Setting NL Options
Sets and changes the NLOPT options.
nl.opts(optlist = NULL)
optlist |
list of options, see below. |
The following options can be set (here with default values):
stopval = -Inf, # stop minimization at this valuextol_rel =
1e-6, # stop on small optimization stepmaxeval = 1000, # stop on
this many function evaluationsftol_rel = 0.0, # stop on change
times function valueftol_abs = 0.0, # stop on small change of
function valuecheck_derivatives = FALSE
returns a list with default and changed options.
There are more options that can be set for solvers in NLOPT. These
cannot be set through their wrapper functions. To see the full list of
options and algorithms, type nloptr.print.options().
