AI Summit: Advanced Real-Time Hierarchical Task Networks: A New Approach


HTN systems are an AI architecture for long-term behavior in games. However, the HTN systems have no mechanism to handle accidental changes or hostile agent behavior. When using the HTN systems in games where the situation changes in real time, conventional games have dealt with this by increasing the frequency of "replanning," which is the process of remaking the plan. In many cases, this resulted in destroying the long-term thinking of the AI. For this reason, we have developed ART-HTN, an evolution of the HTN system that is more suitable for real-time games. In this session, we will talk about how to deal with the problems of HTN systems and how to adapt it to various situations.
