Outline of Final Research Achievements

This research integrated the theory and application of optimization in various fields of engineering and social sciences by Discrete Convex Paradigm. We analyzed the theory and applications of discrete convex analysis, to clarify the mutual relationship of the individual mathematical techniques and problems in applications, from three aspects of the continuous-discrete axis, the convex-nonconvex axis, and the fields-transversal axis. Also we conducted research from three aspects of mathematical deepening, applications development, and software development, and achieved the new developments in Discrete Convex Paradigm. In particular, mathematical deepening includes the results of detailed analysis in L-convex function minimization algorithm and presentation of a framework of discrete DC programming.
