repairChootinan: Repair an infeasible solution with the method of Chootinan.

In SACOBRA: Self-Adjusting COBRA

Description

Implements the method of [Choo2006] Chootinan & Chen "Constraint handling in genetic algorithms using a gradient-based repair method", Computers & Operations Research 33 (2006), p. 2263.

Usage

repairChootinan(x, gReal, rbf.model, cobra, checkIt = FALSE)

Arguments

x	an infeasible solution vector \vec{x} of dimension d
gReal	a vector (g_1(\vec{x}),…,g_m(\vec{x}), h_1(\vec{x}),…,h_r(\vec{x})) holding the real constraint values at \vec{x}
rbf.model	the constraint surrogate models
cobra	parameter list, we need here lower lower bounds of search region upper upper bounds of search region ri a list with all parameters for repairChootinan trueFuncForSurrogate if TRUE (only for diagnostics), use the true constraint functions instead of the constraint surrogate models rbf.model fn true functions, only needed in case of trueFuncForSurrogate==TRUE
checkIt	[FALSE] if TRUE, perform a check whether the returned solution is really feasible. Needs access to the true constraint function conFunc

Value

z, a vector of dimension d with a repaired (hopefully feasible) solution
