 DESCRIPTION
Run energy minimization using a method of choice (steepest descent of conjugate gradient). After minimization is done, the dynamical matrix is computed and diagonalized and the normal frequencies are listed along with eigenvectors. The following subcommands may be specified within MINIMIZE:

CG, SD, WRITE_GRADIENT, AGBNP

$\bullet$	GC    eps_energy    Use conjugate gradient with energy tolerance eps_energy.
$\bullet$	SD    eps_energy    Use steepest descent with energy tolerance eps_energy.
$\bullet$	WRITE_GRADIENT Write final gradient at each atom.
$\bullet$	AGBNP Minimization is done using an AGBNP model[162] for implicit solvent. A file named agbnp.param file must be in the current directory. Dielectric constant of the solvent continuum is set in that file. In the present release AGBNP works only for constant volume minimization and with no &SOLVENT specification.
