Generate control specifications for f function

control_f(
  numer_grad = TRUE,
  improve_hessian = TRUE,
  eps = 1e-04,
  use_same_V = FALSE
)

Arguments

numer_grad

whether to use numerical gradient

improve_hessian

improve numerical hessian by using central difference estimation (O(eps^2) error) default is forward difference estimation (O(eps) error)

eps

eps for computing numerical gradient

use_same_V

use the same V for preconditioning in the same chain

Value

list of control variables
