Results from the application of the GA to other molecules suggest that it can reliably find very good or globally optimal conformations for molecules having less than thirty rotatable bonds. When applied to larger molecules, the GA can still find good conformations. Second, several programs are presented that were designed to evaluate various modes of the packing of several molecules into a cluster. The first program is a useful means of evaluating how well a given molecule can pack in one specific mode of assembly, while the second one can search to find the energy of a group of molecules in their preferred arrangement.

This simulation can give a useful indication of how successful a proposed system might be, or in assessing the degree of reaction in known systems required to account for experimental observations.
