Abstract

This paper considers {\sl binary space partition}s (BSP for short) for $n$ disjoint line segments in the plane. The BSP for a disjoint set of objects is a scheme dividing the space recursively by hyperplanes until the resulting fragments of objects are separated. The size of a BSP is the number of resulting fragments of the objects. We show that the minimal size of a BSP for $n$ disjoint line segments in the plane is $\Omega (n \log n / \log \log n)$ in the worst case. The best known upper bound due to Paterson and Yao is $O(n \log n)$.
