## Keyword descriptions

ANNEALING: real = 1.00000000E+000

  Specify the annealing coefficient [Edit on GitHub]

PROJ_VELOCITY_VERLET: logical = T

  Lone keyword: `T`

  Usage: PROJ_VELOCITY_VERLET <LOGICAL>

  Uses a Projected Velocity Verlet instead of a normal Velocity Verlet. Every time the cosine between velocities and forces is < 0 velocities are zeroed. [Edit on GitHub]

SD_LIKE: logical = F

  Lone keyword: `T`

  Usage: SD_LIKE <LOGICAL>

  Zeros velocity at each MD step emulating a steepest descent like (SD_LIKE) approach [Edit on GitHub]
