15 teams entered the 2009 TAC AA competition. The finals were held over two days at IJCAI 2009 in Pasadena, California. After a semi-final round (won by TacTex), the top eight agents advanced to a final round consisting of 80 games. TacTex won the final round with an average score of $79,886. The plot on the right shows the average daily balance of the top four agents. Here we have subtracted 1293 per day (the average daily profit of the second place agent) from each balance to improve visibility -- otherwise the plot would appear as nearly diagonal lines. The oscillations are due to the way in which a capacity limit is implemented in the game. TacTex pulls away during the second half of games, possibly due to improving price predictions, and ends on an upswing as a result of planning ahead.
