Use information from the existing surrogate model to predict what the surrogate upgrade will be with new points.

Specification

Alias: none

Argument(s): none

Description

The strategy first selects the highest scoring candidate, and then refits the surrogate using a ''lie'' value at the point selected. The 'lie' value is based on the surrogate predictions and not the simulation. This process repeats until n points have been selected whereupon the lie values are removed from the surrogate and the selected points are evaluated on the true model and the surrogate is refit with these values.
