Just a few notes that may be of interest to researchers interested in agent-based computational economics (ACE), the computational study of economies modelled as evolving decentralized systems of autonomous interacting agents. Items of more permanent interest will be retained at the ACE Web site at
Items currently available at this ACE Web site include: an annotated syllabus of ACE-related readings; ACE surveys; pointers to other Web sites containing ACE-related materials; a list of hotlinks for ACE-related software; and ACE-related conference notices.
ACE news notes are anticipated about once every month or so during the regular academic year, September-May. Please contact Leigh Tesfatsion (email@example.com) if you wish to be added or removed from this news list, or if you have items you wish to have included in the news notes. Please do **not** use the list address.
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx 1. Change in ACE Web Site Address Please note that the new ACE Web site address is http://www.econ.iastate.edu/tesfatsi/ace.htm *** For obvious reasons, "abe" has been replace by "ace." xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx 2. New European/Germany ACE Site A European/German Page on ACE is now being maintained by Torsten Eymann of the University of Freiburg in Germany. This interesting and informative site complements the U.S.-based ACE Web site that I maintain by providing detailed information on ACE-related events, people, and projects in Europe, with a particular focus on Germany. The Web site address is http://www.iig.uni-freiburg.de/~eymann/ace.htm xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx 3. A More Official Outlet for ACE News Notes Dan Ashlock (Math Dept, ISU) and I have accepted invitations to be the co-editors in charge of the Complexity-at-Large section of _Complexity_, a John Wiley bi-monthly cross-disciplinary journal focusing on complex adaptive systems. [See item 4, below, for the _Complexity_ home page address.] Our specific charge is to gather together and present news items of interest to the _Complexity_ journal readership at large. These news items may include new book release notices and/or reviews, new software notices and/or reviews, conference reports, technological applications,...etc. Dan will primarily focus on biological and physical systems, while I will focus more on items relating to social and socio-economic systems. Both of us will also keep an eye out for interesting items of a more abstract nature. In particular, then, any news items submitted to me for the ACE news notes will henceforth also automatically be considered for inclusion in the Complexity-at-Large section of _Complexity_. I welcome your input. xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx 4. Established Journals Interested in ACE-Related Research Below is an alphabetical listing of established journals that specialize in topics of particular interest to ACE researchers and that have Web sites with subscription and manuscript submission information. Note: A list of hotlinks to these journals can be found at the ACE Web site (syllabus page). (a) _Adaptive Behavior_ http://mitpress.mit.edu/journal-home.tcl?issn=10597123 (b) _Artificial Life_ http://mitpress.mit.edu/journal-home.tcl?issn=10645462 (c) _Complexity_ http://journals.wiley.com/1076-2787/ (d) _Computational Economics_ http://kapis.www.wkap.nl/kapis/CGI-BIN/WORLD/journalhome.htm?0927-7099 (e) _Evolutionary Computation_ http://mitpress.mit.edu/journal-home.tcl?issn=10636560 (f) _Games and Economic Behavior_ http://www.apnet.com/www/journal/ga.htm (g) _IEEE Transactions on Evolutionary Computation_ http://www.ieee.org/society/nnc/pubs/transactions.html (h) _Journal of Economic Behavior and Organization_ http://www.elsevier.com/locate/jebo/ (i) _Journal of Evolutionary Economics_ http://link.springer.de/link/service/journals/00191/ (j) _Macroeconomic Dynamics_ http://wuecon.wustl.edu/~barnett/MD.html xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx 5. Two New Journals Interested in ACE Research Another journal interested in ACE related research is _Journal of Public Economic Theory_, new from Basil Blackwell. [I know this because I am an associate editor.] No Web site is yet available for this journal; contact the editor John Conley (firstname.lastname@example.org) for submission information. Finally, another new journal that might be a good outlet for ACE research is _Automous Agents and Multi-Agent Systems_, new from Kluwer. For more information about this journal, contact the Executive Editor Nicholas Jennings (N.R.Jennings@qmw.ac.uk) at Queen Mary and Westfield College, University of London, or Mrs. Karen Cullen (email@example.com) at the Kluwer Editorial Office in Norwell, Massachusetts. Some information about the journal may also be found at the Kluwer Web site at http://www.wkap.nl/ xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx 6. New Announcements for ACE-Related Conferences Note: A list of hotlinks for these conferences can be found at the ACE Web site (conference page). The Second International Conference on Autonomous Agents (Agents'98) will be held in Minneapolis/St. Paul, Minnesota, May 10--13, 1998. A pre-conference one-day workshop will be held on May 9 on the topic "Artificial Societies and Computatational Markets." The due date for paper submissions for this workshop is January 15, 1998. For more information, contact the Workshop Chair Grigoris Karakoulas
, CIBC and University of Toronto, Canada. The Eighth International Symposium on Dynamic Games and Applications will be held July 5-8, 1998, at the Chateau Vaalsbroek, Maastricht, the Netherlands. This Symposium is sponsored by IEEE-CSS, IFAC, and INRIA. Among the planned topics are learning and adaptive games, evolutionary games, and cooperative equilibria. The deadline for submission of papers and invited sessions is January 2, 1998. For more information, contact Ephie Deriche xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx 7. New and Improved Software Available for the Trade Network Game Note: A list of hotlinks for all software and other items mentioned below can be found at the ACE Web site (software page). The Trade Network Game (TNG) combines evolutionary game play with preferential partner selection in the context of various user-specified buyer-seller markets. C++ source code and executable files for Version 104 of the TNG are now available for downloading in a zip file (135K). A text file of instructions for downloading, unzipping, and running TNG (Version 104) is also available. Modifications made to the online TNG program, as indicated by changed version numbers, are explained in a script file. Briefly, TNG (Version 104) now includes separate evolution of distinct trader types (pure buyers, buyer-sellers, and pure sellers). It has also been designed to be portable across all 32-bit hardware, and the configuration file and default print statements have been modified to be more user friendly. Included in the TNG program are supporting classes from SimbioSys, a C++ library of abstract base classes developed by David McFadzean for the general agent-based evolutionary simulation of both biological and social systems. A detailed description of SimBioSys is given in David McFadzean's 1995 Master's Thesis from the University of Calgary. This thesis and/or the entire SimBioSys class library can be separately downloaded. xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx 8. Request for ACE and ACE-Related Software Since the last ACE news notes, a number of additional hotlinks have been added to the software page linked to the ACE Web site. However, apart from TNG (Version 104) described in item 7, above, these hotlinks are for general alife software. If you have ACE related software that is at least at the beta testing level---i.e., no compilation or run-time errors and no known implementation errors---and if you have this software publicly available for downloading from a Web site, please let me know and I will add a hotlink to your software on the ACE Web site. I personally believe that it is particularly important at this stage in the development of ACE that we make available our software so that others (particularly students) can experiment with it and can suggest or even make further improvements. Thanks for your help. xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
