Patent Searching and Data


Title:
OPTIMIZATION DEVICE, OPTIMIZATION METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2019/208639
Kind Code:
A1
Abstract:
The present invention makes it possible to optimize a parameter with less evaluations. For each of a plurality of search point candidates, which are parameters serving as search point candidates and generated by a search point candidate generation unit 120 on the basis of a parameter used in a plurality of calculations, a search point determination unit 130 uses a plurality of data points to determine whether to set a search point candidate as a search point, said plurality of data points comprising a set of parameters used in a calculation by an evaluation unit 300 and evaluation values calculated by using, as search points, the parameters used in the calculation by the evaluation unit 300.
