Approximating extent measures of points.
We present a general technique for approximating various descriptors of the extent of a set P of n points in Rd when the dimension d is an arbitrary fixed constant. For a given extent measure μ and a parameter ϵ > 0, it computes in time O(n + 1/ϵO(1)) a subset Q ⊆ P of size 1/...
