This function creates an object of reference-class CTRL
which
contains optimization parameters, e.g. the maximum number of
iterations.
ctrl(maxiters = 100L, abstol = 1e-06, reltol = 1e-06,
feastol = 1e-06, stepadj = 0.95, beta = 0.5, trace = TRUE)
An object of reference-class CTRL
.
integer
, the maximum count of iterations.
numeric
, the absolute level for convergence to be
achieved.
numeric
, the relative level for convergence to be
achieved.
numeric
, the feasable level for convergence to be
achieved.
numeric
, step size adjustment in combined step.
numeric
, parameter in backtracking line search.
logical
, if TRUE
(the default), the
solver's progress during the iterations is shown.
