A Panorama of Research on CI and AI in Games

What has general game playing got to do with player modelling? Is procedural content generation relevant for research in believable agents? Can interactive narrative teach us about AI-assisted game design? This tutorial attempts to explain how everything fits together within our research field. We divide the whole field of CI/AI in Games into ten different research areas, and then we try to explain how they influence each other. Perhaps more importantly, we try to explain how these areas could influence each other, but don't yet. In other words, we will be suggesting what we consider interesting topics for future research, as well as trying to give a coherent picture of the whole field. We will endeavour to make the tutorial accessible to both newcomers to CIG research and seasoned veterans, to the extent there are any in this young field of ours.

The presenters:

Julian Togelius is Associate Professor at the Center for Computer Games Research, IT University of Copenhagen, Denmark. He works on all aspects of computational intelligence and games and on selected topics in evolutionary computation and evolutionary reinforcement learning. His current main research directions involve search-based procedural content generation in games, game adaptation through player modelling, automatic game design, and fair and relevant benchmarking of game AI through competitions. He is a past chair of the IEEE CIS Technical Committee on Games, and an associate editor of IEEE Transactions on Computational Intelligence and Games. Togelius holds a BA from Lund University, an MSc from the University of Sussex, and a PhD from the University of Essex.

Introduction to Evolutionary Game Theory

Many biological, social and economic processes are naturally modeled as a system of interacting individuals. Game theory provides a natural framework for capturing behavior in such systems. In particular, game theory techniques have been widely used to study one of the great open questions in nature: how does cooperation grow in populations? This talk provides an introduction to evolutionary game theory, which combines the principles of evolution and classical game theory to see how cooperative behavior might evolve in populations. The talk begins with a brief introduction to classical game theory covering concepts such as payoff matrices, Nash equilibrium, and evolutionary stable strategies. Widely investigated games such as the iterated prisoner’s dilemma and the hawk-dove game will also be discussed. From there the fundamentals of evolutionary game theory are presented. Concepts such as frequency dependent fitness selection, evolution in finite populations via the Moran process, spatial games, and public goods games will be discussed. A survey of the recent work in this area is presented along with a critique on what has been accomplished and where future research efforts should concentrate.
