Monday, May 23: Algorithm and complexity issues in discrete multistage games Michael Littman, Rutgers University A powerful formulation of the problem of decision making in a multiagent game is that each player attempts to maximize its long-term utility with respect to the behavior of the other players. I will introduce a set of related discrete models, define a solution concept for these models, and survey what is known about algorithmic approaches and the computational complexity of solving the resulting models. Tuesday, May 24: Jonathan Schaeffer, University of Alberta Poker is a challenging problem for AI research: multiple agents (up to 10), stochastic element (cards being dealt), imperfect information (don't know the opponent's cards), user modelling (identifying player patterns), and risk management (betting decisions). Wednesday, May 25: Attacker-Defender Models Matthew Carlyle, Naval Postgraduate School Bilevel programming is a natural modeling approach for situations involving conflict where there is a leader, who must make an initial decision, and a follower, who makes his decision with complete knowledge of the leader's decision. I'll illustrate the formulation and solution of large "attacker-defender" models using zero-sum bilevel programming. I'll then discuss how max-min (or min-max) soluions to these problems can inform policy and tactical decision making in such areas as counter-proliferation of WMDs, ballistic missile defense, and critical civil infrastructure protection. In all of our applications we model adversaries who are malicious and very well-informed; preparing for randomly distributed attacks or counting on a successful surprise attack is a tremendous mistake. I will conclude with comments on the value of secrecy and of deception, and how we can use our models to provide quantitative estimates of these. |
