Problems in Ramsey theory typically ask a question of the form: "how many elements of some structure must there be to guarantee that a particular property will hold?“. Here we consider geometric Ramsey-type results about finite point sets in the plane.. Given a set of points (x. 1. ,y. 1. ),(x. 2. ,y. 2. ),…,(x. n. ,y. n. ), the . convex hull. is the smallest convex polygon containing all the points.. Convex Hulls. Given a set of points (x. 1. ,y.

Strengths of Hierarchical Clustering. What is clustering?. Grouping set of documents into subsets or clusters.. The Goal of clustering algorithm is:. To create clusters that are coherent internally, but clearly different from each other. Nicholas . Ruozzi. University of Texas at Dallas. Where We’re Going. Multivariable calculus tells us where to look for global optima, but our goal is to design algorithms that can actually find one!.
