When I call the platemo function like this:
platemo('algorithm',@NSGAII, 'objFcn', objFcn, 'encoding', [1 2 2 2 1 1], ... 'lower', u_lb, 'upper', u_ub,... 'N', 60, 'maxFE', 10000, 'once',1,'save',20, 'run',0408);
The saved results look like this:

It appears that nothing useful are saved at all. Is this a bug?
