We describe a fully dynamic linear-space data structure for point location in connected planar subdivisions, or more generally vertical ray shooting among nonintersecting line segments, that supports queries in $O(\log n(\log\log n)^2)$ time and updates ...
This paper describes new methods for maintaining a point-location data structure for a dynamically changing monotone subdivision $\cal S$. The main approach is based on the maintenance of two interlaced spanning trees, one for $\cal S$ and one for the ...
Let $S$ be a set of $n$ points in $\IR^{D}$. It is shown that a range tree can be used to find an $L_{\infty}$-nearest neighbor in $S$ of any query point, in $O((\log n)^{D-1} \log\log n)$ time. This data structure has size $O(n (\log n)^{D-1})$ ...
