The core of *ATTac-2001*'s entertainment-ticket-bidding strategy is again a
calculation of the expected marginal values of each ticket. For each
ticket, *ATTac-2001* computes the expected value of having one more and one
fewer of the ticket. These calculations give bounds on the bid and
ask prices it is willing to post. The actual bid and ask prices are a
linear function of time remaining in the game: *ATTac-2001* settles for a
smaller and smaller profit from ticket transactions as the game goes
on. Details of the functions of bid and ask price as a function of
game time and ticket value remained unchanged from
*ATTac-2000* [Stone, Littman, Singh, KearnsStone
et al.2001].

Details of the entertainment-ticket expected marginal utility calculations are given in Table 9.
