Hierarchical Planning

An ICAPS 2018 Workshop
Delft, The Netherlands
June 25 or June 26, 2018

Call for the First International Workshop on Hierarchical Planning

The motivation for using hierarchical planning formalisms is manifold. It ranges from an explicit and predefined guidance of the plan generation process and the ability to represent complex problem solving and behavior patterns to the option of having different abstraction layers when communicating with a human user or when planning co-operatively.

The best-known formalism in the field is Hierarchical Task Network (HTN) planning. In addition, there are several other hierarchical planning formalisms, e.g., hybrid planning (incorporating aspects from POCL planning), Hierarchical Goal Network (HGN) planning (incorporating a hierarchy on goals), or formalisms that combine task hierarchies with timeline planning (e.g. ANML). We encourage contributions independent of the underlying hierarchical planning formalism.

Hierarchies induce fundamental differences from classical planning, creating distinct computational properties and requiring separate algorithms for plan generation, plan verification, plan repair, and practical applications. Many of these aspects of hierarchical planning are still unexplored. The workshop invites submissions on any aspects of hierarchical planning. Topics of interests include but are not limited to:

  • theoretical foundations, e.g., complexity results
  • heuristics, search, and other solving techniques for plan generation
  • techniques and foundations for providing modeling support
  • challenges and lessons learned from creating hierarchical planning models
  • applications of hierarchical planning (e.g., challenges and lessons learned from applying hierarchical planning techniques in real-world systems)
  • aspects of engineering hierarchical planning systems
  • plan explanation based on hierarchical models
  • hierarchical plan repair techniques
  • techniques for verifying solutions of hierarchical planning problems

Submission Details

The formatting guidelines (author kit, etc.) are the same as at ICAPS 2018. Authors may submit *long papers* (8 pages plus up to one page of references) or *short papers* (4 pages plus up to one page of references). In case of acceptance, the full 5, resp. 9, pages can be used for the paper, e.g. to address the reviewers' comments.

Like at the main conference, there will be a high quality double-blind review process against the standard ICAPS criteria of relevance, originality, significance, clarity, and soundness. However, submissions may be less evolved than at the main conference.
