Usage

g3_optim(
  model,
  params,
  use_parscale = TRUE,
  method = "BFGS",
  control = list(),
  print_status = FALSE,
  print_id = "",
  ...
)

Arguments

params	The parameter template for a g3_cpp classed model.
use_parscale	Should parscale be used g3_tmb_parscale(params), see optim
method	The optimisation method, see optim
control	List of control options for optim, see optim
print_status	Print step comments, does not suppress comments from optim call (see control$trace)
print_id	A character string appended to the print statements (useful for when running g3_optim in parallel)
