DC programming and DCA: thirty years of developments

WebApr 10, 2024 · Mathematical programming problems dealing with functions, each of which can be represented as a difference of two convex functions, are called DC programming problems. WebGiven a linear space X, a DC program is an optimization problem in which the objective function f : X → R can be represented as f = g−h, where g, h : X → R are convex functions. This extension of convex programming enables us to take advantage of the available tools from convex analysis and optimization.
