objective GPR prediction #12

Hi, May I know the reason for using the negative sign for the GPR prediction in the __ObjectiveGP method?

ppgaluzio commented 4 years ago

The method was originally designed to find only the max of the objectives, and the NSGA2 implementation that I used was designed to find their min. The minus sign is there for that reason. The max_or_min keyword was added to the code only in a latest review.
