(list())
List of objects of class Terminator.

Methods

Inherited methods


Method new()

Creates a new instance of this R6 class.

Usage

TerminatorCombo$new(terminators = list(TerminatorNone$new()))

Arguments

terminators

(list())
List of objects of class Terminator.


Method is_terminated()

Is TRUE iff the termination criterion is positive, and FALSE otherwise.

Usage

TerminatorCombo$is_terminated(archive)

Arguments

archive

(Archive).

Returns

logical(1).


Method print()

Printer.

Usage

TerminatorCombo$print(...)

Arguments

...

(ignored).


Method 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.

Usage

TerminatorCombo$remaining_time(archive)

Arguments

archive

(Archive).

Returns

integer(1).


Method status_long()

Returns max_steps and current_steps for each terminator.

Usage

TerminatorCombo$status_long(archive)

Arguments

archive

(Archive).


Method clone()

The objects of this class are cloneable with this method.

Usage

TerminatorCombo$clone(deep = FALSE)

Arguments

deep

Whether to make a deep clone.

Examples

trm("combo",
  list(trm("clock_time", stop_time = Sys.time() + 60),
    trm("evals", n_evals = 10)), any = FALSE
)
#> <TerminatorCombo>
#> * Parameters: any=FALSE
#> * Terminators: <TerminatorClockTime>,<TerminatorEvals>
