HPstruct implements the CPSP approach, as introduced by Backofen and Will (Constraints, 2006), to predict provably optimal structures of 3D lattice proteins in the HP-model. For a given HP-sequence S and a given lattice type (cubic or face centered cubic), (all) optimal structures are calculated. The CPSP approach computes the global minimal energy for S, too.
