CIG 2008 special session on coevolution in games

Coevolution in Games: A Special Session at IEEE Symposium on Computational Intelligence and Games
Perth, Australia
15-18 December, 2008

Special Session Chairs: Julian Togelius, Alan Blair and Philip

Submission deadline: 15 August 2008


In coevolution, the fitness of a solution is determined not (only) by a fixed fitness function, but also by the other solution(s) being evaluated. Thus, coevolution has the potential to overcome several problems with static fitness functions, paving the way for more open-ended evolution. However, several phenomena common to coevolutionary algorithms are at present poorly understood, including cycling and loss of gradient. Further understanding of such phenomena would facilitate more widespread use of coevolutionary algorithms.

This special session seeks to bring together research that uses coevolutionary algorithms to learn to play games, uses games to investigate coevolution, or uses coevolution as a basis for game design. Due to their adversarial nature, often involving interaction of multiple agents, games are uniquely suited to be combined with
coevolution. We invite both theoretical and applied work in the intersection of coevolution and games, including but not limited to the following topics:

Competitive coevolution
Cooperative coevolution
Multiple populations in coevolution
Coevolution with diverse representations
Theory of coevolution
Preventing cycling and loss of gradient
Coevolution-based game design
Self-play and coevolutionary-like reinforcement learning
Relative versus absolute fitness metrics

About the organisers:

Julian Togelius is a researcher at the Dalle Molle Institute for Artificial Intelligence (IDSIA) in Lugano, Switzerland. His research interests include evolving game-playing agents, modelling player behaviour, and evolving interesting game content, mainly using evolutionary and coevolutionary techniques. He also co-organizes the well-attended Simulated Car Racing Competitions for the IEEE CIG and CEC conferences. See his home page for more information.

Philip Hingston is an associate professor of computer science at Edith Cowan University in Perth. His research interests are in the theory and application of artificial intelligence and computational intelligence. He has a particular interest in evolutionary computation as a tool for design, and in computer games. He is chair of the IEEE CIS Task Force on co-evolution. More information can be found on his home page.

Alan Blair is Chair of the IEEE CIS Task Force on Co-evolution and Games. His research interests include robot navigation, image and language processing as well as co-evolutionary learning for Backgammon, Tron, IPD, simulated hockey and language games. Homepage.
