As the extreme point calculation is happening as a weighted and aggregated optimization (max(__F * weights)), I think it would be better to normalize __F beforehand. Otherwise, the resulting extreme points could have a bias towards objective functions (F) with higher magnitude (in case the objective values of different objective functions are highly unbalanced).
