In this 2017 GDC session, Lunarch Studios' David Churchill describes the Hierarchical Portfolio Search AI system created for Prismata, and how it can be adapted to fit almost any genre of game, including search-heavy ones like strategy games.

It was a detailed dive into a fascinating technical challenge rich in takeaways for game devs, so if you missed seeing it live, take advantage of the fact that you can now watch it for free on the official GDC YouTube channel!
