[gmx-users] global or local minimum

[KS Rotondi]

This question came up a few weeks ago.

The simple answer is, you can be pretty sure you're at the bottom of  
some potential energy surface but you can't know if you're at a local  
or global minimum.

However, if you are using an experimentally determined protein  
structure, and the structure is reflective of the natural state of the  
protein, and you believe the Nobel Prize winning work of Dr. Christian  
Anfinsen, you can be pretty sure you are looking at the global minimum.
