Center node: "approximate range queries for clustering"
  Abstract: We study the approximate range searching for three variants of the clustering problem with a set $P$ of $n$ points in $d$-dimensional Euclidean space and axis-parallel rectangular range queries: the $k$-median, $k$-means, and $k$-center range-clustering query problems. We present data structures and query algorithms that compute $(1+\varepsilon)$-approximations to the optimal clusterings of $P\cap Q$ efficiently for a query consisting of an orthogonal range $Q$, an integer $k$, and a value $\varepsilon>0$.

Connected through hyperedge HE-1 (induced by source paper "searching for the closest pair in a query translate"):

    - "colored range closest pair problem under general distance functions"
    - "new bounds for range closest pair problems"
    - "range clustering queries"
