RESUMO

A method is presented for starting from a very-low-energy high-dimensional conformation and obtaining a low-energy three-dimensional structure by gradual contraction of the dimensionality. The contraction in dimensionality is achieved by use of Cayley-Menger determinants, of which a simplified form is derived here. Preliminary results are presented for a virtual-bond pentapeptide and for full-atom representations of several terminally blocked amino acids.
