Calculate Nadir point

shdotcom

Hi, Dear Felipe Campelo, Would you please explain how did you get these formulations to calculate Nadir point in In DTLZ5, 6 and Nadir, faux and zstar in DTLZ7? ``` case {'dtlz5', 'dtlz6'} zstar = zeros(M,1); znad = (1/sqrt(2)) .^ ([M-2, M-2:-1:0]'); case 'dtlz7' xaux = 0.85940; faux = 2*(M - (M-1)*xaux/2*(1 + sin(3*pi*xaux))); zstar = [zeros(M-1,1); faux]; znad = [xaux(ones(M-1,1)); 2*M]; ``` And how did you get this value xaux = 0.85940; in DTLZ7? Thank you

Hi, shdotcom, I believe this question was properly answered during our private conversations. For other users with the same inquiry, I moved the DTLZ code to a separate repository: [https://github.com/fillipe-gsm/dtlz-test-functions](url) and added a pdf file inside the `docs` folder explaining the derivation of these equations. With that said, I suppose this issue can be closed.
