Polak-Ribiere conjugate-gradient minimization

Inc., 2000, USA. The geometry optimizations used a Polak-Ribiere conjugated gradient algorithm for energy minimization in vacuum or water, with a final gradient of 0.1 kcal/A mol. The periodic box of water molecules comprises 216 water molecules in all calculations... [Pg.44]

In the Refinement step, the accepted test configurations generated from the previous Site-Search step wiU be minimized using the Polak-Ribiere non-Unear conjugate gradient algorithm (Press etal., 1988) with equation 1 (Hellinga Richards, 1991). [Pg.131]
