ddd_optimizer: Optimizer functions from package DDD

In TheoPannetier/comrad: R implementation of a Competitive Radiation model

Optimizer functions from package DDD

Description

See DDD::optimizer() documentation. I have frozen argument optimmethod to subplex, and added an early exit if the first subplex cycle evaluates to -Inf.

Usage

ddd_optimizer(
  optimpars = c(1e-04, 1e-04, 1e-06, 1000),
  num_cycles = 1,
  fun,
  trparsopt,
  ...
)

Arguments

optimpars	Parameters of the optimization: relative tolerance in function arguments, relative tolerance in function value, absolute tolerance in function arguments, and maximum number of iterations
num_cycles	Number of cycles of the optimization. When set to Inf, the optimization will be repeated until the result is, within the tolerance, equal to the starting values, with a maximum of 10 cycles.
fun	Function to be optimized
trparsopt	Initial guess of the parameters to be optimized
...	Any other arguments of the function to be optimimzed, or settings of the optimization routine

Value

out	A list containing optimal function arguments (par, the optimal function value (fvalues) and whether the optimization converged (conv)
