Webb18 maj 2007 · We now discuss two different schemes for increasing or decreasing the dimension by 1. In the first, which is the more complex, two units are selected and replaced by three and the reverse of this and labelled moves 2–3 in Appendix B. The second scheme involves replacing one unit by two units and the reverse of this. WebbAug 2004 - Jun 20116 years 11 months. Boston MA.

We have developed a formulation for molecular dynamics algorithm for the replica-exchange method. The effectiveness of the method for the protein-folding problem is tested with the penta-peptide Met-enkephalin. The method can overcome the multiple-minima problem by exchanging non-interacting replicas of the …
