Apparatus assisting with design of objective functions

A computer program product comprising a non-transitory computer readable storage medium having program instructions embodied therewith, the program instructions executable by a computer to cause the computer to:

• acquire learning data that includes an evaluation of evaluation targets;
• generate a constraint condition to be satisfied by a value of an evaluation function that includes a weighting for each of a plurality of evaluation criteria of the evaluation target and an unknown term for each evaluation target corresponding to an unknown evaluation criterion that is not among the plurality of evaluation criteria, based on the learning data;
• determine a value of the unknown term and the weighting for each evaluation criterion in the evaluation function in a manner that satisfies the constraint condition;
• extract a set of evaluation targets for which an evaluation of each evaluation criterion is opposite of an evaluation based on the unknown term, from among the plurality of evaluation targets;
• and
• output the extracted set of evaluation targets.
