### Exam 2020 Q18

Hi,

Is it False because we don't need "a bounded and convex constraint set"? In the lecture, properties of the set are indeed not mentioned (only $$X \subseteq \mathbb{R}^n$$) but why we work in a so wide setting where X can be the whole space and then Frank-Wolfe is unable to do even one step? Should we have at least some restrictions on the set?

The problem miss the statement that s=LMO(gradient f).

Isn't it because it should be O(1/T) and not O(1/t)?
