AI Summit: Logic Programming in Commercial Games: Experiences and Lessons Learned

Robert Zubek  (Founder & CTO, SomaSim LLC)

Ian Horswill  (Associate Professor, Computer Science, Northwestern University)

Location: Room 2002, West Hall

Date: Monday, March 20

Time: 3:00 pm - 3:30 pm

Pass Type: All Access Pass, Summits Pass, Independent Games Summit Pass

Topic: Programming

Format: Lecture

Vault Recording: Video

Audience Level: Intermediate

In this session, Robert Zubek and Ian Horswill describe their experiences using Logic Programming in the development of two recent games.

Logic Programming is a paradigm where the programmer specifies the "what" but not the "how," by defining rules and goals, but leaving it to the system to figure out execution details. It's a powerful approach for use in games, and this talk describes how they used LP for three different purposes: NPC AI that encoded social norms, PCG code using constraint satisfaction, and build-time tools that verified asset consistency.

The talk ends with pointers for attendees to get start using LP in their own projects.

Takeaway

Attendees will come away with knowledge of how and why they might want to integrate Logic Programming into their games, what kinds of benefits and drawbacks might be expected, and pointers to open source implementations that they can start using immediately.

Intended Audience

This is for intermediate-to-advanced programmers, and advanced-level designers. Programming experience is not necessary to benefit from this talk.
