| dc.description | Crystal lattices are infinite periodic graphs that occur naturally in a variety of geometries and which are of fundamental importance in polymer science. Discrete models of protein folding use crystal lattices to define the space of protein conformations. Because various crystal lattices provide discretizations of the same physical phenomenon, it is reasonable to expect that there will exist "invariants" across lattices related to fundamental properties of the protein folding process. This paper considers whether performance-guaranteed approximability is such an invariant for HP lattice models. We define a master approximation algorithm that has provable performance guarantees provided that a specific sublattice exists within a given lattice. We describe a broad class of crystal lattices that are approximable, which further suggests that approximability is a general property of HP lattice models. 1 C.S.Calude and G.Stefanescu (eds.).
