  • Removed Param objects. ParamSet now uses a data.table internally; individual parameters are more like Domain objects now. ParamSets should be constructed using the ps() shorthand and Domain objects. This entails the following major changes:
    • ParamSet now supports extra_trafo natively; it behaves like .extra_trafo of the ps() call.
    • ParamSet has $constraint
    • ParamSet objects are now less mutable. The only properties that can be changed are values, tags, deps, constraint and extra_trafo.
    • ParamSet$is_bounded is a vector with an entry for each parameter. Use $all_bounded for the previous behavior.
    • Condition objects are now S3 objects and can be constructed with CondEqual() and CondAnyOf(), instead of CondXyz$new(). (It is recommended to use the Domain interface for conditions, which has not changed)
    • ParamSet has new fields $is_logscale, $has_trafo_param (per-param), and $has_trafo_param (scalar for the whole set).
  • Added a vignette which was previously a chapter in the mlr3book

  • Reset .has_extra_trafo to FALSE when trafo is set to NULL.
  • rd_info.ParamSet collapses vector with "\n" due changes in roxygen 7.2.0
  • Add method set_values() to conveniently add parameter values.

  • Parameters now have a new (optional) field description.
  • Improved printing of parameters in documentation (#355).

  • Fixed some links.

  • Sampler1D also accept ParamSets with one Param now (#335).
  • Fixed sampling zero rows in Sampler1DRfun (#338).
  • to_tune(), p_dbl(), and p_int() accept logscale argument for tuning on
    a logarithmic scale.
  • to_tune can be called with only lower or only upper now and will infer
    the other bound if possible.

  • ParamSet$get_values() checks whether all required parameter values are set.
    Required parameter are not checked anymore when new values are added to the
    parameter set.
  • ParamSet$check_dt() accepts data.frames.
  • Rename is_numeric and is_categorical to all_numeric and
    all_categorical.
  • Rename requires to depends.

  • ps() shortcuts for ParamSet construction, with new Domain construct and
    constructors p_dbl, p_int, p_lgl, p_fct, and p_uty.
  • ParamSet$search_space() method that constructs tunable ParamSet from
    TuneToken objects, which are constructed with to_tune().

    saving objects via saveRDS(), serialize() etc.
  • Improved performance for ParamSetCollection.
