PDDL 2.1: Representation vs. Computation
arXiv:1110.2731 · doi:10.1613/jair.1995
Abstract
I comment on the PDDL 2.1 language and its use in the planning competition, focusing on the choices made for accommodating time and concurrency. I also discuss some methodological issues that have to do with the move toward more expressive planning languages and the balance needed in planning research between semantics and computation.
