The inaugural tournament for the Trading Agent Competition Ad Auctions game (TAC/AA) has completed. The top three most profitable teams, in order, are TacTex from the University of Texas at Austin, AstonTAC from Aston University, and Schlemazl from Brown University.

The 2009 TAC/AA competition had two basic rounds: qualifying and finals. During the qualifying round agents participates in a round-robin style tournament. Agents pass the qualifying round by meeting a minimal standard for agent competence. The TAC/AA tournament finals was held during the Trading Agent Design and Analysis (TADA) workshop as well as the main IJCAI conference in July 2009.

The tournament consisted of two stages: semifinals and finals. During each stage of the finals approximately half of the agents were eliminated, while the remaining agents continued on to the next stage. In total, fifteen teams participated in the competition with eight moving on to the final stage of the finals round. The semifinal stage consisted of a total of 88 games, while the final stage consisted of 80. Teams in the semifinal stage played in either 44 or 48 games, while all agents in the finals played in each of the 80 games.

Congratulations to all the teams that competed. The results of the competition can be found at the TAC/AA site and general information about the 2009 competition on the main TAC site.
