| 英文摘要 | In this paper we present a simple factor-(3 + epsilon), 0 < epsilon < 1, approximation algorithm, which runs in O(n log n + n(1/epsilon)(O(1/epsilon2)) log(D-3/epsilonD(2))) time, for the problem of labeling a set P of n distinct points with uniform circles. (D-2 is the closest pair Of P and D-3 is the minimum diameter of all subsets of P with size three.) This problem is known to be NP-hard. Our bound improves the previous factor of 3.6 + epsilon.
