Web8 Feb 2024 · But it is a sufficient, not necessary condition (as evidenced by f ( x) = sin. . ( x) is L -smooth.) Proof of statement 3: This is pretty simple, and we can just go after [Q2]: if f … Webnot necessarily smooth, the key difficulty is to construct a smooth Lyapunov function. An important special case is when kk c = kk 1, which is applicable to many RL algorithms. We provide a solution to this where we construct a smoothed convex envelope M(x) called the Generalized Moreau Envelope that is smooth w.r.t. some norm kk
