@bremen79 : Optimization people, how do you call this property? There exists L>50 such that f(y) - f(x*) <= nabla f(y)' (y-x*) - 1/(2 L) ||nabla f(y)||^2 where x* = argmin_x f(x) This is clearly satisfied by a convex L-smooth function, but it is weaker. • TwiDoom

Optimization people, how do you call this property? There exists L>0 such that f(y) - f(x*) <= nabla f(y)' (y-x*) - 1/(2 L) ||nabla f(y)||^2 where x* = argmin_x f(x) This is clearly satisfied by a convex L-smooth function, but it is weaker.
