(Recommended) Replace points in the surrogate training set, instead of appending
Alias: none
Argument(s): none
Default: Points appended, not replaced
The user has the option of appending the optimal points from the surrogate model to the current set of truth points or using the optimal points from the surrogate model to replace the optimal set of points from the previous iteration. Although appending to the set is the default behavior, at this time we strongly recommend using the option replace_points
because it appears to be more accurate and robust.
