<P>PROBLEM TO BE SOLVED: To obtain a solution of an optimization problem for two or more objective functions at high speed with a mathematical expression. <P>SOLUTION: A method includes: a step for causing a CAD (Cylindrical Algebraic Decomposition) processing unit to execute projection processing on a first polynomial expression appearing in a qualifier rejection problem equivalent to an optimization problem including a plurality of objective functions to generate second expressions which are projection factors of the first expression, and acquiring data of the second expressions from the CAD processing unit; a step for generating a plurality of values of variables for the plurality of objective functions, calculating a plurality of value sets of the plurality of objective functions by substituting the generated values of variables into the plurality of objective functions, and extracting provisional optimal points which are non-inferior solution in spaces extending between the values of the plurality of objective functions from the plurality of value sets; a step for calculating, for each second expression, evaluation values for distances between the second expression and respective provisional optimal points; and a step for determining a second expression with the smallest evaluation value. <P>COPYRIGHT: (C)2012,JPO&INPIT |
