Preface

The computer game industry has become a multibillion-dollar commercial enterprise, comparable in size and scope to the film industry. Game system requirements are an important driver of hardware and soware innovation in the computer industry, and games have expanded to fill market niches opened by new platforms such as mobile phones, consoles, tablets, and social media. Artificial intelligence is a major component contributing to this success, creating the conditions for more complex virtual environments, realistic non-player characters, and engaging experiences.
