Fast and Robust Smallest Enclosing Balls

Part of the Lecture Notes in Computer Science book series (LNCS,volume 1643)

Abstract

I describe a C++ program for computing the smallest enclosing ball of a point set in d-dimensional space, using floating-point arithmetic only. The program is very fast for d ≤ 20, robust and simple (about 300 lines of code, excluding prototype definitions). Its new features are a pivoting approach resembling the simplex method for linear programming, and a robust update scheme for intermediate solutions. The program with complete documentation following the literate programming paradigm [3] is available on the Web.1

Keywords

  • Singular Value Decomposition
  • Support Point
  • Recursive Call
  • Input Point
  • Current Ball

These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
