1. An apparatus comprising:
a hardware processor operatively coupled to one or more computer readable storage mediums collectively including instructions that, when executed by the processor, cause the processor to perform the method of:
acquiring an initial candidate for optimizing a third objective function based on a first objective function and a second objective function;
obtaining a first solution optimizing the second objective function under a constraint corresponding to a value of the first objective function, and a second solution optimizing the first objective function using the first solution, the second solution being assigned as the constraint in a next iteration of obtaining a plurality of candidates;
increasing processing speed and efficiency for the obtaining the plurality of candidates by monotonically decreasing the constraint during calculation of an optimization solution for the third objective function corresponding to the constraint; and
selecting, as the optimization solution for the third objective function, one of the plurality of candidates associated with an optimized relationship between the first solution and the second solution.
