I ask what AI can do for games, and what games can do for AI. I want to make computer games adapt to their players through finding out what players want (whether they know it or not) and creating new game levels, challenges or rules that suit the players. Related to this is the challenge of making sense of large amounts of data generated by computer games, and on assisting human game designers in creating great game experiences. I also want to make opponents and collaborators in games more intelligent and believable, research that has applications far outside of computer games. I believe games, in particular video games, are perfect test-beds for AI methods. But it is important that you test your algorithms not just on a single game, but on a large number of games, so you focus on general intelligence and not just solving a single problem. That was the easily readable version of what I do. This is the more technical version: I'm interested in most topics in the intersection between computational intelligence and games. I currently focus on search-based procedural content generation, which means using evolutionary algorithms (or other global optimization algorithms) to search the space of game content, such as levels, maps or game rules. A key problem here is how to evaluate the candidate content, i.e. how to create a fitness function for game content. My and my colleagues attack this problem in a variety of ways, e.g. by creating theoretically founded and/or data driven models of player experience, by simulated gameplay using heuristic agents augmented by behavioural models of human players, and by measuring the performance of learning algorithms on candidate game rules. In order to do this, we need to be able to learn how to play a particular game as well as possible, and/or how to play it in a particular manner. These are interesting and worthy challenges in their own right, with additional applications to e.g. robotics. In this context, I've been working on evolutionary reinforcement learning in digital game domains, exploring techniques such as incremental evolution, competitive co-evolution and the hybridization of evolution with ontogenetic RL algorithms such as TD-learning. But it's not enough to learn well; one must know how well one learns. My contribution to fair and reliable benchmarking of RL algorithms and game AI in general takes the form of inventing and running competitions based on digital action games, such as car racing and Super Mario Bros. Recently, I have been involved in starting and organizing the General Video Game Competition, and much of my efforts currently revolve around this framework. As mentioned above, we often want to learn not only how to play a game as well as possible, but also how to reproduce a particular playing style. We might also be interested in learning other aspects of the game player, notably what game experiences she prefers. (If we know how the player plays and what she wants, we can automatically evaluate new candidate game content before introducing it into the game.) Here, I have been working on player modelling through preference learning, and on data mining on large sets of game data. I've also been looking at various methods of reproducing player behaviour through machine learning based on player data. In the past, I have worked on several topics in evolutionary computation, in particular a project to unify evolutionary methods in a geometric framework. I've also at various points published research on e.g. evolutionary robotics and modularity in neural networks, and maintain an interest in these topics. And before getting caught up in computational intelligence, I was interested in consciousness and the problem of other minds, but I guess I'm too impatient for philosophy.
