Abstract:Recently, inferred effects of compound (totally ordered) HTN planning tasks were introduced. Guaranteed effects are those which hold true after all executable refinements of such a task, whereas possible effects are only required to hold after some of them.

We show that the problem turns NP-complete for conjunctive… Show more
