(LaTeX) Abstract:
Given a set of points $P\subseteq \RR^2$, a \emph{conflict-free coloring} of $P$ is an assignment of colors to points of $P$,
such that each non-empty axis-parallel rectangle $T$ in the plane contains a point whose color is distinct from all other points
in $P\cap T$.
This notion has been the subject of recent interest, and is motivated by frequency assignment in wireless
cellular networks: one naturally would like to minimize the number of frequencies (colors) assigned to bases stations (points),
such that within any range (for instance, rectangle), there is no interference.
We show that any set of $n$ points in $\RR^2$ can be conflict-free colored with $\tO(n^{.382+\epsilon})$ colors
in expected polynomial time, for any arbitrarily small $\eps > 0$.
This improves upon the previously known bound of $O(\sqrt{n\log\log n/\log n}$).
