Call for Contributions
WORKSHOP ON PDDL
to be held in conjunction with ICAPS 2003
The International Conference on Automated Planning & Scheduling
Trento, Italy, 10 June 2003
http://csl.anu.edu.au/~thiebaux/workshops/ICAPS03
PDDL has become a de facto standard language for describing planning
domains, not only for the planning 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:
* Assessment of PDDL and comparison with other modelling languages:
- adequacy and impact as a domain definition language for planning
- adequacy and impact as a planning competition language
- missing features and limiting assumptions
- alternative planning domain modelling languages
- general purpose vs special purpose modelling languages --
embedding of special purpose features into a general purpose language
- assessment of and investigations into PDDL+
* Proposals for extensions of PDDL, for instance:
- to partially observable, non-deterministic, probabilistic domains
- to multi-criteria optimisation
- to multi-agent domains
- to hierarchical planning
- web-PDDL, ontologies
- PDDL for robot planning
- extensions to the definition of a plan - contingencies,
iteration, sensing actions and other execution-level features
* Discussion of the infrastructure supporting PDDL:
- what is the ambition for PDDL: a competition standard,
a community standard, a research standard or an industry standard?
- are we ready to adopt such a standard?
- should there be a formal standards committee?
- should developments be allowed to branch as expressive power increases?
- what tools are required to support wide adoption of PDDL?
-----------------------------------------------------------------
Submission guidelines
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.
* Position papers
describing the authors' opinion about some of the workshop
issues. These will be refereed by the workshop committee, with
the aim of gathering papers and participants with conflicting
opinions for panel discussions.
* Challenge papers
describing a planning domain of interest or some feature of a
domain, identifying contender modelling languages, and asking how
best to model this domain or domain feature. The program
committee will select a number of challenge papers and organise
for a group of participants to take on the challenges and present
the results at the workshop. Authors of challenge papers should
be prepared to contribute to challenges offered by others.
* Technical papers
which will be reviewed as such by the program committee (for
instance on an extension of PDDL, a new modelling language, a
survey of existing modelling languages and comparison of their
expressive power, a study of the impact of PDDL on planning
competition results, etc).
* Short statements of interest (these will not appear in the proceedings).
Forward electronic submissions (10 pages max. AAAI style)
in postscript or PDF format to Sylvie.Thiebaux@anu.edu.au
