trainSurrogates: Training surrogates for objective and constraint functions

In SACOBRA: Self-Adjusting COBRA

Description

This function is called during the second phase of SACOBRA cobraPhaseII to train the surrogate models for objective and constarint functions of the optimization problem passed to the SACOBRA framework. This function takes all the so-far evalauted points stored in cobra$A and builds

Usage

trainSurrogates(cobra)

Arguments

cobra

an object of class COBRA, this is a (long) list containing all settings from cobraPhaseII

Value

cobra, an object of class COBRA, with the following elements modified:

constraintSurrogates	surrogate models for all constraints
fitnessSurrogate	surrogate model for objective function
fitnessSurrogate1	surrogate model for objective function, w/o plog
fitnessSurrogate2	surrogate model for objective function, with plog
