optimizer 1.1.2

  • New ParameterSpaces R6 object to transform parameters between optimization and interpretation space.

optimizerR 1.1.1

  • The Objective object now allows for different types of output structures of the objective function, for which a template can be provided via the $output_template field.

optimizerR 1.1.0

  • The Optimizer object has a new method optimize which can be used for minimization and maximization by setting the argument direction.

  • In method Objective$initialize(), renamed argument objective -> f.

  • In method Objective$initialize(), if target = NULL (the new default), the first argument from f is taken as target argument.

optimizeR 1.0.5

  • Removed install_optimizer_packages().

optimizeR 1.0.4

  • Fixed bug and added test cases when having fixed arguments that are NULL.

optimizeR 1.0.3

  • Fixed bug in creating error message in case of a time out.

  • Added checks for objective, initial, and ellipsis argument for the optimizer function.

  • Added verbose argument to methods $get_argument() and $remove_argument() of Objective object.

  • Added field fixed_arguments to Objective object which returns the names of the fixed arguments.

  • Fixed bug in proper backwards compatibility.

optimizeR 1.0.2

  • Small bug fixes.

  • Backward compatibility with {optimizeR} version 0.3.3.

optimizeR 1.0.1

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

optimizeR 1.0.0

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

optimizeR 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).

optimizeR 0.3.2

optimizeR 0.3.1

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

optimizeR 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().

optimizeR 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.

optimizeR 0.1.0

  • Initial CRAN release.
