Las Vegas and Monte Carlo Algorithms

NettetLas Vegas Alogrithm. Recall the algorithm: it rst divides a large array into two smaller sub-arrays: the low elements and the high elements. Quicksort can then recursively sort the sub-arrays. Example: to sort a list of numbers a[] = 4, 2, 8, 6, 3, 1, 7, 5. We rst pick a random pivot number (say 3).

A simple randomized algorithm is developed which computes the smallest enclosing disk of a finite set of points in the plane in expected linear time. The algorithm is based on Seidel's recent Linear Programming algorithm, and it can be generalized to computing smallest enclosing balls or ellipsoids of point sets in higher …
