Newswise — The main challenge at hand is to make computer-generated characters--dubbed bots--act realistically. They should be able to engage in believable conversations, plan their actions, find their way around virtual worlds, and learn from their mistakes. That is, they need to be smart.

Today, many video games create just an illusion of intelligence using a few easy programming tricks. But in the not-so-distant future, game bots will routinely use sophisticated AI techniques, such as machine learning, to shape their behavior. This is important even if you're not a gamer because the work being done to make video games feel more realistic should carry AI researchers a long way toward their ultimate goal of developing general-purpose machine intelligence.
