  • Optimization method and optimization apparatus
    Patent number: 7587375
    Abstract: The solution of a constrained optimization problem is easily solved by linearly approximating a point of interest to a first hypersurface given as a constraint and finding the extreme value of the objective function by moving a point r along a curved line having second-order osculation with the geodetic line of a hypersurface S(r)=c and passing through the point r.
    Type: Grant
    Filed: March 9, 2005
    Date of Patent: September 8, 2009
    Assignee: Canon Kabushiki Kaisha
    Inventors: Akira Asai, Shigeki Matsutani, Katsuhiko Shinjo, Masanori Kuroda, Daichi Tsutsumi
