Times ” More Difficult to Approximate Than

How many points do we need to approximate a given metric space S (e.g., a ball in the Euclidean space) with a given accuracy ε > 0? To be more precise, how many points do we need to reproduce the metric ρ(X, Y ) on S with an accuracy ε? This problem is known to be equivalent to the following geombinatoric problem: find the smallest number of balls of given radius ε that cover a given set S. A s...
