Solving classic NES games computationally

Dr. Tom Murphy VII gave a research paper called "The First Level of Super Mario Bros. is Easy with Lexicographic Orderings and Time Travel . . . after that it gets a little tricky," (PDF) (source code) at SIGBOVIK 2013, in which he sets out a computational method for solving classic NES games. He devised two libraries for this: learnfun (learning fuction) and playfun (playing function). In this accompanying video, he chronicles the steps and missteps he took getting to a pretty clever destination.
