PDDL2.2: The Language for the Classical Part of the 4th International Planning Competition

This document defines the language to be used in the classical part of the 4th International Planning Competition, IPC-4. The language comprises all of PDDL2.1 levels 1, 2, and 3, as defined by Maria Fox and Derek Long in [Fox & Long 03]; parts of this document have been copied from that source. On top of this language, for IPC-4 derived predicates are re-introduced, and timed initial literals are (newly) introduced into the competition language. We give the syntax and semantics of these constructs.
