paradox 1.0.1

• Performance improvements.

paradox 1.0.0

• 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

paradox 0.11.1

• Minor bug fixes.

paradox 0.11.0

• feat: The function generate_design_sobol() generates a space-filling Sobol sequence design.
• refactor: $set_values returns the parameter set invisible.

paradox 0.10.0

• 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.

paradox 0.8.0

• Parameters now have a new (optional) field description.
• Improved printing of parameters in documentation (#355).
• A warning is now signaled if the package ParamHelpers is also loaded.
• Fixed some links.

paradox 0.7.1

• 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.

paradox 0.7.0

• 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.

paradox 0.6.0

• 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().

paradox 0.5.0

• Compact in-memory representation of R6 objects to save space when
  saving objects via saveRDS(), serialize() etc.
• Improved performance for ParamSetCollection.
