title: 'optextras: Tools to Support Optimization Possibly with Bounds and Masks'
version: 2019-12.4
doi: 10.32614/CRAN.package.optextras
abstract: Tools to assist in safely applying user generated objective and derivative
  function to optimization programs. These are primarily function minimization methods
  with at most bounds and masks on the parameters. Provides a way to check the basic
  computation of objective functions that the user provides, along with proposed gradient
  and Hessian functions, as well as to wrap such functions to avoid failures when
  inadmissible parameters are provided. Check bounds and masks. Check scaling or optimality
  conditions. Perform an axial search to seek lower points on the objective function
  surface. Includes forward, central and backward gradient approximation codes.
