debugVisualizeRBF: Optional visualization of surrogate models for 2-dimensional...

In SACOBRA: Self-Adjusting COBRA

Description

Optional visualization of surrogate models for 2-dimensional problems, d=2.

Usage

debugVisualizeRBF(cobra, fitnessSurrogate, A, Fres)

Arguments

fitnessSurrogate	The surrogate model for the objective function
A	The whole population of solutions which is a matrix of n times d, where n is the number of solutions and d is the dimension of problem, here d=2
Fres	The objective value on the evaluated solutions A
cobra	parameter list, we need here DEBUG_RBF$overlayTrueZ =T: overlay the true objective function DEBUG_RBF$DO_SNAPSHOT =T: do rgl.snapshot every DEBUG_RBF$every iteration and store it in sprintf("images.d/%s-%03d.png",cobra$fname,npts) DEBUG_RBF$every see above

Value

cobra, an object of class COBRA, with modified items:

TrueZ	True objective values of the evaluated points used for viusalization
TrueFeas	A vector of values 0: for infeasible evaluated points or 1: for feasible points.
globalDevice

This function is called only if cobra$DEBUG_RBF$active==T. An assertion fires if cobra$dimension!=2 or if cobra$rescale==F.
