abstract = {Domain control knowledge (DCK) has proven effective in improving
the efficiency of plan generation by reducing the search space
for a plan. Procedural DCK is a compelling type of DCK that
supports a natural specification of the skeleton of a plan.
Unfortunately, most state-of-the-art planners do not have the
machinery necessary to exploit procedural DCK. To resolve this
deficiency, we propose to compile procedural DCK directly into
PDDL2.1, thus enabling any PDDL2.1-compatible planner to exploit
it. The contribution of this paper is threefold. First, we
propose a PDDL-based semantics for an Algol-like, procedural
language that can be used to specify DCK in planning. Second, we
provide a polynomial algorithm that translates an ADL planning
instance and a DCK program, into an equivalent, program-free
PDDL2.1 instance whose plans are only those that adhere to the
program. Third, we argue that the resulting planning instance is
well-suited to being solved by domain-independent heuristic
planners. To this end, we propose three approaches to computing
domain-independent heuristics for our translated instances,
sometimes leveraging properties of our translation to guide
search. In our experiments on familiar PDDL planning benchmarks
we show that the proposed compilation of procedural DCK can
significantly speed up the performance of a heuristic search
planner. Our translators are implemented and available on the
web.
