- refactor: The
$print()

raised an error. - fix: The
$clear()
method ofArchive
missed to reset the$start_time
field. - feat:
Optimizer
andTerminator
objects have the optional field$label
now. - feat:

have been extended with additional columns. - feat: Add a

method ofTerminatorRunTime
andTerminatorClockTime
was not in a consistent unit. The return is in seconds from now on. - fix: The number of evaluations was recorded as 0 in the log messages when the search space was empty.
- feat: Add a
as.data.table.DictionaryOptimizer()
function. - feat: New
$help()
method which opens the manual page of anOptimizer
.
- feat: Add
$nds_selection()

From now on, only unnamed returns of
ObjectiveRFun
are named. - fix:
OptimInstance
,Archive
andObjective
objects were not cloned properly. - refactor: The fields
$param_classes
,$properties
and$packages
ofOptimizer
objects are read-only now. - feat: The
branin()
function is exported now.

- feat: The budget of
TerminatorEvals
can now be changed depending on the dimension of the search space with the parameterk

bb_optimize()
function. - feat: Add
OptimizerIrace
which callsirace::irace
from theirace
package.
- refactor: Internal changes.
- feat: Add
$clear()

to reset the instance. - refactor: Prettier
$print()
methods. - feat: Assertions on overlapping and reserved names in domain and codomain.
- feat: The check of points and results can now be disables with the
check_values
flag inOptimInstance
,OptimInstanceSingleCrit
,OptimInstanceMultiCrit
,ObjectiveRFun
andObjectiveRFunDt
. - refactor: The
data.table
within theArchive
can now be accessed with$data
. - refactor: The
m
parameter ofArchive$best()
is renamed tobatch
. - feat: New

class which only stores best scoring evaluation instead of all evaluations - refactor: The runtime is reduced when
ObjectiveRFunDt
is used with a domain without trafo. - fix: Add support for
ParamUty
inOptimizerDesignPoints

OptimizerCmaes
andOptimizerNloptr
can now be randomly created or from center of the search space. - feat: The
