Motivation

  • the notion of plan quality in automated planning is a practically very important issue.
  • it is important to generate plans of good or optimal quality and we need to express the plan quality
  • the proposed extended language allows us to express strong and soft constraints on plan trajectories
    • i.e., constraints over possible actions in the plan and intermediate states reached by the plan
  • as well as strong and soft problem goals.

  • when we have soft constraints and goals, it can be useful to give different priorities to them.
