Accurately determining intermediate and terminal plan states using bayesian goal recognition
David Pattison,Derek Long +1 more
TL;DR: IGRAPH is discussed, which improves upon its predecessor by utilising Bayesian inference to determine both terminal and intermediate goals/states which the agent being observed is likely to pass through.
Proceedings Article
Boosting search guidance in problems with semantic attachments
TL;DR: Guided by both causal and numeric information, the planner is able to exploit an approximation of the numeric information calculated by the advisor to compute informative heuristic estimators and outperforms traditional approaches, especially against problems with numeric goals.
Friends or Foes? An AI Planning Perspective on Abstraction and Search
Jörg Hoffmann,Ashish Sabharwal,Carmel Domshlak,Derek Long,Stephen F. Smith,Daniel Borrajo,Lee McCluskey +6 more
TL;DR: It is proved that all abstraction (over-approximation) methods known in planning cannot improve the best-case behavior of informed search, and this result is potentially relevant also for model checking, where SAT-based techniques have recently been combined with abstraction.
