Abstract in LaTeX format:
An algorithm is presented that, given a set of $n$ points in
the plane and an integer $k$, $2 \leq k \leq n$,
finds $k$ points with a smallest enclosing
axes-parallel square. The algorithm has a running time of
$O(n \log n + kn \log^{2} k)$ and uses $O(n)$ space.
The previously best known algorithm for this problem takes
$O(k^{2} n \log n)$ time and uses $O(kn)$ space.
