCES, PUBLICATIONS, AND WEB SITES

     A variety of new announcements have been received for ACE-related
conferences (e.g., conferences in Switzerland, the Netherlands,
France, and the USA).  Summaries of these conference announcements
(together with Web site URLS for more information) have been put on
the ACE Web site.
     Similarly, a variety of interesting new ACE-related publications
have been added to the ACE/Alife syllabus, available for downloading
from the ACE Web site.  For example, a "landmark reference for
computational intelligence" was released in March 1997: _Handbook
of Evolutionary Computation_, a joint publication of the Institute
of Physics Publishing and Oxford University Press.  An interesting
aspect of this publication is that the print edition comes in the
form of a notebook that snaps open to accommodate updates published
every six months.  Interested researchers can either buy the print
edition or purchase access to an online edition.  For more
information, check out http://www.oup-usa.org/acadref/compint.html
     [Note: The policy I have converged to for inclusions in the
ACE/Alife syllabus, to keep the syllabus down to manageable length,
is that included items should either be published or forthcoming in
some type of scholarly outlet that is reasonably accessible to
interested readers.]
     Finally, a variety of new links have been added to the
"pointers to other ACE-related Web sites" section of the ACE Web
site.  Of particular interest is the recent inclusion of several
research groups with a particular interest in ACE business and
manufacturing applications.


5. ACE IN THE GENERAL MEDIA

     ACE-related research seems to be getting increased press
coverage in the general media (for better or worse).  Blake LeBaron
submitted the following:

     John Cassidy, "Chaos in Hollywood," New Yorker (March 31, 1997)
     [Focuses on work by Art De Vany and David Walls, "Bose-Einstein
     Dynamics and Adaptive Contracting in the Motion Picture
     Industry," which appeared in the _Economic Journal of the
     Royal Economic Society_ (November 1996).]

     "Artificial Adventure," _Risk_, Vol. 10, No. 3 (March 1997).
     [Focuses on work by Blake LeBaron et al. on the artificial
      stock market.]

     "The Game of Life in Bits and Bytes," _Forbes_ (April 7, 1997),
     page 100.  [Summary of agent-based models for business
     consulting.]
