Returns a generator of jobs for a full optimization run. Basically,
this runs an infinite series of geometry optimization jobs until the

Args:
vasp_cmd (str): Command to run vasp as a list of args. For example,
if you are using mpirun, it can be something like
["mpirun", "pvasp.5.2.11"]
auto_npar (bool): Whether to automatically tune NPAR to be sqrt(
number of cores) as recommended by VASP for DFT calculations.
Generally, this results in significant speedups. Defaults to
True. Set to False for HF, GW and RPA calculations.
vol_change_tol (float): The tolerance at which to stop a run.
Defaults to 0.05, i.e., 5%.
max_steps (int): The maximum number of runs. Defaults to 10 (
highly unlikely that this limit is ever reached).

**vasp_job_kwargs):
"""
Returns a generator of jobs for a constrained optimization run. Typical
use case is when you want to approximate a biaxial strain situation,
e.g., you apply a defined strain to a and b directions of the lattice,
but allows the c-direction to relax.
Some guidelines on the use of this method:
i. It is recommended you do not use the Auto kpoint generation. The
grid generated via Auto may fluctuate with changes in lattice
param, resulting in numerical noise.
ii. Make sure your EDIFF/EDIFFG is properly set in your INCAR. The
optimization relies on these values to determine convergence.
Args:
vasp_cmd (str): Command to run vasp as a list of args. For example,
if you are using mpirun, it can be something like
["mpirun", "pvasp.5.2.11"]
lattice_direction (str): Which direction to relax. Valid values are
"a", "b" or "c".
initial_strain (float): An initial strain to be applied to the
lattice_direction. This can usually be estimated as the
negative of the strain applied in the other two directions.
E.g., if you apply a tensile strain of 0.05 to the a and b
directions, you can use -0.05 as a reasonable first guess for
initial strain.
atom_relax (bool): Whether to relax atomic positions.
max_steps (int): The maximum number of runs. Defaults to 20 (
highly unlikely that this limit is ever reached).
algo (str): Algorithm to use to find minimum. Default is "bfgs",
which is fast, but can be sensitive to numerical noise
in energy calculations. The alternative is "bisection",
which is more robust but can be a bit slow. The code does fall
back on the bisection when bfgs gives a non-sensical result,
e.g., negative lattice params.
\*\*vasp_job_kwargs: Passthrough kwargs to VaspJob. See
:class:`custodian.vasp.jobs.VaspJob`.
Returns:
Generator of jobs. At the end of the run, an "EOS.txt" is written
which provides a quick look at the E vs lattice parameter.

Initializes a NEBAnalysis object from a directory of a NEB run.
Note that OUTCARs must be present in all image directories. For the
terminal OUTCARs from relaxation calculations, you can specify the
locations using relaxation_dir. If these are not specified, the code
will attempt to look for the OUTCARs in 00 and 0n directories,
followed by subdirs "start", "end" or "initial", "final" in the
root_dir. These are just some typical conventions used
preferentially in Shyue Ping's MAVRL research group. For the
non-terminal points, the CONTCAR is read to obtain structures. For
terminal points, the POSCAR is used. The image directories are
assumed to be the only directories that can be resolved to integers.
E.g., "00", "01", "02", "03", "04", "05", "06". The minimum
sub-directory structure that can be parsed is of the following form (
a 5-image example is shown):
00:
- POSCAR
- OUTCAR
01, 02, 03, 04, 05:
- CONTCAR
- OUTCAR
06:
