		MinimizerMap &	min_map,
		scoring::ScoreFunction const &	scorefxn,
		Multivec const &	vars,
		Multivec &	dE_dvars
	)

Detailed:

car note that this calculates the deriv for all torsion angles even car those that are fixed. Because of the way that the derivative is car calculated, I don't believe this is a significant slow down (ie car have to run over all the atom pairs twice, regardless of the number car of torsion angles)

car multiple neighborlists: car cendist centroid distances in current structure, cutoff for vdw car dis2_tether centroid distances in tether structure, cutoff for tether

db computes the derivative of E with respect to each db of the torsion angles. Using the chain rule, we have db db dE/d phi = dE/dr * dr/dphi db db dr/dphi = Eab x (V-Vb) . (V' - V)/|V-V'| db db (the first cross product is the displacement of V upon a rotation dphi db around the unit vector Eab, Vb is the coordinates of the second atom in db the bond) db car dE/dR = 2r (for vdw at least) db since | V-V'| = r, db db dE/ dphi = 2 Eab x (V-Vb) . (V' - V) db db note that Eab and Vb are different for each torsion angle, but V' db and V are the same. rearranging: db db = - 2 Eab X Vb . (V' - V) - 2 Eab . (V' x V). db db now we need the averages over all Vi of the difference and the db crossproduct of V and V'.

car below, Eab x Vb is 'vec' car Eab is 'unit' car (V'-V) is 'f2' car 'F2tot' = f2*dE_dR (cumulative) car (V' X V) is 'f1' ('F1_xxxE' is cumulative for potential xxx) car eval_dE_dR actually returns dE_dR/r

car if two atoms are fixed relatively in cartesian space, then dr/dphi = 0 car and there is no contribution to the derivative
