randomized algorithmdivide-and-conquerpathmatchingset packingWe propose a randomized divide-and-conquer technique that leads to improved randomized and deterministic algorithms for NP-hard path, matching, and packing problems. For the parameterized max-path problem, our randomized algorithm runs in time ...
Higher-order Voronoi diagram Abstract Voronoi diagram k nearest neighbors Geometric randomized algorithm Divide and conquer 1. Introduction Given a set S of n geometric sites in the plane, their order-k Voronoi diagram, Vk(S), is a planar subdivision such that every point within an order-k Vor...
A simple randomized divide-and-conquer algorithm, with Omn+nlogn) expected running time, was recently proposed by Agarwal et al. [20]. Using random sampling, they improved the expected running time to Om2/3n2/3log2/3n/m+m+nlogn. If we are interested in computing the incidences between...
Quicksort is a divide and conquer algorithm. Quicksort first divides a large array into two smaller sub-arrays: the low elements and the high elements. Quicksort can then recursively sort the sub-arrays. Randomized quick sort is also similar to quick sort, but here the pivot element is rand...
Quicksort is an alternative algorithm, which is simpler to implement in practice. Quicksort will also use a divide and conquer strategy but will use randomization to improve the performance of the algortithm in expectation. Java, Unix, and C stdlib all have implementations of Quicksort as one...

Figure 1. Our algorithm can be seen as a divide-and-conquer search process. We recursively cluster skeletal joints and divide the part under exploration into two finer sub-regions until reaches a leaf node, which represents the position of a skeletal joint. This figure shows two examples of ...
