Hi again, I believe the Dakota code somehow hide some of points after running the simulation. I have used the LHS to simulate 2000 samples. Then I used those 2000 points for Kriging surrogate model. The Pareto front looks good but with fewer points than LHS. I want to know this is normal or I missed something? Regards

Hi, Yes, out of 2000 samples from LHS, only fewer points are shown in Kriking. What I did is: 2000 samples with LHS then, running the Dakota (Kriking) and I ticked the LHS before running. after that, there are not 2000 points but less. Regards

Dear Mr. Heinrich von Zadow, Hello again and thank you for your reply I need some help regarding a Pareto fronts obtained from the Dakota code. I have used LHS to generate 2000 samples, and then I used Dakota with Kriging approximation based on LHS samples to generate a surrogate model. the graph shows less points and Pareto fronts, why after running the Dakota we cannot see those 2000 points anymore. It seems Dakota somehow select some points based on some algorithm and remove other points. How can I explain this in my report? Please see the attached pictures. Best Regards
