Bottleneck Non-crossing Matching in the Plane,dy the problem of computing ... We present an .(..log..)-time algorithm that computes a non-crossing matching . of ., such that ., where .(.) is the length of a longest edge in .. An interesting implication of our construction is that .. We also show that when the points of . are in convex position,

Lower Bounds for Sorted Geometric Queries in the I/O Model,h attention so far. Two of the most prominent problems in this class are angular sorting queries and sorted .-nearest neighbour queries. The former asks us to preprocess an input point set . in the plane so that, given a query point ., the clockwise ordering of the points in . around . can be comput

I/O-efficient Hierarchical Diameter Approximation,ently approximated (and frequently even exactly determined) using heuristics that apply a limited number of BFS traversals. If the input graphs have to be kept and processed on external storage, even a single BFS run may cause an unacceptable amount of time-consuming I/O-operations..Meyer [17] propo

The idea of taking linear combinations of inequalities used in Aggarwal .[1] is crucial in achieving this result. The example proposed by Zhang . also shows t

A Bicriteria Approximation for the Reordering Buffer Problem,ust move to the corresponding point in the metric. The requests can be processed slightly out of order; in particular, the server has a buffer of capacity . which can store up to . requests as it reads in the sequence. The goal is to reorder the requests in such a manner that the buffer constraint i
