الوصف: | We present bounds between different widths of convex subsets of Banach spaces, including Gelfand and Bernstein widths. Using this, and some relations between widths and minimal errors, we obtain bounds on the maximal gain of adaptive and randomized algorithms over non-adaptive, deterministic ones for approximating linear operators on convex sets. Our results also apply to the approximation of embeddings into the space of bounded functions based on function evaluations, i.e., to sampling recovery in the uniform norm. We conclude with a list of open problems. |
