Table of Contents

Problem Statement

A Voronoi diagram is a diagram consisting of a number of sites. Each Voronoi site s also has a Voronoi cell consisting of all points closest to s.

Demonstrate how to generate and display a Voroni diagram.

See algo K-means++ clustering.

Let's start with the solution:

Source code in the j programming language

NB. (number of points) voronoi (shape)
NB. Generates an array of indices of the nearest point
voronoi =: 4 :0
  p =. (x,2) ?@$ y
  (i.<./)@:(+/@:*:@:-"1&p)"1 ,"0/&i./ y
)
