Some sort of biassed sampling will certainly help. Just be aware that
what you want to do is at the cutting edge of simulation research.
This is not something for which you just need to find the proper input
variables; it is more like a major portion of a Ph.D. project. You almost
certainly want to gain experience with simpler problems first, and with
the literature, before tackling something as buried as the GFP binding
pocket.
