| Outline of Final Research Achievements |
This study has developed a technology to simultaneously optimize multiple problems in different fields but related to each other. The proposed method treats problems as independent subproblems and optimizes using existing methods and/or heuristics of the problems in the form of coevolution, rather than formulating them as one big problem. Unlike the conventional method, the proposed method avoids local optima. This study has also applied the above method to design of digital watermark for authentication of two-dimensional code. Simultaneously designing watermarking scheme and coded aperture pattern for watermark extraction, the depth of field of watermark extraction was successfully extended.
