TAC 2012 - Call for Participation

Thirteenth Annual Trading Agent Competition

on 4 and 5 June 2012 in Valencia, Spain

We invite you to participate in the Thirteenth Annual Trading Agent Competition (TAC 2012), to be held in May and June of 2012, with the finals taking place during the AAMAS-12 conference in Valencia, preceded by qualifying and seeding rounds in May and early June. You may register for the competition starting 1 February 2012 through 15 April 2012 at http://tac.sics.se/tac/intent.php.

The TAC 2012 will include four games:
  1. Power TAC. Sustainable energy systems of the future will need more than efficient, clean, low-cost, renewable energy sources; they will also need efficient price signals that motivate sustainable energy consumption as well as a better real-time alignment of energy demand and supply. In Power TAC, agents act as retail brokers in a local power distribution region, purchasing power from a wholesale market as well as from local sources, such as homes and businesses with solar panels, and selling power to local customers and into the wholesale market. Retail brokers must solve a supply-chain problem in which the product is infinitely perishable, and supply and demand must be exactly balanced at all times. - Power TAC Game Master is Wolf Ketter, Erasmus University, Rotterdam. Full documentation and software are available at http://www.powertac.org.
  2. TAC Ad Auctions (AA). In the 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. - TAC AA Game Master is Michael Wellman, University of Michigan. Documentation and software for participating in the AA Tournament are accessible at http://aa.tradingagents.org/
  3. 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. - CAT Game Master: Tim Miller, University of Melbourne. Documentation and software for participating in the CAT Tournament are accessible via sourceforge. Access details and other CAT information is available at http://www.marketbasedcontrol.com/blog/index.php?page_id=5
  4. 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. There are also two SCM Challenge events that can be run if there is a clear expressed interest: a Procurement Challenge and a Prediction Challenge; these will take place if enough teams (minimum 6) register for them. - TAC SCM Game Master: Vedran Podobnik, University of Zagreb. Documentation an open source agent framework for TAC SCM, and sample agents, are available for download at http://tac.sics.se/tac/. An updated SCM server and log-analysis tool, with examples, are available at http://tac.cs.umn.edu/controlled-server.shtml.

The qualifying and seeding rounds will be held in May and early June, and the first day of the final rounds is scheduled to coincide with TADA/AMEC, the Joint Workshop on Trading Agent Design and Analysis and Agent-Mediated Electronic Commerce workshop to be held at AAMAS'12.

To register for TAC-12, please fill out the registration form before 15 April 2012 at: http://www.sics.se/tac/intent.php

The entry fee will be US$250 per team to enter one game, or $400 for all TAC games, except that there is no fee for the Lemonade Stand Game. The entry fee (for one game) is waived for teams who send a representative to the TAC finals at AAMAS 2012, if that representative registers for the TADA workshop (in case a team participates in more than 1 game, registration cost is reduceed to US$150). Note: Please send any questions regarding the fees to tac [at] tradingagents.org. Groups unable to afford the entry fee may also contact tac [at] tradingagents.org for special consideration.

General information about TAC can be found at: http://www.sics.se/tac/

Exact dates for the qualifying and seeding rounds will soon be posted on this site, and sent to the tac-discuss mailing list. You may subscribe by sending an email to tac-discuss-request (at) umich.edu, subject "subscribe".

TAC 2006 - Press release!
Announcing the 2006 Trading Agent Competition, where teams from 15 countries will vie to maximize profits in 2 tournaments

May 4, 2006

Future University-Hakodate, Japan

Computer agents developed by 30 teams from around the world are vying to surpass each other in two particularly challenging market games, as part of the 7th Annual Trading Agent Competition (TAC-2006). Final rounds of the competition will be held at the Fifth International Joint Conference on Autonomous Agents and Multiagent Systems (AAMAS-06), which this year is taking place at the Future University in Hakodate, Japan. Qualifying rounds and seeding rounds, which took place over the past month, were just completed on May 2.

This year’s two market games are:
1. TAC Travel, where software agents represent travel coordinators whose goal is to arrange travel packages for clients. These travel packages consist of flights, hotel rooms, and tickets to entertainment events, all of which the agents buy (and, in the case of event tickets, sell) in electronic auctions.
2. TAC Supply Chain Management (SCM), which simulates a dynamic supply chain environment where agents compete to secure customer orders and components required to producethese orders. The game captures many of the complexities of actual supply chains, where both demand and supply fluctuates and each manufacturer has a limited production capacity.

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. Both games have been refined over the years through collaboration among participating research centers. TAC Travel was originally conceived by the University of Michigan and has benefited from design contributions from Brown University . TAC SCM was jointly designed by Carnegie Mellon University and the Swedish Institute of Computer Science (SICS) and has been refined in collaboration with the University of Minnesota. Both tournaments are operated through market game servers developed by SICS. The competition has also benefited from support from the US National Science Foundation.

The winner of last year’s TAC Travel competition was Mertacor, an agent developed by Prof. Pericles Mitkas and his team at the Aristotle University of Thessaloniki. The winner of last year’s TAC SCM competition was TacTex, an agent developed by Prof. Peter Stone and his team at the University of Texas at Austin. Both teams are bringing improved versions of their trading agents to this year’s tournament.

This year, hundreds of AAMAS participants are expected to follow the competition at the conference venue.
