This class takes multiple Terminators and terminates as soon as one or all of the included terminators are positive.
This Terminator can be instantiated via the
dictionary mlr_terminators or with the associated
sugar function trm():
mlr_terminators$get("combo")
trm("combo")
anylogical(1)
Terminate iff any included terminator is positive? (not all).
Default is TRUE.
bbotk::Terminator -> TerminatorCombo
terminators(list())
List of objects of class Terminator.
Inherited methods
new()Creates a new instance of this R6 class.
TerminatorCombo$new(terminators = list(TerminatorNone$new()))terminators(list())
List of objects of class Terminator.
is_terminated()Is TRUE iff the termination criterion is positive, and FALSE
otherwise.
TerminatorCombo$is_terminated(archive)archive(Archive).
logical(1).
...(ignored).
remaining_time()Returns the remaining runtime in seconds. If any = TRUE, the remaining
runtime is determined by the time-based terminator with the shortest time
remaining. If non-time-based terminators are used and any = FALSE,
the the remaining runtime is always Inf.
TerminatorCombo$remaining_time(archive)archive(Archive).
integer(1).
status_long()Returns max_steps and current_steps for each terminator.
TerminatorCombo$status_long(archive)archive(Archive).
clone()The objects of this class are cloneable with this method.
TerminatorCombo$clone(deep = FALSE)deepWhether to make a deep clone.
