Automated design for playability in computer game agents

This paper explores whether a novel approach to the creation of agent controllers has potential to overcome some of the drawbacks that have prevented novel controller architectures from being widely implemented. This is done by using an evolutionary algorithm to generate finite state machine controllers for agents in a simple role playing game. The concept of minimally playable games is introduced to serve as the basis of a method of evaluating the fitness of a game´s agent controllers.
