Abstract

A parameter fitting unit (3) is configured to include: a data acquisition unit (11) to acquire data containing a value of each of parameters and a rating value with respect to the value of each of parameters from a rating value calculation unit (2), which acquires an operating result of a fitting unit (1) that performs an operation using one or a plurality of parameters, and which calculates a rating value for the operating result; and an elite solution extraction unit (12) to extract zero or more pieces of data as an elite solution from a plurality of pieces of data acquired by the data acquisition unit (11), based on a rating value contained in each of the pieces of data.Furthermore, the parameter adjustment device (3) includes a parameter value determination unit (14) to determine a value of a parameter to be used for the next operation by the device (1) to be adjusted, based on the elite solution extracted by the elite solution extraction unit (12) from a plurality of parameter values ​​present in a parameter value search space, and to output the determined parameter value to the device (1) to be adjusted.
