Summary of paper
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.
Some key terms
some scenarios
- when we have soft constraints and goals, it can be useful to give different priorities to them.
