Abstract
This paper focuses on approximating the metric 1-median problem with sublinear number of queries and time complexity. We first show a simper proof of the currently best 4-approximation algorithm, and then propose a recursive algorithm. For any integer h⩾2, the algorithm finds a 2h-approximation solution with O(n1+1/h) queries and time complexity.
