version 1.0.1

• Fixed wrong values for "out_value" and "out_parameter" in the optimizer dictionary entry for stats::optim.

verion 1.0.0

• Instead of using S3 classes, we treat optimizers as R6 objects now.

version 0.3.3

• Removed package start-up message.

• Added the .direction argument to define_optimizer() to specify whether the optimizer minimizes or maximizes.

• Added a dot before the argument names for define_optimizer() to avoid clashes with the ... argument.

• Removed dependency on {glue}.

• Using TestFunctions::TF_ackley instead of own implementation of Ackley function (for the validation).

version 0.3.2

• Just added package logo and created package website (https://loelschlaeger.de/optimizeR) with the {pkgdown} package. No code changes.

version 0.3.1

• In define_optimizer(), now validate = FALSE by default.

version 0.3.0

• Function set_optimizer() was renamed to define_optimizer().

• Inputs for define_optimizer() were renamed for clarity:

  • opt_fun -> optimizer
  • f -> objective
  • p -> initial
  • v -> value
  • z -> parameter
  • out_ign -> output_ignore
  • test_par -> validation_settings

• Elements for input validation_settings have been simplified, please see the documentation of define_optimizer().

• Elements in the output of apply_optimizer() were renamed for clarity:

  • v -> value
  • z -> parameter
  • time -> seconds (now just a numeric)

• Element initial (the starting parameter vector) was added to the output of apply_optimizer().

version 0.2.0

• Some functions were renamed:

  • optimizeR() -> apply_optimizer()
  • set_optimizer_nlm() -> optimizer_nlm()
  • set_optimizer_optim() -> optimizer_optim()

• Functions is_number(), try_silent(), timed(), and do.call_timed() are no longer exported.

• Function try_silent_timed() was removed.

version 0.1.0

• Initial CRAN release.
