Call For Participation


The Tenth Annual Trading Agent Competition – Call for Participation July 13 – 15, 2009

Pasadena, CA, USA Collocated with IJCAI-09

Trading in electronic markets is increasingly becoming both a commonplace economic activity and a topic of special interest within the AI, Electronic Commerce, and Multiagent Systems (MAS) research communities.

We invite you to participate in the Tenth Annual Trading Agent Competition (TAC-09), to be held in June and July of 2009, with the finals taking place during the IJCAI-09 conference in Pasadena, preceded by qualifying and seeding rounds in June and July.

Building on the success of previous Trading Agent Competition events, this year’s event is again designed to spur research on common problems, promote definitions of benchmarks and standard problem descriptions, and showcase current technologies.

The competition will pit software agents—developed by research groups, students, and others from all over the world—against each other in challenging market games. This year, there will be two games, and two related challenge events:

1. TAC Ad Auctions (AA). In the new TAC/AA game, agents representing Internet advertisers bid for search-engine ad placement over a range of interrelated keyword combinations. A back-end search-user model translates placement over each simulated day to impressions, clicks, and sale conversions, yielding revenue for the advertiser. Advertiser strategies combining online data analysis and bidding tac tics compete to maximize profit over the simulated campaign horizon.

2. TAC Market Design (reverse TAC, or “CAT”). CAT software agents represent market makers whose goals are to attract potential buyers and sellers as customers, and then to match buyers with sellers. The market makers compete with one another in doing this, such as the London Stock Exchange competes with the NYSE for the business of stock traders.

3. TAC Supply Chain Management (SCM). TAC/SCM simulates a dynamic supply chain environment where agents compete to secure customer orders and components required for production of these orders. The game captures many of the complexities of actual supply chains, where both demand and supply fluctuate and each manufacturer has limited production capacity. Participants also have the option of entering two SCM Challenge events: a Procurement Challenge and a Prediction Challenge.

The market games have been specially designed to present agents with difficult decision problems and admit a wide variety of potential bidding and negotiation strategies.

Preliminary documentation and software for participating in the AA Tournament are accessible at:

Preliminary documentation and software for participating in the CAT Tournament are accessible via sourceforge. Access details and other CAT information is available at:

Documentation and open source software for participating in TAC SCM, including servers and sample agents, are available for download at:

The qualifying and seeding rounds will be held in June and July, and the first day of the final rounds is scheduled to coincide with the Trading Agent Design and Analysis (TADA) workshop to be held at IJCAI-09.

To register for TAC-09, please fill out the registration form at:

The entry fee will be US$250 per team to enter one game, or $400 for all TAC games. For TAC SCM the entry fee is the same independently of the number of challenge events in which a team competes.

The entry fee is waived for teams who send a representative to the TAC finals at IJCAI-09, if that representative registers for the TADA workshop. A given individual may represent one team for one game.

Note: Please send any questions regarding the fees to tac [at] Groups unable to afford the entry fee may also contact tac [at] for special consideration.

Exact dates for the qualifying and seeding rounds will soon be posted on this site.
