TorchLight

Participant : Jörg Hoffmann [correspondant] .

TorchLight is a system for auomatic domain analysis in planning. It automatically infers properties of the search space surface under a partcular heuristic function, called $h^{+}$, that underlies most current state of the art planning systems (including FF). TorchLight examines certain structural properties of the PDDL input, and exploits a number of connections between this structure and the search space surface under $h^{+}$. For example, one of its outputs provides an estimate of the fraction of states that lie on local minima.
