TAC 2006

TAC 2006 consisted of two separate competitions: TAC Classic / Travel focused on bidding on multiple simultaneous markets and TAC SCM focused on e-trading in a supply chain scenario. You can find the registered participants of TAC-06 here.

Finals of Trading Agent Competition 2006 was held in conjunction with AAMAS-06, Hakodate, Japan (the TADA/AMEC workshop).

Finals at AAMAS, Hakodate, Japan (9th-11th May)

The format of the final rounds are as follows:

May 9-11, TAC Travel/Classic Finals

In TAC Travel/Classic we have a fairly low number of teams, which will make it possible for all teams to qualify for the finals. Therefor the finals will be played during three days.

May 9 08:45 - 17:45 (UTC+9), TAC Travel/Classic Finals Day 1
Games played at server
May 10 08:45 - 16:45 (UTC+9), TAC Travel/Classic Finals Day 2
Games played at server
May 11 08:45 - 16:45 (UTC+9), TAC Travel/Classic Finals Day 3

May 9 08:45 - 17:45 (UTC+9), TAC SCM Quarter Finals

All teams from the seeding rounds will qualify for the quarter finals. These teams will be broken into four groups of six teams:

( Team 1 is the best scoring team in the seeding round followed by Team 2 and so on..)

Since only 21 teams will play in the quarter finals, the last three positions 22-24 will be played using a filler agent (RationalSCM-05) that will not progress to the semi finals. Thanks to team RationalSCM for letting us use their agent for this purpose!

Call For Participation


The Seventh Annual Trading Agent Competition - Call for Participation

May 9-11, 2006

Future University-Hakodate, Japan
Collocated with the Fifth International Joint Conference on Autonomous
Agents and Multiagent Systems - AAMAS-06

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

Building on the success of previous Trading Agent Competition events, we
announce the Seventh Annual Trading Agent Competition (TAC-06),  to be
held in April and early May of 2006, with the finals taking place during
the AAMAS-06 conference in Japan (May 9-11, 2006).

This event is 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 in the

1. TAC Classic/Travel - The software agents will 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 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 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.

The competition will be hosted on the SICS TAC Classic and TAC SCM
Servers available for open source download at:

Software agents communicate with the TAC Server via a TCP-based agent
programming interface.  Simple example agents are available at

The final rounds of the competition will be held during AAMAS-06 (May
9-11, 2006) preceded by qualifying and seeding rounds in April 2006.
The first day of the final rounds is also scheduled to coincide with
the Trading Agent Design and Analysis ("TADA/AMEC") workshop to be
held at AAMAS-06.

To register for TAC-06, please fill out the form at:

The entry fee will be US$250 per team to enter one game, or $400 for
