On the Complexity of Solving Markov Decision Problems
  Markov decision problems (MDPs) provide the foundations for a number of
problems of interest to AI researchers studying automated planning and
reinforcement learning. In this paper, we summarize results regarding the
complexity of solving MDPs and the running time of MDP solution algorithms. We
argue that, although MDPs can be solved efficiently in theory, more study is
needed to reveal practical algorithms for solving large problems quickly. To
encourage future research, we sketch some alternative methods of analysis that
rely on the structure of MDPs.
