Workshop on PDDL
Trento, Italy, June 10, 2003
PDDL was originally developed by Drew McDermott and the 1998 planning competition committee. It was inspired by the need to encourage the empirical comparison of planning systems and the exchange of planning benchmarks within the community. Its development improved the communication of research results and triggered an explosion in performance, expressivity and robustness of planning systems.
PDDL has now been used in all 3 planning competitions, undergoing various revisions for each. In the most recent competition PDDL was extended by Maria Fox, Derek Long and the 2002 committee to handle time and duration (PDDL2.1). Further enrichments to the modelling of hybrid and real-time systems (PDDL+) were proposed, while another committee is currently investigating extensions to probabilistic planning.
PDDL has become a de facto standard language for describing planning domains, not only for the competition but more widely, as it offers an opportunity to carry out empirical evaluation of planning systems on a growing collection of generally adopted standard benchmark domains. The emergence of a language standard will have an impact on the entire field, influencing what is seen as central and what peripheral in the development of planning systems. The adoption of PDDL in this role is itself an issue for debate: perhaps a completely different modelling language is called for. We believe that it is therefore important to provide a forum in which the community can give feedback and present their ideas to the language designers, and in which the language designers can discuss their ideas for maintaining and extending, or even replacing the language. Enabling this discussion and debate is the objective of this one day workshop, while setting the stage for an ongoing discussion of the future development of PDDL and the standardisation process.
Issues of interest include, but are not limited to:
Technical amendments to PDDL in its competition role should be directed to the complementary workshop on the International Planning Competition and its future.
Our objective for the workshop is to produce a forum for discussion, rather than to focus on a sequence of formal presentations. We actively encourage short submissions indicating polemical positions or challenges.
Researchers wishing to participate may submit either of the following.
Forward electronic submissions in postscript or PDF format to Sylvie Thiébaux. All submissions should be in AAAI conference format (see AAAI macros and templates), and should not exceed 10 pages.
