The article by Shoham, Powers, and Grenager called 'If multi agent learning is the answer, what is the question? does a great job of laying out the current state of the art and open issues at the intersection of game theory and artificial intelligence (AI) However, from the AI perspective, the term 'multiagent learning' applies more broadly than can be usefully framed in game theoretic terms. In this larger context, how (and perhaps whether) multiagent learning can be usefully applied in complex domains is still a large open question.
