WebbThe Bowyer–Watson algorithm provides another approach for incremental construction. It gives an alternative to edge flipping for computing the Delaunay triangles containing a newly inserted vertex. Unfortunately the flipping-based algorithms are generally hard to parallelize, since adding some certain point (e.g. the center point of a wagon wheel) can … WebbNotes on Randomized Incremental Algorithms • Randomized Incremental Algorithms first used for computing the intersection of half-planes.

"WebbA randomized algorithm is an algorithm that employs a degree of randomness as part of its logic. The algorithm typically uses uniformly random bits as an auxiliary input to guide its behavior, in the hope of achieving good performance in the "average case" over all possible choices of random determined by the random bits; thus either the running time, … " - Randomized incremental algorithm

Webb4.2 Randomized Incremental Algorithms The two algorithms above relied on the use of random sampling to run the simplex algorithm on a problem with a smaller number of constraints. We will now study a randomized incremental algorithm which takes a different approach. The idea is to randomly choose a constraint and throw it out if it is redundant. WebbWe develop two randomized algorithms for the p-KEP L = 3 and the p-KEP. By stochastically partitioning the vertex set V into two subsets V 2 and V 3 which respectively contains 2-cycle or 3-cycle exchanges of the solution for a given instance, we propose a randomized algorithm of running time O * (4.6 3 k 3 · 2 2 k 2) for the p-KEP L = 3.
