WebConvex optimization problems arise frequently in many different fields. It is usually described as a minimization problem because the maximization of the real-valued function () is equivalent to the minimization of the function ():= ().. Basics of convex analysis. To make this procedure more robust, you can rerun your optimization algorithm with different initializations and pick the lowest/highest return value. The aim is to develop the core analytical and algorithmic issues of continuous optimization, duality, and saddle point theory using a handful of unifying principles that can be easily visualized and readily understood.
