We consider the problem of 2-coloring geometric hypergraphs. Specifically, we show that there is a constant such that any finite set of points in the plane can be 2-colored such that every axis-parallel square that contains at least points from contains points of both colors. Our proof is constructive, that is, it provides a polynomial-time algorithm for obtaining such a 2-coloring. By affine transformations this result immediately applies also when considering 2-coloring points with respect to homothets of a fixed parallelogram. |
