1CS 188: Artificial IntelligenceFall 2010Lecture 26: Conclusion12/2/2010Dan Klein – UC BerkeleyPacman Contest Challenges: Long term strategy Multiple agents Adversarial utilities Uncertainty about other agents’ positions, plans, etc.2Pacman Contest 50 teams Creative names: ConditionalIndependenceDay, NoPlaceLike127001, … Creative methods: tracking, learning, search… 50 qualifiers (a third of the class!) XYZ achievements Amazing work by everyone! Final Tournament … Final matches: now!3Finalists4For Third Place5For First / Second Place62…and Congratulations to All! Amazing work by everyone Record number of entries (60 teams) Record number of qualifications (45!) Lots of mutual support on newsgroup / office hours… You should all be proud of what you’ve accomplished!7Example: Starcraft8What is Starcraft?9Image from Ben WeberWhy is Starcraft Hard? Starcraft is: Adversarial Long Horizon Partially Observable Realtime Concurrent … No single algorithm (e.g. minimax) will solve it off-the-shelf10The Berkeley Overmind11Search: path planningMinimax: targetingLearning: micro controlInference: tracking unitsScheduling: resource managementHierarchical controlhttp://overmind.eecs.berkeley.eduSearch for Pathing12[Pathing]3Minimax for Targeting13[Targeting]RL for Micro Control14[RL, Potential Fields]Inference / VPI / Scouting15[Scouting, Cloaking]AIIDE 2010 Competition16Pacman: Beyond Simulation?Students at Colorado University: http://pacman.elstonj.com[DEMO]Bugman?

Congratulations, you’ve seen the basics of modern AI … and done some amazing work putting it to use! How to continue: Machine learning: cs281a / cs281b Cognitive modeling: cog sci 131 Vision: cs280 Robotics: cs287 NLP: cs288 Decision making: cs289 … and more; ask if you’re interested Next term: cs194 (Starcraft, not yet in telebears) cs288 (focus on MT for SP11) maybe one other grad class TBA (cs289?)19That’s It!
