International Planning Competition (IPC-4)

The Fourth International Planning Competition will be held in conjunction with the International Conference on Automated Planning and Scheduling. The competition provides a forum for researchers to compare planning techniques and systems in a friendly head-to-head competition.

Classical Planning Competition

The classical part of the competition continues the tradition of a biannual public challenge on deterministic planning benchmark domains. This year, there will be two minor language extensions to the domain definitions: "derived predicates" and "timed initial literals", added on top of the PDDL2.1 language used at IPC-3. The web page at https://ipc04.icaps-conference.org has all information on IPC-4. It includes a download of a document that gives the syntax and semantics of the input planning description language PDDL2.2 and downloads of testing examples for the new language features.

Deadline for registration is January 27, 2004. However, the sooner we know how many systems will participate, and what language classes they will be able to handle, the better it will be for the organization of the competition. (The data collection phase is in between February and April 2004.) Iterested researchers should contact the organizers by sending mail to stefan.edelkamp@cs.uni-dortmund.de or hoffmann@informatik.uni-freiburg.de

Probabilistic Planning Competition

The First International Probabilistic Planning Competition will be held in conjunction with the 2004 International Conference on Automated Planning and Scheduling (ICAPS-04). The competition is being organized as a parallel track of the Fourth International Planning Competition (IPC) at ICAPS-04.

Previous IPCs have focused exclusively on classical planning---sequential decision making when the effects of all decisions are deterministic. Over the past decade, as computers have become more and more integrated with the physical world, researchers have begun to study models that can represent the inherent uncertainty present in the effects of many decisions. In this setting, plans are evaluated by how likely they are to achieve desired outcomes.

The challenge tasks for the competition will be expressed in a new probabilistic extension of PDDL. This domain description language provides for an object-based format for compactly expressing Markov decision processes (MDPs), the prevailing model for defining decision-theoretic planning problems. The competition will also include a non-deterministic demonstration track for researchers interested in showcasing their planners that address problems with non-probabilistic uncertainty.
