max_EHVI: Maximization of the Expected Hypervolume Improvement criterion
Description
Given an object of class mkm
and a set of tuning parameters,
max_EHVI performs the maximization of the Expected Hypervolume Improvement
criterion and delivers the next point to be visited in an HEGOlike
procedure.
Usage
1 2 
Arguments
model 
An object of class 
lower 
Vector of lower bounds for the variables to be optimized over
(default: 0 with length 
upper 
Vector of upper bounds for the variables to be optimized over
(default: 1 with length 
control 
An optional list of control parameters, some of them passed to
the

optimcontrol 
Optional list of control parameters passed to the

Value
A list with components:
par
The best set of parameters found.
value
The value of expected hypervolume improvement at par.
