Cextrap {caRamel} | R Documentation |
gives n new candidates by extrapolation along orthogonal directions to the Pareto front in the space of the objectives
Cextrap(param, crit, directions, longu, n)
param |
: matrix [ NPoints , NPar ] of already evaluated parameters |
crit |
: matrix [ Npoints , NObj ] of associated criteria |
directions |
: matrix [ NDir, 2 ] the starting and ending points of the candidate vectors |
longu |
: matrix [ NDir , 1 ] giving the length of each segment thus defined in the OBJ space (measure of the probability of exploring this direction) |
n |
: number of new vectors to generate |
xnew : matrix [ n , NPar ] of new vectors
pcrit : matrix [ n , NObj ] estimated positions of new sets in the goal space
