Onemax helps optimizing XdivK:
Maxim Buzdalov, Буздалова Арина Сергеевна · 2014
There exist optimization problems with the target objective, which is to be optimized, and several extra objectives, which can be helpful in the optimization process. The previously proposed EA+RL method is designed to adaptively select objectives during the run of an optimization algorithm in order to reduce the number of evaluations needed to reach an optimum of the target objective.
