Outline of Final Research Achievements |
This research aims to develop efficient methods for solving nonconvex feasibility problems. To deal with the non-convex constraint sets, we have investigated modification of a variety of optimization methods, such as fixed-point approximation methods, the proximal gradient method, the projection methods, the Douglas-Rachford method. In particular, we have presented some relevant convergence rate results for fixed-point approximation method and the proximal point algorithm. Moreover, we have investigated theoretical and numerical properties of the proposed methods.
