  preprint withdrawn. A revised version of this paper, with different authors
appears in E. Nelson, P. Wolynes, and J. Onuchic, in Optimization in
computational chemistry and molecular biology, C. Floudas and P. Pardalos
editors, (1999)). The main failing of my approach in these papers is the fact
that the Hamiltonian and order parameters are based on pair distances only, and
therefore do not break the local gauge (reflection) symmetry. Consequently, the
order parameters cannot detect the difference between (for example) a partially
compact topology and its mirror image. I take full responsibility for this
problem, the withdrawal of this preprint, and the comments made above. Erik D.
