Web5 Jul 2016 · Comparing to smoothness, convexity is a more important for cost functions. A convex function is easier to solve comparing to non-convex function regardless the smoothness. In this example, function 1 is non-convex and smooth, and function 2 is convex and none-smooth. Performing optimization on f2 is much easier than f1.
