Landmarks for Numeric Planning Problems

Scala, Enrico; Haslum, Patrik; Magazzeni, Daniele; Thiebaux, Sylvie


The paper generalises the notion of landmarks for reasoning about planning problems involving propositional and numeric variables. Intuitively, numeric landmarks are regions in the metric space defined by the problem whose crossing is necessary for its resolution. The paper proposes a relaxationbased method for their automated extraction directly from the problem structure, and shows how to exploit them to infer what we call disjunctive and additive hybrid action landmarks.
