FLECS: Planning with a Flexible Commitment Strategy.

Journal of Artificial Intelligence Research, 3:25–52,

Available from journal's web page.
There has been evidence that least-commitment planners can efficiently handle planning problems that involve difficult goal interactions. This evidence has led to the common belief that delayed-commitment is the "best" possible planning strategy. However, we recently found evidence that eager-commitment planners can handle a variety of planning problems more efficiently, in particular those with difficult operator choices. Resigned to the futility of trying to find a universally successful planning strategy, we devised a planner that can be used to study which domains and problems are best for which planning strategies. In this article we introduce this new planning algorithm, FLECS, which uses a FLExible Commitment Strategy with respect to plan-step orderings. It is able to use any strategy from delayed-commitment to eager-commitment. The combination of delayed and eager operator-ordering commitments allows FLECS to take advantage of the benefits of explicitly using a simulated execution state and reasoning about planning constraints. FLECS can vary its commitment strategy across different problems and domains, and also during the course of a single planning problem. FLECS represents a novel contribution to planning in that it explicitly provides the choice of which commitment strategy to use while planning. FLECS provides a framework to investigate the mapping from planning domains and problems to efficient planning strategies.

There has been evidence that least-commitment
planners can efficiently handle planning problems
that involve difficult goal interactions. This
evidence has led to the common belief that
delayed-commitment is the "best" possible planning
strategy. However, we recently found evidence that
eager-commitment planners can handle a variety of
planning problems more efficiently, in particular
those with difficult operator choices. Resigned to
the futility of trying to find a universally
successful planning strategy, we devised a planner
that can be used to study which domains and problems
are best for which planning strategies. In this
article we introduce this new planning algorithm,
FLECS, which uses a FLExible Commitment Strategy
with respect to plan-step orderings. It is able to
use any strategy from delayed-commitment to
eager-commitment. The combination of delayed and
eager operator-ordering commitments allows FLECS to
take advantage of the benefits of explicitly using a
simulated execution state and reasoning about
planning constraints. FLECS can vary its commitment
strategy across different problems and domains, and
also during the course of a single planning
problem. FLECS represents a novel contribution to
planning in that it explicitly provides the choice
of which commitment strategy to use while
planning. FLECS provides a framework to investigate
the mapping from planning domains and problems to
efficient planning strategies.
