optimize selects the method for propagating the atomic positions. Currently, the accepted options are:
"vv"for Velocity Verlet molecular dynamics (this is the default if you don't choose anything)"gd"for gradient descent energy minimization

Example
optimize = "gd" ! Do gradient descent minimization in this case e_tol = 1.e-6 ! Energy threshold for convergence md_nsteps = 1000 ! Maximum number of iterations (it will break earlier if convergence to e_tol is reached) max_opt_step = 0.1 ! Angstrom
